fastoad.models.performances.mission.flight.base module

Base classes for flight computation.

class fastoad.models.performances.mission.flight.base.AbstractSimpleFlight(cruise_distance: float, climb_phases: List[fastoad.models.performances.mission.base.AbstractFlightSequence], cruise_phase: fastoad.models.performances.mission.segments.cruise.CruiseSegment, descent_phases: List[fastoad.models.performances.mission.base.AbstractFlightSequence])

Bases: fastoad.models.performances.mission.base.AbstractFlightSequence

Computes a simple flight.

The computed flight will be be made of:

• any number of climb phases

• one cruise segment

• any number of descent phases.

Parameters

• cruise_distance –

• climb_phases –

• cruise_phase –

• descent_phases –

property cruise_distance

property flight_sequence

Defines the sequence as used in compute_from().

Returns

the list of IFlightPart instances for the mission.

class fastoad.models.performances.mission.flight.base.RangedFlight(flight_definition: fastoad.models.performances.mission.flight.base.AbstractSimpleFlight, flight_distance: float)

Bases: fastoad.models.performances.mission.base.IFlightPart

Computes a flight so that it covers the specified distance.

Computes the flight and adjust the cruise distance to achieve the provided flight distance.

Parameters

• flight_definition –

• flight_distance – in meters

compute_from(start: fastoad.base.flight_point.FlightPoint) → pandas.core.frame.DataFrame

Computes a flight sequence from provided start point.

Parameters

start – the initial flight point, defined for altitude, mass and speed (true_airspeed, equivalent_airspeed or mach). Can also be defined for time and/or ground_distance.

Returns

a pandas DataFrame where columns names match FlightPoint.labels
