- Contexto
- Operating into a shallow ground fog can be difficult because the approach and runway lighting patterns, which are visible through the fog as the approach descent is conducted, shorten rapidly or disappear entirely when the aircraft approaches and enters the top of the fog layer. In shallow fog, lighting cues are lost at low heights and pilots flying visually during the rapid transition from visual cues to loss of visual cues can receive a false impression of the aircraft climbing rather than descending. Reacting to the impression of aircraft climb, initiating an even steeper rate of descent from a low height without visual cues, or at best very limited visual cues, will cause the aircraft to impact terrain or the runway at a high rate of descent.
