Cruise

A Cruise performance model is the same as the Basic Cruise performance model except that it allows you to specify airspeeds at multiple altitudes - rather than simply defining a ceiling altitude - using the Altitude table. Right-click an entry in the table and select Insert Before or Insert After to add rows; you cannot insert a row after the last row or before the first row. Select Delete to remove the currently selected row or Delete All Invalids to remove all invalid rows; you cannot remove the first or last rows.

Parameter Description
Default Cruise Altitude Defines the aircraft's default cruising altitude. You cannot specify an altitude below sea level (0). If a procedure is specified that requires the aircraft to fly below sea level, the performance models in effect at sea level will be applied to that procedure.
Use Aero/Propulsion Fuel Flow Select 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 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.
Altitude Displays the altitude point that is currently selected in the table.
Airspeed Type Defines the airspeed reference of the performance model - true airspeed (TAS), calibrated airspeed (CAS), equivalent airspeed (EAS), or Mach number.
Minimum Defines the minimum cruising airspeed and fuel flow.
Max Endurance Defines the cruising airspeed and fuel flow that will provided the maximum flying time possible for the aircraft.
Maximum Defines the maximum cruising airspeed and fuel flow.
Max Range Defines the cruising airspeed and fuel flow that will provided the maximum flight range possible for the aircraft.
Max Performance Defines a custom performance airspeed and fuel flow that you can use to model specific flight conditions. The values must be between the Minimum and Maximum parameters.
