Automatic Pilots (Turbine Powered Subsonic Aircraft)
2020-12-22
CURRENT
AS440B
This SAE Aerospace Standard (AS) covers automatic pilots intended for use on aircraft to automatically operate the primary and trim aerodynamic controls to maintain stable flight and/or to provide maneuvering about any of the three axes through servo control. Automatic control functions essential for primary or augmented flight control are excluded.
Standard

Directional Indicating System (Turbine Powered Subsonic Aircraft)
2020-04-14
CURRENT
ARP416B
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.
Standard

Numeral, Letter and Symbol Dimensions for Aircraft Instrument Displays
2020-04-01
CURRENT
AIR1093B
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.
Standard

Barometry for Altimeter Calibration
2020-02-20
CURRENT
AIR1075B
This SAE Aerospace Information Report (AIR) is concerned only with aspects directly relating to available accuracy. While well-designed photoelectric, inductive or capacitive readers and pressure regulators, and other accessories are highly desirable for convenience and production rate, they are considered to be outside the scope of this AIR.
Standard

Fuel and Oil Quantity Instruments
2012-08-22
CURRENT
AS405D
This Aeronautical Standard covers two basic types of instruments as follows: Type I - Float Instruments Type II - Capacitance Instruments
Standard

Temperature Instruments (Reciprocating Engine Powered Aircraft)
2008-02-16
CURRENT
AS413B
This Aerospace Standard covers two basic types of temperature instruments as follows: TYPE I: Ratiometer type, actuated by changes in electrical resistance of a temperature sensing electrical resistance element; the resistance changes being obtained by temperature changes of the temperature sensing resistance element. TYPE II: Millivoltmeter type, operated and actuated by varying E.M.F. output of a thermocouple; the varying E.M.F. input to the instrument being obtained by temperature changes of the temperature sensing thermocouple.
Standard

Flight Directors (Reciprocating Engine Powered Aircraft)
2008-02-16
CURRENT
AS420B
This Aerospace 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 pre-selected flight plan.
Standard

Rate of Climb (Vertical Speed) Indicator, Pressure Actuated (Turbine Powered Subsonic Aircraft)
2008-02-16
CURRENT
AS429
This Aerospace Standard covers four basic types of direct reading pressure actuated rate of climb (vertical speed) indicators as follows: Type I - Range 0-2000 feet per minute climb and descent Type II - Range 0-3000 feet per minute climb and descent Type III - Range 0-4000 feet per minute climb and descent Type IV - Range 0-6000 feet per minute climb and descent
Standard

Single-Degree-of-Freedom Spring-Restrained Rate Gyros
2008-02-16
CURRENT
AS1104
This specification covers that gyroscopic instrument normally defined as a "subminiature rate gyro." The rate gyro, when subjected to an angular rate about its input axis, provides an AC output voltage proportional to the angular rate. The subminiature size category generally includes gyro instruments of one (1) inch diameter or less and three and one-half (3 1/2) inches length or less. This specification defines the requirements for a subminiature spring-restrained, single-degree-of-freedom rate gyro for aircraft, missile, and spacecraft applications.
Standard

Liquid Oxygen Quantity Instruments
2008-02-16
CURRENT
ARP433A
This Aeronautical Recommended Practice covers Liquid Oxygen Quantity Indicators for use with associated Liquid Oxygen converters.
Standard

MINIMUM PERFORMANCE STANDARD FOR FUEL AND OIL QUANTITY INDICATING SYSTEM COMPONENTS
2008-02-16
CURRENT
AS8029
This AS defines components in "Capacitance Sensor" and "Non-Capacitance Sensor" type Fuel and Oil Quantity Indicating Systems. "Non-Capacitance" systems may employ any measurement technique current in the art including, but not restricted to, float, ultra-sonic and fiber optic devices. The definition of the individual components contained herein is related to the specified Total Installed System accuracy of the entire Fuel or Oil Quantity Indicating System which is a part of the airframe manufacturer's type certification approval data. This data shall be available from the subject airframe manufacturer as published in the operating manual for the aircraft type, model number and configuration. The Fuel or Oil Quantity Indicating System may incorporate optimum compensation based upon measurement of dielectric constant, temperature or density to correct for variations in fuel or oil characteristics due to temperature grade variations or additives.
