Final answer:
In the Instrument Landing System (ILS), the glide slope transmits a beam at right angles to the localizer beam, providing vertical guidance to aircraft on the approach to the runway.
Step-by-step explanation:
The part of the Instrument Landing System (ILS) that transmits a beam to the plane at right angles to the localizer beam at the ideal approach-path angle is known as the glide slope or glide path transmitter. The glide slope provides vertical guidance to aircraft so that they can maintain the correct altitude while on the approach to the runway. ILS is a crucial system used in aviation to assist pilots in landing an aircraft, especially in poor visibility conditions, by providing accurate lateral and vertical guidance.
