23## @package mlx.fsuipc
24#
25# The module towards FSUIPC.
26#
27# This module implements the simulator interface to FSUIPC.
28#
29# The \ref Handler class is thread handling the FSUIPC requests. It can be
30# given read, periodic read and write, requests, that are executed
31# asynchronously, and a callback function is called with the result. This class
32# is used internally within the module.
33#
34# The \ref Simulator class is the actual interface to the flight simulator, and
35# an instance of it is returned by \ref mlx.fs.createSimulator. This object can
36# be used to connect to the simulator and disconnect from it, to query various
37# data and to start and stop the monitoring of the data.
38#
39# \ref AircraftModel is the base class of the aircraft models. A "model" is a
40# particular implementation of an aircraft, such as the PMDG Boeing 737NG in
41# Flight Simulator 2004. Since each type and each model has its peculiarities
42# (e.g. the different engine and fuel tank configurations), each aircraft type
43# has a generic model, that should work for most of the time. However, certain
44# models may implement various controls, gauges, etc. differently, and such
45# peculiarites can be handled in a specific subclass of \ref
46# AircraftModel. These subclasses should be registered as special ones, and if
47# the simulator detects that the aircraft's model became known or has changed,
48# it will check these special models before resorting to the generic ones.
49#
50# The models are responsible also for querying certain parameters, such as the
51# fuel tank configuration. While ideally it should be specific to a type only,
52# it is possible that the model contains different tanks, in which case some
53# tricks may be needed. See the \ref DC3Model "DC-3 (Li-2)" aircraft as an
54# example.
