fastoad.models.performances.mission.segments.hold module¶
Class for simulating hold segment.

Bases:
fastoad.models.performances.mission.segments.base.RegulatedThrustSegment
,fastoad.models.performances.mission.segments.base.FixedDurationSegment
Class for computing hold flight segment.
Mach is considered constant, equal to Mach at starting point. Altitude is constant. Target is a specified time. The target definition indicates the time duration of the segment, independently of the initial time value.
- target: FlightPoint¶
A FlightPoint instance that provides parameter values that should all be reached at the end of
compute_from()
. Possible parameters depend on the current segment. A parameter can also be set toCONSTANT_VALUE
to tell that initial value should be kept during all segment.
- propulsion: IPropulsion¶
A IPropulsion instance that will be called at each time step.
- polar: Polar¶
The Polar instance that will provide drag data.
