Performance models are used to define the behavior of the aircraft in flight. By specifying performance models to use with each phase of the mission, you can vary the manner in which the aircraft performs based on the priorities of the mission. Aviator provides several generic aircraft performance models which users can fine tune, or import their own.
For each performance phase (such as acceleration, cruise, descend), there are several types of performance models to choose from. Built-in models default to basic models that require minimum information to calculate a trajectory. Also available are additional AGI models that allow for more detailed calculation, such as sequencing climb by altitude/fuel flow/speed. These performance models can be accessed by right-clicking in the aircraft properties window under performance models (see figure 1). Finally, advanced flight models can be built from the advanced fixed wing tool. Advanced models use aircraft propulsion and aerodynamic parameters to determine performance models. Each performance model is described in its own Help topic in this section.
Aircraft Properties allow you to view and edit available performance models. To set performance models used in a particular phase, use phase properties.
