Traffic advisories are NOT provided to an aircraft in which situation?

• A. When the aircraft is in Class A airspace or omission is requested by the pilot
• B. When the pilot states HAVE NUMBERS
• C. When the aircraft is in Class E airspace or omission is requested by the pilot
• D. Any time the aircraft is in VFR flight conditions

Answer: (A)

Traffic advisories are informational alerts from ATC about other known aircraft to help with situational awareness, especially for pilots flying VFR. The key idea here is that in Class A airspace, operations are exclusively IFR and ATC provides mandatory separation for those flights. Because every aircraft is under ATC control and there’s no allowance for VFR traffic inside Class A, there’s no practical need for issuing traffic advisories to the aircraft there. If a pilot asks to omit traffic advisories, that would also be a situation where advisory service isn’t provided, which fits the option described.

In contrast, in other airspace and conditions—such as Class E or during VFR operations—ATC can provide traffic advisories to aid pilots who are navigating relative traffic, and pilots may receive them unless they request otherwise. So the scenario where advisories aren’t provided is specifically tied to Class A airspace (and the potential for a pilot opting out).
