scope:
This specification establishes the performance, design, and test requirements for Standby Altimeters Types I and II. These altimeters are counter pointer integrally lighted with 2-inch dial for display of pressure-altitude for the range of −1,000 to 50,000 feet or −1,000 to 70,000 feet as applicable to type. The altimeter utilizes an electrical output which varies as a function of the barometric pressure setting.
Two types of altimeters are covered by this specification:
Type Range Lighting Potentiometer Baro. output function a. I −1,000 to White (IPL) 10,000 ohms in Hg. 50,000 ft. b. II −1,000 to White 5,000 ohms Feet Altitude 70,000 ft.
