More advanced modern aircraft replaces these with the integrated electronic Engine Indicating and Crew Alerting System or Electronic Centralised Aircraft Monitor. An aviation annunciator panel will have a test switch to check for burned out lamps. Indicator lights are grouped together by their associated systems into various panels of lights. [1]
Master switch - Most often actually two separate switches, the battery master and the alternator master. The battery master activates a relay (sometimes called the battery contactor) which connects the battery to the aircraft's main electrical bus. The alternator master activates the alternator by applying power to the alternator field circuit ...
For example, an engine fire or loss of cabin pressure. They are enunciated with a red master warning light, a warning (red) ECAM message and a continuous repetitive chime or a specific sound or a synthetic voice. The chime can be silenced by pressing the master warning push button.
The first derivative of the A320 was the Airbus A321, also known as the Stretched A320, A320-500 and A325. [9] [25] Its launch came on 24 November 1988 after commitments for 183 aircraft from 10 customers were secured. [9] [26] The aircraft was to be a minimally changed derivative, apart from minor wing modifications and the fuselage stretch ...
An engine-indicating and crew-alerting system (EICAS) [1] is an integrated system used in modern aircraft to provide aircraft flight crew with instrumentation and crew annunciations for aircraft engines and other systems. On EICAS equipped aircraft the "recommended remedial action" is called a checklist.
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance.
The Airbus A320 family was the first airliner to feature a full glass cockpit and digital fly-by-wire flight control system. The only analogue instruments were the radio magnetic indicator, brake pressure indicator, standby altimeter and artificial horizon, the latter two being replaced by a digital integrated standby instrument system in later production models.
The engine is used on the A220, A320neo family, Embraer E-Jet E2 and the Russian Yakovlev MC-21 (although exports were stopped as part of the international sanctions during the Russian invasion of Ukraine). The Pratt & Whitney PW1000G engine family initially garnered significant interest from airlines due to its touted fuel efficiency advantages.
