Definition
An aircraft equipped with electronic flight instrument displays — typically large LCD or LED screens — that replace traditional mechanical (analog) gauges. Flight, navigation, engine, and systems information are presented on integrated digital displays, usually a Primary Flight Display (PFD) and a Multi-Function Display (MFD).
Plain English
An aircraft where the instruments are shown on computer screens instead of individual round dials.
Context Anchor
Seen in automation management and cockpit familiarization for aircraft that use screens as the main instrument panel.
Derivation
Called 'glass' because the screens are made of glass, in contrast to the older 'steam gauge' panels packed with individual mechanical instruments. The nickname stuck as digital displays replaced rows of dials.
Why Pilots Care
Provides faster access to integrated information and improves situational awareness when managed correctly, but requires specific training to avoid automation surprises.
Analogy
It is like replacing several separate dashboard gauges with one organized screen that can show many kinds of information in one place.
Intuition Check
Do not read “glass cockpit” as a cockpit made of glass. In aviation, it means a cockpit that uses electronic screens for the main flight information.
Example Sentence 1
Before flying the Cirrus, she completed transition training because it was her first glass cockpit aircraft.
Example Sentence 2
In the glass cockpit aircraft the primary flight display combined attitude, airspeed, and altitude on one screen.
