- 2000, National Transportation Safety Board, “1.17.4.2 Flight Crew Actions and Callouts During Nonprecision Approaches”, in Aircraft Accident Report: Controlled Flight Into Terrain, Korean Air Flight 801, Boeing 747-300, HL7468, Nimitz Hill, Guam, August 6, 1997[1], archived from the original on 18 February 2021, page 64:
- The constant angle of descent technique requires pilots to maintain a predetermined constant angle and constant rate of descent, which is generally calculated to be about 3°, except when terrain or an obstacle necessitates a steeper descent. When a ground-based glideslope signal is absent, pilots can fly the constant angle of descent approach by using flight management system (FMS) and GPS equipment for electronic guidance.
- (aviation, by extension) The vertical descent profile produced by the ILS glideslope transmitters.
- Staying on the glideslope is vitally important for a safe, stabilized approach and landing.
- (aviation) The approach path of an aircraft as it comes in to land.
