Air data computer

As all information from the sensors is transmitted electrically, routing of pitot and static pressure lines through the aircraft and associated maintenance tasks is avoided.

These devices are usually autonomous and do not require pilot input, merely sending continuously updated data to the recipient systems while the aircraft is powered up.

[10] Garrett AiResearch developed early central air data computer systems that integrated pneumatic, electrical, and electronic components.

From the late 1980s much of the USAF and USN aircraft fleets were retrofitted with the GEC Avionics Rochester-developed Standard Central Air Data Computer (SCADC).

[14][15] Aircraft fitted included the A-4 Skyhawk, A-6 Intruder, A-7 Corsair, C-5A/B Galaxy, EA-6B Prowler, F-111 Aardvark, F-4 Phantom, S-3 Viking, C-141 Starlifter, C-135 Stratolifter, C-2 Greyhound, and E-2 Hawkeye,[16] for which the company received the Queen's Award for Technological Achievement.
