Design and Research of Civil Aircraft Flap/Flap Control Lever Based on Ergonomics

Abstract

The Flap/Slat Control Lever is one of the important controls in the cockpit of a High Lift system. The design of the Flap/Slat Control Lever includes mechanical and electronic design, which needs to meet the requirements of functional interfaces, mechanical interfaces, electronic interfaces, ergonomics, airworthiness, safety, reliability and maintainability. The Flap/Slat Control Lever design is a complex process with multiple rounds of iteration and gradual progress. The overall shape, detent system design must conform to the pilot’s control habits, have good control comfort and accessibility, the shape of the knob is smooth, easy to identify, simple, smooth and accurate operation. The gate design must satisfy the airworthiness regulations. The design process needs to integrate ergonomics, sample collection, evaluation methods, probability statistics and other factors for comprehensive design.
