Section 87.483 is added under Subpart Q to read as follows: WReier-Aviles on DSKGBLS3C1PROD with PROPOSALS § 87.483 Audio visual warning systems. An audio visual warning system (AVWS) is a radar-based obstacle avoidance system. AVWS activates obstruction lighting and transmits VHF audible warnings to alert pilots of potential collisions with land-based obstructions. The continuously operating radar calculates the location, direction and groundspeed of nearby aircraft that enter one of two warning zones reasonably established by the licensee. As aircraft enter the first warning zone, the AVWS activates obstruction lighting. If the aircraft continues toward the obstacle and enters the second warning zone, the VHF radio transmits an audible warning describing the obstacle. (a) Radio determination (radar) frequencies. Frequencies authorized under § 87.475(b)(7) of this part are available for use by an AVWS. The frequency coordination requirements in § 87.475(a) of this part apply. (b) VHF audible warning frequencies. Frequencies authorized under § 87.187(j), § 87.217(a), § 87.241(b) and § 87.323(b) (excluding 121.950 MHz) of this part are available for use by an AVWS. Multiple frequencies may be authorized for an individual station, depending on need and the use of frequencies assigned in the vicinity of a proposed AVWS facility. Use of these frequencies is subject to the following limitations: (1) The output power shall not exceed¥3 dBm watts for each frequency authorized. (2) The antenna used in transmitting the audible warnings must be omni directional with a maximum gain equal to or lower than a half-wave centerfed dipole above 30 degree elevation, and a maximum gain of +5 dBi from horizontal up to 30 degrees elevation. VerDate Mar<15>2010 15:09 Mar 29, 2011 Jkt 223001 (3) The audible warning shall not exceed two seconds in duration. No more than six audible warnings may be transmitted in a single warning cycle, which shall not exceed 12 seconds in duration. An interval of at lest twenty seconds must occur between transmit cycles. * * * * * [FR Doc. 2011–7382 Filed 3–29–11; 8:45 am] BILLING CODE 6712–01–P DEPARTMENT OF TRANSPORTATION Pipeline and Hazardous Materials Safety Administration Federal Motor Carrier Safety Administration [Docket Numbers PHMSA–2010–0319 (HM–255) & FMCSA–2006–25660] RIN 2137–AE69 & 2126–AB04 Highway-Rail Grade Crossing; Safe Clearance Pipeline and Hazardous Materials Safety Administration (PHMSA), and Federal Motor Carrier Safety Administration (FMCSA), U.S. Department of Transportation (DOT).
