Methods

`__init__`([copy_source, ...])
`as_dict`()	Convert object to dictionary.

Attributes

`copy_source`	Copy input `source` data on eval
`correct_fuel_flow`	Whether to correct fuel flow to ensure it remains within the operational limits of the aircraft type.
`downselect_met`	Downselect input MetDataset` to region around `source`.
`engine_deterioration_factor`
`eta_over_eta_b_min`	Clip the ratio of the overall propulsion efficiency to the maximum propulsion efficiency to always exceed this value.
`fill_low_altitude_with_isa_temperature`	Experimental.
`fill_low_altitude_with_zero_wind`	Experimental.
`interpolation_bounds_error`	If True, points lying outside interpolation will raise an error
`interpolation_fill_value`	Used for outside interpolation value if `interpolation_bounds_error` is False
`interpolation_localize`	Experimental.
`interpolation_method`	Interpolation method.
`interpolation_q_method`	Experimental.
`interpolation_use_indices`	Experimental.
`met_latitude_buffer`	Met latitude buffer for input to `Flight.downselect_met()`, in WGS84 coordinates.
`met_level_buffer`	Met level buffer for input to `Flight.downselect_met()`, in [\(hPa\)].
`met_longitude_buffer`	Met longitude buffer for input to `Flight.downselect_met()`, in WGS84 coordinates.
`met_time_buffer`	Met time buffer for input to `Flight.downselect_met()` Only applies when `downselect_met` is True.
`n_iter`	The number of iterations used to calculate aircraft mass and fuel flow.
`verify_met`	Call `_verify_met()` on model instantiation.

engine_deterioration_factor = 0.025¶

eta_over_eta_b_min = 0.5¶: Clip the ratio of the overall propulsion efficiency to the maximum propulsion efficiency to always exceed this value.
