ACTION: Notice of proposed rulemaking (NPRM). hsrobinson on PROD1PC76 with PROPOSALS AGENCY: SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008–06– 28 R1, which applies to certain Avidyne Corporation (Avidyne) Primary Flight Displays (PFDs) (part numbers (P/Ns) 700–00006–000, –001, –002, –003, and –100) that are installed on airplanes. AD 2008–06–28 R1 currently requires you to do a check of the maintenance records and inspection of the PFD (if necessary) to determine if an affected serial number PFD is installed and incorporate (if necessary) operational limitations. Since we issued AD 2008– 06–28 R1, Avidyne developed a factory service procedure that will correct the VerDate Aug<31>2005 16:24 Nov 13, 2008 Jkt 217001 problems on these Avidyne PFDs and also factory serviced certain serial number PFDs. Consequently, this proposed AD would retain the actions from AD 2008–06–28 R1 until the affected PFD is factory serviced; add the actions of a label or marking check, an air data system performance verification test, and (if necessary) replacement of the PFD and factory servicing of the failed PFD; and reduce the serial number applicability from that of AD 2008–06–28 R1. We are proposing this AD to prevent certain conditions from existing when PFDs display incorrect attitude, altitude, and airspeed information. This could result in airspeed/altitude mismanagement or spatial disorientation of the pilot with consequent loss of airplane control, inadequate traffic separation, or controlled flight into terrain. DATES: We must receive comments on this proposed AD by January 13, 2009.

We will also post a report summarizing each substantive verbal contact we receive concerning this proposed AD. Discussion Several field reports of PFDs displaying incorrect altitude and airspeed information caused us to issue AD 2008–06–28, Amendment 39–15440 (73 FR 15862, March 26, 2008). AD 2008–06–28 required the following on Avidyne PFDs (P/Ns 700–00006–000, –001, –002, –003, and –100) that are installed on airplanes: • Checking of the maintenance records and inspection of the PFD (if necessary) to determine if an affected serial number PFD is installed; and • If an affected serial number PFD is installed, incorporating information that limits operation when certain conditions for the PFD or backup instruments exist. An incorrect serial number (SN) listed in AD 2008–06–28 caused us to issue AD 2008–06–28 R1, Amendment 39– 15468 (73 FR 19963, April 14, 2008). AD 2008–06–28 R1 corrects the incorrect SN and retains the actions of AD–2008– 06–28. Since we issued AD 2008–06–28 R1, Avidyne has prepared a factory service procedure that will correct the possible incorrect altitude and airspeed information displayed on these Avidyne PFDs and received approval for a corresponding alternative method of compliance (AMOC) to modify certain serial number PFDs at the factory, eliminating the unsafe condition in these units. This proposed AD retains the actions from AD 2008–06–28 R1 until the factory servicing is done. This proposed AD would require you to inspect for a label marked ‘‘Deviation 08–19A’’ on the exterior of the PFD near the TSO label or a ‘‘MOD 52’’ marking; if the label or mark is not present, do the PFD air data system performance verification test; if the PFD passes the test, remove the operational limitations requirement; or if the PFD does not pass the test, remove the PFD, have the PFD factory serviced, install a PFD that has passed the air data system verification test or has been factory serviced (PFD bears a label marked ‘‘Deviation 08–19A’’ on the exterior of the PFD near the TSO label; or a ‘‘MOD 52’’ marking); and E:\FR\FM\14NOP1.SGM 14NOP1 67430 Federal Register / Vol. 73, No. 221 / Friday, November 14, 2008 / Proposed Rules remove the operational limitations requirement. This proposed AD also reduces the serial number applicability from that of AD 2008–06–28 R1 due to Avidyne modifying PFDs at the factory. This condition, if not corrected, could result in airspeed/altitude mismanagement or spatial disorientation of the pilot with consequent loss of airplane control, inadequate traffic separation, or controlled flight into terrain. Relevant Service Information We have reviewed Avidyne Service Bulletin No. 601–00006–096, Revision 1, dated July 14, 2008. The service information describes procedures for: • Identifying possible Avidyne PFDs by serial number; • Identifying PFDs that have already been serviced; • Doing Avidyne PFD air data system performance verification test procedures; and • Having any Avidyne PFD that has not passed the air data system verification test or has not been factory serviced (PFD does not bears a label marked ‘‘Deviation 08–19A’’ on the exterior of the PFD near the TSO label; or a ‘‘MOD 52’’ marking) serviced. FAA’s Determination and Requirements of the Proposed AD We are proposing this AD because we evaluated all information and determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. This proposed AD would supersede AD 2008–06–28 R1 with a new AD that would retain the actions from AD 2008–06–28 R1 until the affected PFD is factory serviced; add the actions of a label or marking check, an air data system performance verification test, and (if necessary) replacement of the PFD and factory servicing of the failed PFD; and reduce the serial number applicability from that of AD 2008–06–28 R1. This proposed AD would require you to use the service information described previously to perform these actions. Differences Between This Proposed AD and the Service Information The proposed AD includes terminating action for the requirement of AD 2008–06–28 R1 to incorporate information that limits operation when certain conditions for the PFD or backup instruments exist. The requirements of this proposed AD, if adopted as a final rule, would take precedence over the provisions in the service information. Costs of Compliance We estimate that this proposed AD would affect 384 airplanes in the U.S. registry. We estimate the following costs to do the proposed serial number determination: Labor cost Parts cost Total cost per airplane Total cost on U.S. operators 1 work-hour × $80 per hour = $80 ..................................................................... Not applicable ......................... $80 $30,720 We estimate the following costs to do any necessary test and replacement that would be required based on the results of the proposed test. We have no way of determining the number of airplanes that may need this test and replacement: Labor cost Parts cost Total cost per airplane 4 work-hours × $80 per hour = $320 ..................................................................................... Not applicable ................................. $320 hsrobinson on PROD1PC76 with PROPOSALS Authority for This Rulemaking Regulatory Findings Title 49 of the United States Code specifies the FAA’s authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency’s authority. We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, ‘‘General requirements.’’ Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that the proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and 3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

