- Nota adicional1
- When an aircraft is required to fly at a certain height above ground level, the AGL refers to its average height above terrain, not above certain high features and obstacles that may be in the area of operation. If the aircraft is to fly at a fixed height above all obstacles and features, then the height is above obstruction level (AOL), not above ground level. The former may be greater than or equal to the AGL.
- Contexto
- During the initial climb, about 450 feet above ground level (a.g.l.), there was a loud noise and a loss of power associated with an uncontained failure of the 9th to 10th stage high pressure compressor spacer of the right engine.
- The conservative approaches are as follows: when the horizon is only partly over an oceanic area, plot a circle using altitude above MSL; when the horizon is entirely over land, use the above ground level (AGL) altitude, where AGL is the altitude of the reporting aircraft above the elevation of the horizon at its lowest point; and be aware that over jungle areas, mountainous terrain, or where similar signal obstructions exist, the radio detection range may be as little as one-tenth of the horizon range (in mountainous terrain or areas covered with dense vegetation, the range of the signal will be reduced considerably compared to the range over water or fl at land as discussed in section 5.6 of this Manual).
- Fly no lower than 1,000 feet above ground level (AGL) whenever possible after takeoffs and landings to avoid wires, trees, and other obstacles. For some pilots (such as aer ia l appl icators), that rule may be impractical. In these cases, helicopters should have wire strike protect ion systems to prevent emergency situat ions from occurr ing.
