AI Technical Summary

Technical Problem

The in-flight communication system of the trainer aircraft is not easily adjustable, causing the pilot's voice to be transmitted to another pilot's headset, which is distracting. Furthermore, operating switches or adjusting the volume requires taking one hand off the control stick, making it inconvenient to use.

Method used

The trainer aircraft adopts an in-flight communication control system based on voice acquisition threshold adjustment. The sensitivity of the voice threshold can be controlled by adjusting the HOT MIC, COLD MIC and middle positions of the rotary switch. This allows the pilot to autonomously control the communication transmission according to the sound intensity. Combined with the design of the in-flight communication connector, bus and control box, autonomous control of communication transmission can be achieved.

Benefits of technology

It improves flight safety, is easy to operate, reduces reliance on the joystick, and enhances the pilot's ease of operation and concentration.
