How far from the runway threshold is the glide slope typically located?

The glide slope, which is part of the Instrument Landing System (ILS), is typically located at a distance of 750 to 1200 feet from the runway threshold. This distance allows for the aircraft to intercept the glide slope at a safe altitude while still being sufficiently aligned with the runway's centerline.

Placing the glide slope within this range ensures that pilots have enough time to stabilize their descent and make necessary adjustments while on approach. This specific positioning aids in providing a smooth transition into the final approach phase, contributing to a safe landing.

Understanding the glide slope's location is crucial for pilots, as it plays a significant role in approach procedures and ultimately enhances safety during the landing sequence. The options that suggest distances outside of 750 to 1200 feet would not provide the same level of effective guidance for the final approach and could contribute to increased risk during landings.
