Final answer:
The correct time to request follow-on action clearance after executing a missed approach depends on the situation. In general, it is best to request it once reaching the published missed approach point. However, immediate request may be necessary in certain cases. It is not required to request clearance when established on the missed approach course.
Step-by-step explanation:
When executing a missed approach, the correct time to request follow-on action clearance depends on the situation. In general, it is best to request follow-on action clearance once reaching the published missed approach point. This is the specific point mentioned in the approach plate where the pilot is expected to start the missed approach procedure. By reaching this point, the pilot ensures that they have followed the correct path and are ready for further instructions.
However, there may be cases where the pilot needs to request follow-on action clearance immediately upon initiating the missed approach. For example, if the pilot encounters an unsafe condition or an incident during the missed approach, it is important to inform air traffic control (ATC) as soon as possible and request further instructions or assistance.
It is not required to request follow-on action clearance when established on the missed approach course. This is because once the pilot is established on the correct course and following the published missed approach procedure, further clearance from ATC may not be necessary unless there are specific instructions or circumstances that require it.
In summary, the correct time to request follow-on action clearance after executing a missed approach is typically once reaching the published missed approach point, but there may be situations where it is necessary to request it immediately upon initiating the missed approach depending on the circumstances.
