visual descent point Point in a direct approach where a 3º normal visual descent can be started to achieve a safe landing and stabilized approach to the RWY - VDP (in distance) = HAT (height over terrain) / 300 (HAT is the height of the MDA read in the approach chart of the AD) VDR VHF digital radio VFO Variable-frequency oscillator: VFR
An onboard navigation system displays a constant rate descent path to minimums. The VNAV path is computed using aircraft performance, approach constraints, weather data, and aircraft weight. The approach path is computed from the top of descent point to the end of descent waypoint, which is typically the runway or missed approach point. [1]
A concept related to the missed approach point is the visual descent point (VDP).Determination of its location is done by the designers of the instrument approach procedure, but typically this is a point on the final approach course of a non-precision approach, from which the aircraft would be able to continue its descent from the MDA to the runway threshold while maintaining a standard 3 ...
A precision approach path indicator (PAPI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. It is generally located on the left-hand side of the runway approximately 300 metres (980 ft) beyond the landing threshold of the runway.
The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.
It is the point in space where the final approach segment begins on an instrument approach. The final approach point is a point on a non-precision approach and is marked by a maltese cross symbol. In the United States, where the approach navigation aid is on the field and there is no symbol depicted, the final approach point is "where the ...
