What are the expected readings for low and high tests during the AOA test?

The expected readings for the AOA (Angle of Attack) test are crucial for ensuring that the aircraft systems are functioning correctly. The values of 10.5 units for the low test and 18.0 units for the high test indicate that the AOA system is calibrated properly and that the sensors are providing accurate data regarding the angle of attack during flight operations.

These readings are part of the pre-flight checks to ensure performance safety, as the angle of attack directly influences stall characteristics and overall aircraft handling. A reading of 10.5 units at the low test checks the sensitivity and responsiveness of the system, while the 18.0 units at the high test verifies that the system can effectively indicate higher angles of attack close to the stall threshold. This calibration is essential for maintaining safety and adhering to performance parameters during flight.

Other options present readings that are not within the acceptable range for the AOA test, reflecting potential discrepancies in system calibration or faulty readings, which would necessitate maintenance or adjustment before flight.
