Missions

Missions, i.e., flights to be simulated by AEIC, are currently represented by the simple Mission class. The Mission class represents only flights following a great circle route between origin and destination airports. It cannot represent “as-flown” trajectories from ADS-B data or other sources.

class AEIC.missions.Mission(origin, destination, departure, arrival, aircraft_type, load_factor, carrier=None, flight_number=None, origin_country=None, destination_country=None, service_type=None, engine_type=None, seat_capacity=None, flight_id=None)

Represents a single flight mission, with all relevant information for emissions calculation.

There are a set of required fields (origin, destination, departure, arrival, load factor, and aircraft type) and a set of optional fields (carrier, flight number, origin and destination country, service type, engine type, seat capacity, and flight ID). The optional fields may be None if not available, but are usually filled from fields in the OAG database.

Parameters:

  • origin (str)

  • destination (str)

  • departure (Timestamp)

  • arrival (Timestamp)

  • aircraft_type (str)

  • load_factor (float)

  • carrier (str | None)

  • flight_number (str | None)

  • origin_country (str | None)

  • destination_country (str | None)

  • service_type (str | None)

  • engine_type (str | None)

  • seat_capacity (int | None)

  • flight_id (int | None)

aircraft_type: str

Aircraft type (ICAO code).

arrival: Timestamp

Arrival time (UTC).

carrier: str | None = None

Airline (IATA code).

departure: Timestamp

Departure time (UTC).

destination: str

IATA code of destination airport.

destination_country: str | None = None

Destination country (ISO 3166-1 alpha-2 code).

property destination_position: Position

Spatial position (3-D) of destination airport.

engine_type: str | None = None

Engine type, or None if not known.

flight_id: int | None = None

Unique flight ID from mission database (if available).

flight_number: str | None = None

classmethod from_toml(data)

Create a list of Mission instances from a TOML-like dictionary.

This is used for parsing sample mission data.

Parameters:

data (dict)

Return type:

list[Mission]

property gc_distance: float

Great circle distance between departure and arrival positions (m).

property label: str

Label for mission, based on origin, destination, and aircraft type.

load_factor: float

Load factor (between 0 and 1).

origin: str

IATA code of origin airport.

origin_country: str | None = None

Origin country (ISO 3166-1 alpha-2 code).

property origin_position: Position

Spatial position (3-D) of origin airport.

seat_capacity: int | None = None

Seat capacity.

service_type: str | None = None

Service type (IATA single-letter code, documented here).
