This standard covers flight directors for use on aircraft to indicate to the pilot, by visual means, the correct control application for the operation of an aircraft in accordance with a preselected flight plan.
This Aeronautical Standard covers Automatic Pilots intended for use on aircraft to automatically operate the aerodynamic controls to maintain flight and/or to provide maneuvering about the three axes through servo control.
This aeronautical standard covers two basic types of instruments as follows: Type I - Pitot Pressure, straight and L-shaped, 12 and 14 volt nominal, 2 wire circuit. Type II - Pitot and Static Pressured, straight and L-shaped, 12 and 24 volt nominal, 2 wire circuit.
The purpose of this AIR is to provide recommendations for the minimum dimensions of characters and symbols used in aircraft instrument dials and panel displays as related to the conditions stated in para. 3. Numerous variables influence the legibility of aircraft instrument dial characters. This situation makes it very difficult, if not impossible, to establish an exact act of rules for optimizing all installations. Character size, one of the important considerations, can be optimized where adequate dial space exists. Usually this is not the case and the designer is faced with placing the information in a limited space while continuing to strive for error-free legibility. Appropriate minimum size requirements have been stated herein for guidance in air transport use.
This standard covers three (3) basic types of flight recorders as defined below: All requirements specified in Sections 3, 4, 5, 6 and 7 of this standard shall be applicable to all recorder types unless otherwise noted.
This recommended practice covers the requirements for gyroscopically stabilized Directional Indicating Systems, which will operate as a 1°/hour latitude corrected, free directional gyro or as a slaved gyro, magnetic compass with 1/2° accuracy.
These recommendations cover the mechanical and electrical installation and installation test procedures for automatic pilots of the type normally used in transport type aircraft. The material in this ARP does not supercede any airworthiness requirement in the Civil Air Regulations.
This standard covers stall warning instruments to provide positive warning to the pilot of an impending stall. Stall, as defined for the purpose of this standard, is the minimum steady flight speed at which the airplane is controllable.
