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