Which statement not typically included in the initial call to air traffic services?

• A. Engine type and color of the aircraft
• B. Aircraft call sign, position/location, altitude, and the purpose of the call or request
• C. The altitude change expected
• D. Destination and ETA

Answer: (A)

The essential idea is that the initial call to air traffic services should quickly establish who you are, where you are, how high you are, and why you’re contacting them. You start with your aircraft call sign, give your current position or location relative to known points, state your altitude, and mention the purpose of the call or what you’re requesting (for example, a clearance, a flight plan update, or a change in route). You’ll often include your destination and estimated time of arrival, and if you’re planning an altitude change, you mention the new altitude or the change you’re requesting. These details let ATC identify you, know where you are, understand your intentions, and manage sequencing and separation.

Engine type and color aren’t needed for this initial exchange. ATC uses your identification, position, altitude, and requested action to provide service; engine type and color don’t affect airspace management or routing, so they aren’t typically included in the first contact.
