Which is required to cancel IFR at controlled airports?

• A. Remain within class B, C, D airspace
• B. Within 10 miles of destination if in class E
• C. Must be in controlled airspace
• D. Maintains direct contact with ATC

Answer: (D)

The main idea here is that canceling an IFR clearance is an ATC-led action. At controlled airports, you must maintain direct communication with ATC to cancel IFR so they can acknowledge the cancellation and release you from IFR separation services. Once ATC confirms the cancellation, you’re free to operate under VFR, assuming weather and visibility meet VFR requirements.

This isn’t about staying in a specific airspace, a certain distance from your destination, or staying within a particular class of airspace. The critical step is obtaining ATC acknowledgment of the IFR cancellation, ensuring both you and ATC are aware you’re no longer under an IFR clearance.
