Relative Bearing

Aviator Pro

The Relative Bearing strategy is a horizontal plane strategy in which the aircraft flies to a constant relative bearing to a stationary or moving object.

Field Description
Target

Select an object in the scenario that the aircraft will target during the maneuver.

Tgt Pos/Vel Resolution

Defines the frequency of sampling of the target object's position and velocity; interpolation of the object's position will be performed between sample points.

The lowest recommended value for this property is 0.1 sec, but the lowest possible value is 0.001 sec. At the lowest value, Aviator will use the native position and velocity of the target object; this can result in dramatically slow performance when the target object is another Aviator aircraft, since STK is performing double integration calculations in such a case.

Rel Bearing

Defines the bearing relative to the target that the aircraft will achieve and maintain.

Minimum Range Defines the range from the target at which the aircraft will stop employing its guidance strategy.

Control Limits

Select a method to define the control limits (which constrain performance) of the aircraft during the maneuver.

Table - Control Limit MethodsClosed

Field Description
Use Accel Perf Model

Use the control limits specified in the current acceleration performance model.

Specify Min Turn Radius The minimum radius of a turn arc that the aircraft can perform.
Specify Max Turn Rate

The maximum rate at which the aircraft can turn.

Specify Max Horiz Accel The maximum acceleration, in the horizontal plane, that the aircraft can achieve.

If the angle rate between the aircraft and the target object exceeds the aircraft's turning rate at any point during the maneuver, then the procedure will stop. If you suspect that this is the reason that a Relative Bearing maneuver is stopping prematurely, try selecting the Specify Max Turn Rate control limit and applying a high value to see if the maneuver can then run to completion.
