Definition
A cockpit avionics interface that allows the pilot to input data into, and view information from, an onboard system such as a flight management system, GPS navigator, or integrated avionics suite. It typically consists of a keypad or control panel paired with a screen that shows the entered values and system responses.
Plain English
The keypad and screen the pilot uses to type information into an onboard system and see what the system is doing.
Context Anchor
Seen in avionics descriptions, equipment lists, and aircraft system documentation.
Why Pilots Care
It streamlines entry of critical flight data and reduces head-down time by consolidating input and readout functions.
Grounding Statement
When a pilot enters a setting and then checks the screen to confirm it, the DEDS is the part that handles that exchange.
Intuition Check
Do not confuse the DEDS with the data itself. The DEDS is the interface used to enter and view the data.
Example Sentence 1
The pilot used the DEDS to enter the destination airport and review the planned route.
Example Sentence 2
While airborne, the DEDS showed updated winds and fuel remaining on the primary display.
