Takeoff

A Takeoff procedure launches an aircraft from a runway site into the air.

The procedure contains three control points - the procedure site, the Wheels Release point, and the Departure point - as indicated in the diagram below. The procedure site is defined as the runway center, and the point at which the aircraft lifts off the ground. The Wheels Release point is placed at a distance from the procedure site that is equal to the distance of the aircraft's ground roll before takeoff. The Departure point is placed at a distance from the procedure site equal to the Departure Point Range, and defines the end point of the procedure.

Takeoff Properties
Field	Description
Name	Enter a specific name for the procedure, if desired.
Use runway heading The direction that the aircraft is pointing.	Select the runway heading that the aircraft will use. The first numerical value indicates the bearing relative to magnetic north and the second value indicates the bearing relative to true north. These values are derived from the runway site definition.
Mode	Select the type of takeoff from: Normal - the aircraft pulls up off the runway and flies up to the departure altitude at the takeoff climb angle, ending the procedure in a climb-out. Since the aircraft is climbing at the end of the procedure, it may overshoot your specified altitude as it transitions to the next procedure. Fly to departure point - the aircraft pulls up off the runway and then pushes over to fly outbound to the departure range at the specified altitude; the aircraft arrives in level flight. Low transition - the procedure ends after the aircraft pulls up off the runway, without a climb. A straight line segment is inserted equivalent to the time required to roll 90 degrees between the end of the takeoff roll and the end of the procedure.
Takeoff Climb Angle	The angle at which the aircraft will climb between the procedure site and the Departure point.
Departure Alt Above Runway	The aircraft's altitude when it departs the runway. The altitude is constrained by the lowest ceiling value of the active performance models in the current mission phase.
Departure Point Range	The distance that the aircraft will travel downrange when departing the runway and before beginning the next procedure.
Runway Altitude Offset	The altitude offset above the ground level of the procedure site.
Use Terrain for Runway Altitude	Select this check box to use terrain data to define the runway's ground level altitude. STK's Aviator capability will find the highest altitude along the runway and use that value for its takeoff roll.
Hold On Deck	The duration - from the start time of the procedure - that the aircraft will wait at the Wheels Release point before beginning the takeoff.
