Abstract

Currently there is no specific indicator to show the status of the touchscreen on the display. In some cases, the pilot may have manually disabled the touchscreen with a switch. A pilot does not have any visual feedback on the display to show that the touchscreen has been disabled. Solution: Provide graphical icons indicating the status of the touchscreen system.

Introduction:

A method of providing touch screen status notification to the pilot.

Background

Currently there is no specific indicator to show the status of the touchscreen on the display. In some cases, the pilot may have manually disabled the touchscreen with a switch. A pilot does not have any visual feedback on the display to show that the touchscreen has been disabled.

Technical Discussion

As touchscreen displays are being integrated into modern avionics systems, they face some challenges that conventional controls did not have. In particular, there is a lack of feedback to the user. When twisting a knob or pushing a physical button, the pilot feels a tactile response. One could look at the position of switches to ascertain the state of the switch. Haptic displays have been incorporated into personal devices but do not perform well in high vibration environments like an aircraft. The only feedback available is when a user touches an on-screen control and it behaves as expected. Currently there is no eyes-forward method of displaying the status of the touchscreen on the AFD in all situations (normal and non-normal). In some cases, the pilot may have manually disabled the touchscreen with a switch. There is no visual feedback on the display to show that the touchscreen has been disabled. Additionally, the touchscreen may be malfunctioning and there is no easy way to diagnose it.
