Question: When flying an IFR flight, what is the general regulatory requirement for reporting position over compulsory reporting points in uncontrolled airspace?

Answer options:

• Report to the nearest Flight Service Station (FSS) at any time convenient for the pilot.
• Report to ATC only if requested to do so. ✅ Transmit a position report on 126.7 MHz (enroute frequency) when passing over the fix.
• No reporting is required as it is uncontrolled airspace.

Correct answer: Transmit a position report on 126.7 MHz (enroute frequency) when passing over the fix.

Explanation: In uncontrolled airspace, when flying IFR and passing a compulsory reporting point, a position report must be transmitted on 126.7 MHz (the common enroute frequency) to advise other IFR traffic of your location and intentions. This ensures traffic awareness in the absence of ATC separation.