You must follow the actions in the paragraphs below to determine what actions of paragraph (f) apply. Under 14 CFR 43.7, the owner/operator holding at least a private pilot certificate is allowed to do the check in paragraph (d)(1) of this AD. All other actions must be done by a certificated mechanic, unless noted differently. (1) Do a logbook check of aircraft records (previously referred to in AD 2008–06–28 R1 as ‘‘maintenance records’’) to determine if any PFD (P/Ns 700–00006–000, 700–00006– 001, 700–00006–002, 700–00006–003, or 700–00006–100) with any affected serial number listed in Avidyne Service Bulletin No. 601–00006–096, Revision 1, dated July 14, 2008, is installed. (i) If, as a result of the logbook check, you positively identify that the PFD installed does not have a serial number affected by this AD, then only paragraph (f)(5) of this AD applies to you. PO 00000 Frm 00010 Fmt 4702 Sfmt 4702 67431 (ii) If, as a result of the logbook check, you cannot positively identify the serial number of the PFD, do the visual inspection required in paragraph (d)(2) of this AD. (iii) If, as a result of the logbook check, you find any PFD installed with an affected serial number, do the actions required by paragraph (f) of this AD, including all subparagraphs as applicable. (2) If, as a result of the above logbook check, you cannot positively identify the serial number of the PFD, visually inspect any PFD (P/Ns 700–00006–000, 700–00006– 001, 700–00006–002, 700–00006–003, or 700–00006–100) for any affected serial number listed in Avidyne Service Bulletin No. 601–00006–096, Revision 1, dated July 14, 2008. (i) If, as a result of this visual inspection, you positively identify that the PFD installed does not have a serial number affected by this AD, then only paragraph (f)(5) of this AD applies to you. (ii) If, as a result of this visual inspection, you identify that the PDF installed does have a serial number affected by this AD, do the actions required in paragraph (f) of this AD, including all subparagraphs as applicable. Unsafe Condition (e) This AD results from several field reports of Avidyne PFDs displaying incorrect altitude and airspeed information and Avidyne preparing a factory service procedure that will correct the possible incorrect altitude and airspeed information displayed. We are issuing this AD to prevent certain conditions from existing when PFDs display incorrect attitude, altitude, and airspeed information. This could result in airspeed/altitude mismanagement or spatial disorientation of the pilot with consequent loss of airplane control, inadequate traffic separation, or controlled flight into terrain. Compliance (f) To address this problem, you must do the following, unless already done: E:\FR\FM\14NOP1.SGM 14NOP1 67432 Federal Register / Vol. 73, No. 221 / Friday, November 14, 2008 / Proposed Rules Compliance Procedures (1) Incorporate the operational limitations below by doing whichever of the following applies: (i) For airplanes with an airplane flight manual (AFM), pilot’s operating handbook (POH), or airplane flight manual supplement (AFMS), incorporate the language in the Appendix of this AD into the Limitations section of the AFM, POH, or AFMS (ii) For airplanes without an AFM, POH, or AFMS, do the following: (A) Incorporate the language in the Appendix of this AD into your aircraft maintenance records; and (B) Fabricate a placard (using at least 1/8-inch letters) with the following words and install the placard on the instrument panel within the pilot’s clear view: ‘‘THIS AD AND SUPERSEDED AD 2008–06–28 R1 CONTAIN LIMITATIONS REGARDING AVIDYNE PRIMARY FLIGHT DISPLAYS (PFD) AND REQUIRED INCORPORATION OF THESE LIMITATIONS INTO THE AIRCRAFT RECORDS. YOU MUST FOLLOW THESE LIMITATIONS.’’ Prior to further flight after the effective date of this AD.

