Answer:
The appropriate pilot action if more than one component of an ILS is unusable is to execute the missed approach procedure. The missed approach procedure is a pre-planned procedure that pilots use when they are unable to land on the intended runway. The procedure typically includes a climb to a safe altitude and a turn to a heading that will take the aircraft away from the airport.
The ILS is a precision approach system that provides pilots with guidance to land on a runway. The system consists of a localizer, which provides guidance in the horizontal direction, and a glide slope, which provides guidance in the vertical direction. If either of these components is inoperable, the ILS is no longer considered to be a precision approach system.
When more than one component of an ILS is unusable, the pilot must execute the missed approach procedure. The missed approach procedure is designed to take the aircraft away from the airport and to a safe altitude. The pilot must follow the missed approach procedure exactly to ensure the safety of the flight.
Here are some of the reasons why an ILS component may be inoperable:
The component may have malfunctioned.
The component may be out of service for maintenance.
The component may be obstructed by weather or terrain.
If an ILS component is inoperable, the pilot must be prepared to execute the missed approach procedure. The pilot should be familiar with the missed approach procedure for the airport they are flying to. The pilot should also be aware of the weather conditions at the airport and make sure that they have the proper altitude and heading to execute the missed approach procedure safely.
