Capabilities Covered
This lesson covers the following STK Capabilities:
- Aviator Pro
Problem Statement
The Relative Flight Path Angle strategy is a vertical plane strategy in which the aircraft flies a constant flight path angle relative to a stationary or cooperative moving object. This strategy is only available if you are using the Relative Course horizontal plane strategy.
| Field | Description |
|---|---|
| Flight Path Angle |
The flight path angle that you want the aircraft to maintain during the maneuver. |
| Anchor Alt Offset |
The height above or below the target that the aircraft will attempt to achieve. |
Maneuver Factor
The Maneuver Factor defines a dimensionless factor that influences how tightly or gently the aircraft will maneuver. At its most aggressive setting, the factor will force the strategy to achieve the specified performance values; at its most gentle setting, the factor will allow the strategy to tolerate the most deviation from those values.
Control Limits
Select a method to define the control limits (which constrain performance) of the aircraft during the maneuver.
| Field | Description |
|---|---|
| Use Accel Perf Model |
Use the control limits specified in the current acceleration performance model. |
| Specify Max Pitch Rate |
Specifically define the maximum rate at which the aircraft can climb or descend. |
Airspeed
Select a method to define the aircraft's airspeed for the maneuver from the drop-down menu and define any related properties for it.
The Min Speed Limits and Max Speed Limits properties control the behavior of STK's Aviator capability if the aircraft violates the minimum or maximum airspeed during the maneuver; select Constrain if Violated to force the aircraft to obey the limit and continue the maneuver (possibly violating physical laws), Stop if Violated to stop the maneuver at the minimum or maximum airspeed, Error if Violated to make the procedure invalid, or Ignore Limits to ignore the speed limits.
Min Absolute Altitude
Select the Use Stop Constraint check box to end the procedure if the aircraft attains the specified minimum altitude; enter the desired value in the Min Altitude field.
Max Absolute Altitude
Select the Use Stop Constraint check box to end the procedure if the aircraft attains the specified maximum altitude; enter the desired value in the Min Altitude field.
Min Altitude Rel Anchor
Select the Use Stop Constraint check box to end the procedure if the aircraft attains the specified altitude offset from the target; enter the desired value in the Min Altitude field.
Max Altitude Rel Anchor
Select the Use Stop Constraint check box to end the procedure if the aircraft attains the specified altitude offset from the target; enter the desired value in the Max Altitude field.
This strategy can be used in conjunction with the Relative Flight Path Angle strategy to model carrier operations.
