Perhaps there are too many alarms in case of a bird strike in a modern airliner? "Hydraulic pressure LOW","Voltage in System B Out of SPEC", "Cabinets in the kitchen area Open", "and by the way,the landing gear is not down".

One would imagine there are psychology experts at Boeing and others who do nothing else all day ,but decide if one or the other alarm should be prioritised and at which volume (too low and they don't hear it, too loud and it disorients).

It is a complex subject. I think in time we realise removing the third crew member was an error.




Most of those alarms would only be shown as text on the EICAS (Boeing) or ECAM (Airbus). Very few warning systems (the most important, like GPWS, TCAS, RAAS, the engine fire alarms, and the stall warning system) are aural and/or tactile in their annunciation.

EDIT: For a practical example, low hydraulic pressure in the left-hand system in a 777 would be yellow text on the EICAS that says "HYD SYS L".


I don’t think any 737 variant has an EICAS
