## Detailed Description

Base for aircraft.

Definition in file aircraft.h.

## Enumeration Type Documentation

enum AircraftSubType

An aircraft can be one ot those types.

Enumerator:

  AIR_HELICOPTER | an helicopter
  AIR_AIRCRAFT | an airplane
  AIR_SHADOW | shadow of the aircraft
  AIR_ROTOR | rotor of an helicopter

Definition at line 21 of file aircraft.h.

## Function Documentation

byte GetAircraftFlyingAltitude | ( | const Aircraft * | v | ) |

Gets the cruise altitude of an aircraft.

The cruise altitude is determined by the velocity of the vehicle and the direction it is moving

Parameters:

  | v | The vehicle. Should be an aircraft

Returns:
  Altitude in pixel units

void GetAircraftSpriteSize | ( | EngineID | engine,
|  | uint & | width,
|  | uint & | height |
| ) |  |  |

Get the size of the sprite of an aircraft sprite heading west (used for lists).

Parameters:

  | engine | The engine to get the sprite from
  | width | The width of the sprite
  | height | The height of the sprite

Definition at line 222 of file aircraft_cmd.cpp.

References Sprite::height, ST_NORMAL, and Sprite::width.

Station* GetTargetAirportIfValid | ( | const Aircraft * | v | ) |

Returns aircraft's target station if v->target_airport is a valid station with airport.

Parameters:

  | v | vehicle to get target airport for

Returns:
  pointer to target station, NULL if invalid

Updates the status of the Aircraft heading or in the station.

Parameters:

  | st | Station been updated
