VTOL

The following table describes the fields that define a VTOL performance model.

Field	Description
Max Hover Altitude	The maximum altitude at which the aircraft is capable of hovering.
Use Aero/Propulsion Fuel Flow	Select this check box to use the fuel flow calculated by the aerodynamics and propulsion strategies defined in the active acceleration performance model; if the acceleration performance model is not set to calculate fuel flow, then fuel flow will not be calculated for this performance model, either.
Scale Fuel Flow by Non Std Density	Select this check box to scale the fuel flow based on the aircraft's actual altitude. If this option is disabled, the fuel flow will be calculated at the Default Cruise Altitude (if available), or at sea level.
Hover Fuel Flow	The aircraft's fuel flow rate while hovering.
Heading The direction that the aircraft is pointing. Change Maneuvers	The aircraft's performance when changing heading while hovering; enter the Rate at which the aircraft can perform the maneuver and the Transition Time - the amount of time required to transition from another maneuvering mode to this one.
Vertical Maneuvers	The aircraft's performance when performing vertical maneuvers; enter the Rate at which the aircraft can perform the maneuver and the Transition Time - the amount of time required to transition from another maneuvering mode to this one.
Translation Maneuvers	The aircraft's performance when translating while hovering; enter the Rate at which the aircraft can perform the maneuver and the Transition Time - the amount of time required to transition from another maneuvering mode to this one.
Forward Flight Mode	The aircraft's performance when transitioning to forward flight. Enter the Min Horizontal Plane Airspeed - the speed at which the aircraft can begin forward flight; select a reference from the drop-down menu - true airspeed (TAS True Airspeed: the speed that the aircraft is moving relative to the airmass that it is flying in.), calibrated airspeed (CAS Calibrated Airspeed: the speed reported by the airspeed indicator, corrected for position and instrument error.), equivalent airspeed (EAS Equivalent Airspeed: the airspeed at sea level (International Standard Atmosphere) at which the dynamic pressure is equal to the dynamic pressure at the aircraft's current true airspeed and altitude.), or Mach The ratio of the aircraft's speed and the speed of sound at the aircraft's altitude, with local atmospheric conditions. number. In addition, enter the Sea Level Transition Time - the amount of time required to transition from another maneuvering mode to this one when the aircraft is at sea level.
