A grey icon relates to which domain?

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

Answer: (A)

Icons use color and style to signal what domain the content belongs to. A grey icon indicates material related to the general aircraft—the aircraft itself, its systems, and normal operations. That’s why the grey icon is associated with General Aircraft. Topics about evacuation focus on exits and procedures, medical topics like first aid or decompression deal with medical responses, and communications cover signaling and radios; those domains are typically represented by different icon cues, not the grey general-aircraft symbol.
