AircraftType.PreferredDescentAngle Property
Gets or sets the preferred descent angle for the aircraft.
Syntax
public System.Double PreferredDescentAngle { get; set; }Property Value
Default: 45.0
The preferred descent angle for the aircraft, in degrees below horizontal flight.
Remarks
The flight route generated by an AirRouteOperator will normally follow the terrain at a constant vertical clearance, but where the aircraft must descend from a high waypoint, the operator will try to use the preferred descent angle.
To simplify the implementation, the behavior when flying over a restricted airspace is somewhat different: the mimimum of PreferredClimbAngle and PreferredDescentAngle is used as the ideal angle both for climbing and descending, and the route can sometimes become less steep than the ideal angle due to rasterization effects.
Note that the preferred descent angle increases downward from horizontal flight.
For technical reasons, the angle must be in the range from 0° to 70°, other values will throw an exception. See also the section Limitations in Aircraft Routing.
