A Transition to Hover procedure brings an aircraft from forward flight mode to hover mode. The procedure contains one control point - the procedure site - as indicated in the diagram below.
If this procedure is interrupted, the transition will be incomplete and the aircraft will remain in hover mode.
Altitude
Define the aircraft's altitude at the end of the procedure. Select the AGL (Above Ground Level) or MSL (Mean Sea Level) reference and enter an altitude in the specified units. The altitude is constrained by the lowest ceiling value of the active performance models in the current mission phase.
Transition Options
| Field | Description |
|---|---|
| Transition into Wind | Select to define the course of the aircraft according to the wind direction. |
| Course | If the aircraft is not transitioning into the wind, define its course from north; specify a True or Magnetic north reference using the drop-down menu. |
| Smooth Transition Mode |
Select the transition mode of the aircraft at the end of the procedure from the drop-down menu:
|
| Use Max Speed When Computing Turn Radii | Select to force the aircraft maintain its cruise speed when turning, even if doing so will result in the aircraft making a turn large enough that it takes longer to complete than it would complete a slower, smaller turn. |
| Turn Factor | The Turn Factor is the maximum amount - expressed as a multiplier - that the turn radius will be increased to minimize the bank angle required to complete the turn. The factor is applied only to turns that are performed enroute to the procedure's first control point. The full circles that correspond (or are tangent) to the start/stop turns at the extended radius may not intersect if the factor is set high enough. This parameter is a limit and may not actually be achieved due to the requirement to generate an appropriate turn sequence. You can adjust the slider or enter the value manually in the box, with the minimum value being 1 and the maximum value being 10. |
| Flight Path Angle | Define the pitch angle of the flight path at the end of the procedure. |
| Radius Factor | The Radius Factor is the maximum amount - expressed as a multiplier - that the radius of a vertical curve will be increased to minimize the flight path angle required to complete it. The full circles that correspond (or are tangent) to the start/stop curves at the extended radius may not intersect if the Radius Factor is set high enough. This parameter is a limit and may not actually be achieved due to the requirement to generate an appropriate curve sequence. You can adjust the slider or enter the value manually in the box, with the minimum value being 1 and the maximum value being 10. |
Enroute Options
Enroute Options define the turning performance characteristics of the aircraft during enroute segments of the procedure.
Table - Enroute Options Parameters
Enroute Turn Direction
Enroute Turn Direction parameters define the direction that the aircraft will turn during enroute segments of the procedure.
Table - Enroute Turn Direction Parameters
Vertical Plane Options
Vertical Plane Options parameters define the flight path angle of the aircraft during enroute and arc segments of the procedure.
| Parameter | Description |
|---|---|
| Final Flight Path Angle | Define the pitch angle of the flight path at the end of the procedure. |
| Radius Factor | The Radius Factor is the maximum amount - expressed as a multiplier - that the radius of a vertical curve will be increased to minimize the flight path angle required to complete it. The full circles that correspond (or are tangent) to the start/stop curves at the extended radius may not intersect if the Radius Factor is set high enough. This parameter is a limit and may not actually be achieved due to the requirement to generate an appropriate curve sequence. You can adjust the slider or enter the value manually in the box, with the minimum value being 1 and the maximum value being 10. |
| Min Enroute FPA | Define the minimum pitch angle of the flight path during enroute segments of the procedure. |
| Max Enroute | Define the maximum pitch angle of the flight path during enroute segments of the procedure. |