Appendix to Docket No. FAA–2008–1210 Limitations Regarding Avidyne Primary Flight Displays (PFDs) Before conducting flight operations, pilots must review and be familiar with the Crosscheck Monitor section of the Avidyne Primary Flight Display Pilot’s Guide and all limitations contained in the aircraft operating handbook. As a normal practice, all pilots should be vigilant in conducting proper preflight and in-flight checks of instrument accuracy, including: • Preflight check of the accuracy of both the primary and backup altimeter against known airfield elevation and against each other. • Verification of airspeed indications consistent with prevailing conditions at startup, during taxi, and prior to takeoff. • ‘‘Airspeed alive’’ check and reasonable indications during takeoff roll. • Maintenance of current altimeter setting in both primary and backup altimeters. • Cross-check of primary and backup altimeters at each change of altimeter setting and prior to entering instrument meteorological conditions (IMC). VerDate Aug<31>2005 16:24 Nov 13, 2008 Jkt 217001 Procedures • Cross-check of primary and backup altimeters and validation against other available data, such as glideslope intercept altitude, prior to conducting any instrument approach. • Periodic cross-checks of primary and backup airspeed indicators, preferably in combination with altimeter cross-checks. For flight operations under instrument flight rules (IFR) or in conditions in which visual reference to the horizon cannot be reliably maintained (that is IMC, night operations, flight operations over water, in haze or smoke) and the pilot has reasons to suspect that any source (PFD or back-up instruments) of attitude, airspeed, or altitude is not functioning properly, flight under IFR or in these conditions must not be initiated (when condition is determined on the ground) and further flight under IFR or in these conditions is prohibited until equipment is serviced and functioning properly. Operation of aircraft not equipped with operating backup (or standby) attitude, altimeter, and airspeed indicators that are located where they are readily visible to the pilot is prohibited. Pilots must frequently scan and crosscheck flight instruments to make sure the information depicted on the PFD correlates and agrees with the information depicted on the backup instruments.

(GE) CF6–80A Series Turbofan Engines Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Notice of proposed rulemaking (NPRM). AGENCY: SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for GE CF6–80A series turbofan engines with a high-pressure turbine rotor (HPTR) stage 1 disk, part number (P/N) 9367M45G06, installed. This proposed AD would require removing any HPTR stage 1 disk, P/N 9367M45G06, before exceeding 2,075 cycles-since-new (CSN). This proposed AD results from an error by GE that incorrectly cited a cyclic life of 12,600 CSN for the HPTR stage 1 disk, P/N 9367M45G06. We are proposing this AD to prevent the HPTR stage 1 disk from exceeding its part life which could cause fatigue cracks to start and grow. These cracks could result in a possible uncontained disk failure and damage to the airplane. DATES: We must receive any comments on this proposed AD by January 13, 2009. Use one of the following addresses to comment on this proposed AD. • Federal eRulemaking Portal: Go to https://www.regulations.gov and follow the instructions for sending your comments electronically. • Mail: Docket Management Facility, U.S. Department of Transportation, 1200 New Jersey Avenue, SE., West Building Ground Floor, Room W12–140, Washington, DC 20590–0001.

Displays (Part Numbers 700-00006-000, -001, -002, -003, and -100)

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-06-
28 R1, which applies to certain Avidyne Corporation (Avidyne) Primary
Flight Displays (PFDs) (part numbers (P/Ns) 700-00006-000, -001, -002,
-003, and -100) that are installed on airplanes. AD 2008-06-28 R1
currently requires you to do a check of the maintenance records and
inspection of the PFD (if necessary) to determine if an affected serial
number PFD is installed and incorporate (if necessary) operational
limitations. Since we issued AD 2008-06-28 R1, Avidyne developed a
factory service procedure that will correct the problems on these
Avidyne PFDs and also factory serviced certain serial number PFDs.
Consequently, this proposed AD would retain the actions from AD 2008-
06-28 R1 until the affected PFD is factory serviced; add the actions of
a label or marking check, an air data system performance verification
test, and (if necessary) replacement of the PFD and factory servicing
of the failed PFD; and reduce the serial number applicability from that
of AD 2008-06-28 R1. We are proposing this AD to prevent certain
conditions from existing when PFDs display incorrect attitude,
altitude, and airspeed information. This could result in airspeed/
altitude mismanagement or spatial disorientation of the pilot with
consequent loss of airplane control, inadequate traffic separation, or
controlled flight into terrain.

