In what situation is use of ATC clearance necessary for missed approaches when flying under VFR?

The necessity for ATC clearance during missed approaches while operating under VFR is specifically pertinent in terminal radar service areas. In these controlled environments, ATC provides instructions to maintain separation from other aircraft and ensure safety in congested airspace.

When pilots are in terminal radar service areas, they must comply with specific air traffic control procedures, including obtaining an ATC clearance for missed approaches. This requirement enhances the safety of operations, as the ATC is monitoring and managing traffic in these busy airspaces, ensuring that the pilot can execute a missed approach safely without conflicting with other aircraft.

In contrast, near uncontrolled airports or when transitioning to IFR from VFR, clearance requirements can vary. While it is prudent always to follow ATC directives for safety, the explicit requirement for an ATC clearance during missed approaches is most critical in terminal radar service areas where the potential for traffic conflicts is greater.
