What is the expected action if the IAF is located along the route of flight to the holding fix?

When the Initial Approach Fix (IAF) is located along the route of flight to the holding fix, the expected action is to proceed directly to the IAF without delay. This is because the IAF serves as a point where the aircraft begins its approach to the airport and indicates the transition from the en route phase to the approach phase.

By starting the approach directly at the IAF, the pilot adheres to the standard operating procedures outlined in instrument flight rules (IFR). This is typically the most efficient and logical step, as it allows the pilot to enter the approach procedure directly and begin the descent as required, thereby maintaining the planned schedule and minimizing any unnecessary delays in the flight path.

In contrast, circling around the IAF or following the holding fix until cleared again would not be necessary and could cause delays. Requesting alternate instructions from ATC may be warranted in specific situations but is not the standard procedure when entering an IAF along the route to a holding fix.
