Total Temperature Measuring Instruments (Turbine powered Subsonic Aircraft)

2001-07-01
CURRENT
AS793A
This standard covers three basic types of total-temperature-measuring instruments used as a means of determining the total temperature developed by adiabatic heating of the air due to motion of the aircraft through the air. Type I - Flush-type total-temperature sensor Type II - Probe-type total-temperature sensor (electrically heated) Type III - probe-type total-temperature sensor (unheated)

Temperature Instruments (Reciprocating Engine Powered Aircraft)

1969-12-01
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.

Single-Degree-of-Freedom Spring-Restrained Rate Gyros

1969-12-31
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.
