ANGLE-OF-ATTACK SYSTEM TEST
Special Tools
♦
Syringes - two req'd (35cc or similar)
♦
Vacuum hose (or soft plastic tubing)
♦
Modeling clay
After the AOA system has been properly calibrated in flight, this test is used to test the
AOA system plumbing integrity during every inspection and every time the wings are
removed and re-installed.
•
Using a 35cc syringe push plunger in to 7.5cc, hook-up syringe & vacuum hose to
pitot tube, turn-on EFIS, use syringe to slowly, carefully push air into pitot, look for
airspeed indication on EFIS, push-in syringe until 130 kts indicates then stop.
•
Using a second syringe push plunger in to 7.5cc. Use modeling clay to hook-up the
syringe and vacuum hose to the AOA port.
•
Pressurize the AOA port. Watch the EFIS AOA indicator. Increasing AOA port
pressure will cause the EFIS AOA indicator to move from green to red. Do not apply
more pressure than necessary to move the AOA indication into the red zone. Once
the AOA indication is in the red zone stop pushing in the syringe.
