Final answer:
The missed approach holding fix and the correct entry into holding are specified in the approach procedure, and can vary depending on the specific details of that procedure.
Step-by-step explanation:
In the event of a missed approach, the missed approach holding fix is not necessarily the initial approach fix or the final approach fix, but rather is a specific location that is detailed in the approach procedure for that particular airport or runway. The correct entry into holding depends on the angle at which the aircraft reaches the holding fix, which can result in one of three standard entry methods: direct entry, parallel entry, or teardrop entry. Therefore, the correct answer is C: The missed approach holding fix is specified in the approach procedure. The correct entry depends on the specific procedure.
