A Basic Takeoff performance model is comprised of a simple set of parameters that define the flight characteristics of the aircraft during a takeoff.
| Field | Description |
|---|---|
| Takeoff Speed | The speed to which the aircraft accelerates on its ground roll for takeoff; 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. |
| Sea Level Ground Roll | The distance the aircraft travels along the ground while accelerating to takeoff at sea level. |
| Departure Speed | The aircraft's speed upon leaving the ground; select a reference from the drop-down menu - true airspeed (TAS), calibrated airspeed (CAS), equivalent airspeed (EAS), or Mach number. |
| 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. |
| Accel Fuel Flow | The aircraft's fuel flow rate while accelerating during takeoff. |
| Departure Fuel Flow | The aircraft's fuel flow rate at departure speed. |
