What must a pilot ensure concerning the aircraft's speed during an ILS approach?

During an Instrument Landing System (ILS) approach, it is critical for the pilot to ensure that the aircraft's speed matches glide slope requirements. The glide slope is part of the ILS that provides vertical guidance to the pilots, indicating the correct angle of descent towards the runway. Maintaining the proper speed is essential for several reasons.

Firstly, if the aircraft is too fast, it can lead to difficulties in controlling the descent rate and making precise adjustments as needed for the glide slope. Conversely, if the speed is too slow, there is a risk of stalling or becoming unstable during the approach, which could compromise safety.

Matching the glide slope requirements helps ensure that the aircraft enters a stable approach, allowing the pilot to maintain a correct vertical profile and achieve a safe landing. Adhering to the prescribed speeds supports the overall effectiveness of the ILS system, promoting safety and accuracy during the landing phase of flight.
