What is the typical glideslope intercept angle for an approach?

The typical glideslope intercept angle for an approach generally ranges from 3 to 7 degrees. This range is optimal for ensuring a safe and stable descent towards the runway. A glideslope angle within this range allows pilots to have a manageable rate of descent while also ensuring adequate terrain avoidance.

Choosing an angle that is too steep may lead to difficulty in maintaining control during the approach, while an angle that is too shallow can result in a longer approach and increased fuel consumption. The glideslope is an integral part of an Instrument Landing System (ILS), designed to guide the aircraft precisely down to the runway threshold. Hence, maintaining this angle ensures both safety and efficiency in aircraft operations during landings.
