[snip] (d) If the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed in this section, the aircraft may be operated at that minimum speed. And the USAF has its own rules which basically mirror the FAA requirements on civilian aircraft wrt airspeed limits. Not that it's an exception rather than an exemption. SECRETARY OF THE AIR FORCE AIR FORCE INSTRUCTION 11-202, VOLUME 3 16 FEBRUARY 2005 Flying Operations GENERAL FLIGHT RULES 5.7. Aircraft Speed. 5.7.1. Supersonic Flight. The PIC will not allow the aircraft to operate at or above Mach l except as specified in AFI 13-201. Inadvertent flights above Mach will be handled IAW AFI 13-201. 5.7.2. In the NAS. The PIC will: 5.7.2.1. Not allow their aircraft to exceed 250 knots indicated airspeed (KIAS) below 10,000 ft. MSL unless the MAJCOM has approved a higher speed IAW paragraph 5.7.5., FAA Speed Authorization. 5.7.2.2. Not allow their aircraft to exceed 200 KIAS at or below 2,500 ft. AGL within 4 NMs of the primary airport of a Class C or Class D airspace area unless authorized or required by ATC, or required to maintain the minimum safe maneuvering airspeed specified in the aircraft T.O. 5.7.2.3. Not allow their aircraft to exceed 200 KIAS in the airspace underlying a Class B airspace area designated for an airport or in a VFR corridor designated through Class B airspace area, unless required to maintain the minimum safe maneuvering airspeed specified in the aircraft T.O. [snip] 5.7.5. FAA Speed Authorization. The FAA recognizes that certain military operations and training requirements cannot be met under the terms of the FAR 91.117, Aircraft Speed, and has therefore granted a speed authorization. The authorization grants an exception to aircraft having flight characteristics that preclude safe operations at speeds below 250 KIAS by providing that if the minimum safe airspeed for any particular operation is greater than the maximum speed prescribed, the aircraft may be operated at the minimum safe speed. 5.7.5.1. When the Authorization Applies. Air Force pilots may operate their aircraft below 10,000 ft. MSL, within US airspace, in excess of 250 KIAS only under the following conditions: 5.7.5.1.1. Within restricted areas. 5.7.5.1.2. Within Military Operating Areas (MOAs). 5.7.5.1.3. When operating within MAJCOM approved large-scale exercises or short-term special missions. 5.7.5.1.4. Within published IFR MTRs. 5.7.5.1.5. Within published VFR MTRs. (Exception. Aircraft will not exceed 250 KIAS on SR routes) 5.7.5.1.6. Within defined areas or routes that have been coordinated and concurred on by the proper MAJCOM and FAA regions, but have not yet been published. This provision is intended to accommodate speed requirements on an interim basis until the area/route can be published. 5.7.5.1.7. When the aircraft T.O. requires or recommends a higher speed in order to maintain safe maneuverability. If the safe maneuvering airspeed in the T.O. is listed as a range, fly the slowest speed practical in that range, based on weight and configuration. This provision is primarily to accommodate climbs/descents and terminal area operations. NOTE: Airspeeds applicable to this exemption must be published in the aircraft T.O. (Dash-1). A MAJCOM supplement or MDS specific Volume 3 does not constitute the aircraft flight manual as referenced in the FAA exemption. -- Bob Noel Looking for a sig the lawyers will hate |
