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

Which of the following systems are monitored by the hydraulic synoptic display?

1. Flight control surfaces

2. Electrical power distribution

3. Fuel management systems

4. Landing gear position

The correct answer is: Flight control surfaces

The hydraulic synoptic display is specifically designed to present information relating to the hydraulic systems of an aircraft, which includes the monitoring of flight control surfaces. The primary function of hydraulic systems in aviation is to manipulate the movement of various components such as ailerons, elevators, and rudders—collectively known as flight control surfaces. These components rely heavily on hydraulic pressure to operate effectively, making it crucial for pilots and maintenance personnel to monitor their status in real-time. The other options—electrical power distribution, fuel management systems, and landing gear position—are all monitored by different systems suited for their particular functions. Electrical power distribution is tracked by the aircraft’s electrical system, fuel management is handled by the fuel system displays, and landing gear position is monitored through landing gear indicators and related systems. Thus, flight control surfaces are the correct choice as they are specifically tied to the functionalities provided by the hydraulic systems.
