General Authority of Civil Aviation (GACA) Aeronautical Information Publication (AIP) Practice Exam

Which of the following items should be checked for pressure in an exterior inspection?

1. Static port

2. Cockpit instruments

3. Ailerons

4. Fuel tanks

The correct answer is: Static port

The correct answer is to check the static port for pressure during an exterior inspection. The static port is an essential component that measures atmospheric pressure, which is critical for accurate altimeter and airspeed readings. Ensuring that the static port is unobstructed and functioning correctly is vital for safe flight operations, as blockages can lead to erroneous readings that can affect altitude awareness and overall situational awareness during flight. In contrast, while cockpit instruments are crucial for flight, they are typically checked during interior inspections rather than exterior ones. Ailerons are part of the flight control system and are checked for movement and security, but they do not specifically relate to pressure in the manner that the static port does. Lastly, while fuel tanks must be inspected for proper fuel levels and leaks, they do not directly involve pressure checks in the same context as the static port.
