fastoad.models.performances.mission.routes module

Classes for computation of routes (i.e. assemblies of climb, cruise and descent phases).

class fastoad.models.performances.mission.routes.RangedRoute(name: str = '', _target: FlightPoint = None, climb_phases: list[FlightSequence] = <object object>, cruise_segment: CruiseSegment = <object object>, descent_phases: list[FlightSequence] = <object object>, flight_distance: float = <object object>, distance_accuracy: float = 500.0, solve_distance: bool = True)

Bases: FlightSequence

Computes a route so that it covers the specified ground distance.

The computed route will be made of:

• any number of climb phases

• one cruise segment

• any number of descent phases.

climb_phases: list[FlightSequence] = <object object>

Any number of flight phases that will occur before cruise.

cruise_segment: CruiseSegment = <object object>

The cruise phase.

descent_phases: list[FlightSequence] = <object object>

Any number of flight phases that will occur after cruise.

flight_distance: float = <object object>

Target ground distance for whole route

distance_accuracy: float = 500.0

Accuracy on actual total ground distance for the solver. In meters

solve_distance: bool = True

If True, cruise distance will be adjusted to match flight_distance

property cruise_distance

Ground distance to be covered during cruise, as set in target of cruise_segment.

property cruise_speed: tuple[str, float] | None

Type (among true_airspeed, equivalent_airspeed and mach) and value of cruise speed.

compute_from(start: FlightPoint) → 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 column names match fields of FlightPoint
