What is the typical maximum range of a glide slope signal?

The maximum range of a glide slope signal is typically around 10 nautical miles. This distance is designed to ensure that pilots can receive the glide slope information while approaching the runway during their descent. The glide slope system provides vertical guidance to maintain the correct descent path, assisting pilots in aligning with the runway accurately.

At this range, the signal is strong enough to ensure reliability and precision, which is crucial for safe landings, particularly in instrument flight conditions. Going beyond this typical range may compromise the strength and clarity of the signal, making it less effective for guiding aircraft accurately to the runway. Therefore, a 10 nautical mile range is a standard that balances coverage and signal integrity.