DATES: We must receive comments on this proposed AD by January 13,
2009.

Discussion

Several field reports of PFDs displaying incorrect altitude and
airspeed information caused us to issue AD 2008-06-28, Amendment 39-
15440 (73 FR 15862, March 26, 2008). AD 2008-06-28 required the
following on Avidyne PFDs (P/Ns 700-00006-000, -001, -002, -003, and -
100) that are installed on airplanes:
Checking of the maintenance records and inspection of the
PFD (if necessary) to determine if an affected serial number PFD is
installed; and
If an affected serial number PFD is installed,
incorporating information that limits operation when certain conditions
for the PFD or backup instruments exist.
An incorrect serial number (SN) listed in AD 2008-06-28 caused us
to issue AD 2008-06-28 R1, Amendment 39-15468 (73 FR 19963, April 14,
2008). AD 2008-06-28 R1 corrects the incorrect SN and retains the
actions of AD-2008-06-28.
Since we issued AD 2008-06-28 R1, Avidyne has prepared a factory
service procedure that will correct the possible incorrect altitude and
airspeed information displayed on these Avidyne PFDs and received
approval for a corresponding alternative method of compliance (AMOC) to
modify certain serial number PFDs at the factory, eliminating the
unsafe condition in these units.
This proposed AD retains the actions from AD 2008-06-28 R1 until
the factory servicing is done. This proposed AD would require you to
inspect for a label marked ``Deviation 08-19A'' on the exterior of the
PFD near the TSO label or a ``MOD 52'' marking; if the label or mark is
not present, do the PFD air data system performance verification test;
if the PFD passes the test, remove the operational limitations
requirement; or if the PFD does not pass the test, remove the PFD, have
the PFD factory serviced, install a PFD that has passed the air data
system verification test or has been factory serviced (PFD bears a
label marked ``Deviation 08-19A'' on the exterior of the PFD near the
TSO label; or a ``MOD 52'' marking); and

[[Page 67430]]

remove the operational limitations requirement. This proposed AD also
reduces the serial number applicability from that of AD 2008-06-28 R1
due to Avidyne modifying PFDs at the factory.
This condition, if not corrected, could result in airspeed/altitude
mismanagement or spatial disorientation of the pilot with consequent
loss of airplane control, inadequate traffic separation, or controlled
flight into terrain.

Relevant Service Information

We have reviewed Avidyne Service Bulletin No. 601-00006-096,
Revision 1, dated July 14, 2008.
The service information describes procedures for:
Identifying possible Avidyne PFDs by serial number;
Identifying PFDs that have already been serviced;
Doing Avidyne PFD air data system performance verification
test procedures; and
Having any Avidyne PFD that has not passed the air data
system verification test or has not been factory serviced (PFD does not
bears a label marked ``Deviation 08-19A'' on the exterior of the PFD
near the TSO label; or a ``MOD 52'' marking) serviced.

FAA's Determination and Requirements of the Proposed AD

We are proposing this AD because we evaluated all information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This proposed AD
would supersede AD 2008-06-28 R1 with a new AD that would retain the
actions from AD 2008-06-28 R1 until the affected PFD is factory
serviced; add the actions of a label or marking check, an air data
system performance verification test, and (if necessary) replacement of
the PFD and factory servicing of the failed PFD; and reduce the serial
number applicability from that of AD 2008-06-28 R1. This proposed AD
would require you to use the service information described previously
to perform these actions.

Differences Between This Proposed AD and the Service Information

The proposed AD includes terminating action for the requirement of
AD 2008-06-28 R1 to incorporate information that limits operation when
certain conditions for the PFD or backup instruments exist. The
requirements of this proposed AD, if adopted as a final rule, would
take precedence over the provisions in the service information.

