[0002] With the rapid development of urban air traffic, small aircraft will account for a higher proportion in general aviation aircraft. The display and control system of general aviation aircraft usually uses mechanical instruments or a combination of mechanical and electronic instruments to present the aircraft's attitude and navigation information to the pilot. Some relatively new aircraft are equipped with integrated electronic display and control equipment.

[0003] The cockpit using mechanical instruments usually includes instruments such as an airspeed indicator, an attitude indicator, an altimeter, a turn and slip indicator, a heading indicator, a vertical speed indicator, and an engine speed indicator.

[0004] The cockpit using integrated electronic display and control equipment usually integrates the multi-functional display and control equipment and the control panel into a single device. Aircraft manufacturers select and install 1-2 sets of this device according to the size of the cockpit of the aircraft model to achieve related functions such as primary flight display (PFD), multi-function display (MFD), automatic flight control, and flight management.

[0005] The existing modular airborne electronic instrument display control system for general aviation aircraft has the following problems:

[0006] 1. Different mechanical instruments are composed of their respective separate gauges, and each part is responsible for different functions, resulting in a large amount of maintenance work.

[0007] 2. The numerous mechanical instruments increase the workload of the pilot and are likely to distract the pilot's attention.

[0008] 3. The position of the input / control panel of the integrated electronic display and control equipment cannot be adjusted separately, resulting in limited layout of the cockpit instruments and unable to be adjusted according to the actual operating habits of the pilot.
