Avionics displays

Abstract

Avionics flight deck displays are a critical part of the aircraft avionics system. They are designed to serve a useful purpose for the crew, referred to as “intended function” by certification regulations. Regulations require flight deck equipment to be usable in both control and display aspects and to be designed to minimize human error. Historical evolution of the flight deck displays is discussed, followed by a discussion of current avionics display applications with enhanced features and functions. The optical image quality and operational environmental performance requirements as they relate to intended functions are then discussed. The display technology options are then discussed along with the unique aspects of adapting them for the flight deck use. While AMLCD is the current display technology of choice, it has evolved greatly since it was first adapted for the flight deck use for the first time about 20 years ago. Various types of AMLCDs and their design considerations for avionics applications are then discussed, along with touch screen interfaces and human factors. Potential of projection displays and the emerging AMOLED technology and flexible displays for future flight deck use is also discussed.
