Functional Description:
Processor accepts inputs from aircraft freestream pitot-static pressure system, angle of attack sensors, aircraft total temperature sensors, engine air inlet duct pitot-static pressure system and the altimeter barometric setting. Corrected inputs are used to 1) compute accurate air data for primary flight instruments 2) generate commands necessary to control the variable engine inlet geometry, 3) provide the afcs with pitot pressure, static pressure, and impact pressure.
Supplementary Features:
Ltech characteristics: mil-std-1750a processor, contains 1553 bus, built-in-test/3 external fail indicators, requires no cooling air, provides pressure signal outputs, provides air data to other aircraft systems.
