What do grey icons symbolize?

What do grey icons symbolize?

• A. General Aircraft
• B. Evacuation
• C. First Aid/Decompression
• D. Navigation

Answer: (A)

Grey icons are used as a neutral, general representation of the aircraft rather than a specific function. In many diagrams, color coding separates generic items from specialized systems: evacuation icons are typically bright red or orange to signal emergency action, first aid uses safety colors like green or red, and navigation icons are often blue or black. So grey denotes General Aircraft because it serves as the baseline symbol for the aircraft as a whole, not a particular procedure or subsystem.
