{
The XPLMPlanes APIs allow you to control the various aircraft in X-Plane,
both the user's and the sim's.
*Note*: unlike almost all other APIs in the SDK, aircraft paths are _full_
file system paths for historical reasons. You'll need to prefix all
relative paths with the X-Plane path as accessed via XPLMGetSystemPath.

XPLMSetUsersAircraft
This routine changes the user's aircraft. Note that this will reinitialize
the user to be on the nearest airport's first runway. Pass in a full path

scenery loads.

aircraft will always start with its engines running, regardless of the
user's preferences (i.e., regardless of what the dataref
`sim/operation/prefs/startup_running` says).

XPLMPlaneDrawState_t
This structure contains additional plane parameter info to be passed to
draw plane. Make sure to fill in the size of the structure field with
sizeof(XPLMDrawPlaneState_t) so that the XPLM can tell how many fields you
knew about when compiling your plugin (since more fields may be added
later).
Most of these fields are ratios from 0 to 1 for control input. X-Plane
calculates what the actual controls look like based on the .acf file for
that airplane. Note for the yoke inputs, this is what the pilot of the
plane has commanded (post artificial stability system if there were one)
and affects aelerons, rudder, etc. It is not necessarily related to the
actual position of the plane!

XPLMCountAircraft
This function returns the number of aircraft X-Plane is capable of having,
as well as the number of aircraft that are currently active. These numbers
count the user's aircraft. It can also return the plugin that is currently
controlling aircraft. In X-Plane 7, this routine reflects the number of
aircraft the user has enabled in the rendering options window.

This function returns the aircraft model for the Nth aircraft. Indices are
zero based, with zero being the user's aircraft. The file name should be
at least 256 chars in length; the path should be at least 512 chars in
length.

* EXCLUSIVE AIRCRAFT ACCESS
___________________________________________________________________________}
{
The following routines require exclusive access to the airplane APIs. Only
one plugin may have this access at a time.
}

XPLMPlanesAvailable_f
Your airplanes available callback is called when another plugin gives up
access to the multiplayer planes. Use this to wait for access to
multiplayer.
}
TYPE
XPLMPlanesAvailable_f = PROCEDURE(
inRefcon : pointer); cdecl;
{
XPLMAcquirePlanes
XPLMAcquirePlanes grants your plugin exclusive access to the aircraft. It
returns 1 if you gain access, 0 if you do not.
inAircraft - pass in an array of pointers to strings specifying the planes
you want loaded. For any plane index you do not want loaded, pass a
0-length string. Other strings should be full paths with the .acf
extension. NULL terminates this array, or pass NULL if there are no planes
you want loaded.
If you pass in a callback and do not receive access to the planes your
callback will be called when the airplanes are available. If you do receive
airplane access, your callback will not be called.

XPLMReleasePlanes
Call this function to release access to the planes. Note that if you are
disabled, access to planes is released for you and you must reacquire it.
}
PROCEDURE XPLMReleasePlanes;
cdecl; external XPLM_DLL;
{
XPLMSetActiveAircraftCount
This routine sets the number of active planes. If you pass in a number
higher than the total number of planes availables, only the total number of
planes available is actually used.
}
PROCEDURE XPLMSetActiveAircraftCount(
inCount : Integer);
cdecl; external XPLM_DLL;
{
XPLMSetAircraftModel
This routine loads an aircraft model. It may only be called if you have
exclusive access to the airplane APIs. Pass in the path of the model with
the .acf extension. The index is zero based, but you may not pass in 0
(use XPLMSetUsersAircraft to load the user's aircracft).
}

inIndex : Integer;
inAircraftPath : XPLMString);

XPLMDisableAIForPlane
This routine turns off X-Plane's AI for a given plane. The plane will
continue to draw and be a real plane in X-Plane, but will not move itself.

XPLMDrawAircraft
WARNING: Aircraft drawing via this API is deprecated and will not work in
future versions of X-Plane. Use XPLMInstance for 3-d drawing of custom
aircraft models.
This routine draws an aircraft. It can only be called from a 3-d drawing
callback. Pass in the position of the plane in OpenGL local coordinates
and the orientation of the plane. A 1 for full drawing indicates that the
whole plane must be drawn; a 0 indicates you only need the nav lights
drawn. (This saves rendering time when planes are far away.)

XPLMReinitUsersPlane
WARNING: DO NOT USE. Use XPLMPlaceUserAtAirport or
XPLMPlaceUserAtLocation.
This function recomputes the derived flight model data from the aircraft
structure in memory. If you have used the data access layer to modify the
aircraft structure, use this routine to resynchronize X-Plane; since
X-Plane works at least partly from derived values, the sim will not behave
properly until this is called.
WARNING: this routine does not necessarily place the airplane at the
airport; use XPLMSetUsersAircraft to be compatible. This routine is
provided to do special experimentation with flight models without resetting
flight.