Costs of Compliance

We estimate that this proposed AD would affect 384 airplanes in the
U.S. registry.
We estimate the following costs to do the proposed serial number
determination:

----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80............. Not applicable................. $80 $30,720
----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do any necessary test and
replacement that would be required based on the results of the proposed
test. We have no way of determining the number of airplanes that may
need this test and replacement:

------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
4 work-hours x $80 per hour = Not applicable...... $320
$320.
------------------------------------------------------------------------

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that the proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at https://www.regulations.gov; or in person at the Docket
Management Facility between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Office (telephone (800) 647-5527)
is located at the street address stated in the ADDRESSES section.
Comments will be available in the AD docket shortly after receipt.

one of the affected serial numbers or comply with paragraph (f), all
subparagraphs, as applicable in this AD. You must follow the actions
in the paragraphs below to determine what actions of paragraph (f)
apply. Under 14 CFR 43.7, the owner/operator holding at least a
private pilot certificate is allowed to do the check in paragraph
(d)(1) of this AD. All other actions must be done by a certificated
mechanic, unless noted differently.
(1) Do a logbook check of aircraft records (previously referred
to in AD 2008-06-28 R1 as ``maintenance records'') to determine if
any PFD (P/Ns 700-00006-000, 700-00006-001, 700-00006-002, 700-
00006-003, or 700-00006-100) with any affected serial number listed
in Avidyne Service Bulletin No. 601-00006-096, Revision 1, dated
July 14, 2008, is installed.
(i) If, as a result of the logbook check, you positively
identify that the PFD installed does not have a serial number
affected by this AD, then only paragraph (f)(5) of this AD applies
to you.
(ii) If, as a result of the logbook check, you cannot positively
identify the serial number of the PFD, do the visual inspection
required in paragraph (d)(2) of this AD.
(iii) If, as a result of the logbook check, you find any PFD
installed with an affected serial number, do the actions required by
paragraph (f) of this AD, including all subparagraphs as applicable.
(2) If, as a result of the above logbook check, you cannot
positively identify the serial number of the PFD, visually inspect
any PFD (P/Ns 700-00006-000, 700-00006-001, 700-00006-002, 700-
00006-003, or 700-00006-100) for any affected serial number listed
in Avidyne Service Bulletin No. 601-00006-096, Revision 1, dated
July 14, 2008.
(i) If, as a result of this visual inspection, you positively
identify that the PFD installed does not have a serial number
affected by this AD, then only paragraph (f)(5) of this AD applies
to you.
(ii) If, as a result of this visual inspection, you identify
that the PDF installed does have a serial number affected by this
AD, do the actions required in paragraph (f) of this AD, including
all subparagraphs as applicable.

Unsafe Condition

(e) This AD results from several field reports of Avidyne PFDs
displaying incorrect altitude and airspeed information and Avidyne
preparing a factory service procedure that will correct the possible
incorrect altitude and airspeed information displayed. We are
issuing this AD to prevent certain conditions from existing when
PFDs display incorrect attitude, altitude, and airspeed information.
This could result in airspeed/altitude mismanagement or spatial
disorientation of the pilot with consequent loss of airplane
control, inadequate traffic separation, or controlled flight into
terrain.

Compliance

(f) To address this problem, you must do the following, unless
already done:

Appendix to Docket No. FAA-2008-1210 Limitations Regarding Avidyne
Primary Flight Displays (PFDs)

Before conducting flight operations, pilots must review and be
familiar with the Crosscheck Monitor section of the Avidyne Primary
Flight Display Pilot's Guide and all limitations contained in the
aircraft operating handbook.
As a normal practice, all pilots should be vigilant in
conducting proper preflight and in-flight checks of instrument
accuracy, including:
Preflight check of the accuracy of both the primary and
backup altimeter against known airfield elevation and against each
other.
Verification of airspeed indications consistent with
prevailing conditions at startup, during taxi, and prior to takeoff.
``Airspeed alive'' check and reasonable indications
during takeoff roll.
Maintenance of current altimeter setting in both
primary and backup altimeters.
Cross-check of primary and backup altimeters at each
change of altimeter setting and prior to entering instrument
meteorological conditions (IMC).
Cross-check of primary and backup altimeters and
validation against other available data, such as glideslope
intercept altitude, prior to conducting any instrument approach.
Periodic cross-checks of primary and backup airspeed
indicators, preferably in combination with altimeter cross-checks.
For flight operations under instrument flight rules (IFR) or in
conditions in which visual reference to the horizon cannot be
reliably maintained (that is IMC, night operations, flight
operations over water, in haze or smoke) and the pilot has reasons
to suspect that any source (PFD or back-up instruments) of attitude,
airspeed, or altitude is not functioning properly, flight under IFR
or in these conditions must not be initiated (when condition is
determined on the ground) and further flight under IFR or in these
conditions is prohibited until equipment is serviced and functioning
properly.
Operation of aircraft not equipped with operating backup (or
standby) attitude, altimeter, and airspeed indicators that are
located where they are readily visible to the pilot is prohibited.
Pilots must frequently scan and crosscheck flight instruments to
make sure the information depicted on the PFD correlates and agrees
with the information depicted on the backup instruments.
