<!--

This is X52.xml, the joystick config file for the Saitek X52 
USB stick and throttle.

This configuration is meant to be suitable for a generic single-engine
aircraft.

Here are some of the features of a real aircraft that we would like to
implement, and our "preferred" way of assigning them on the X52.

  Flight Controls:
    Aileron		stick L/R
    Elevator		stick fwd/aft
    Rudder		stick twist (or pedals!)
    Flaps		T3/T4
    Speedbrakes		shift T3/T4
    Pitch trim		stick upper hat
    Rudder trim		stick upper hat
    Aileron trim	throttle rocker
  Engine controls:
    Throttle		throttle
    Mixture		throttle lower rotary
    Propeller RPM	throttle thumb slider
    Carb heat (alt air)	T5/T6
    Cowl Flaps		shift T5/T6
    Fuel tank select	**not implemented**
    Mag switch		keyboard "{" and "}"
    Starter		keyboard "s"
  Other important stuff:
    gear handle up/down	T1/T2
    Overall brakes	pinky trigger
    L/R toe brakes	keyboard dot and comma
    Parking brakes	keyboard capital-B
    Push-to-talk	button (A) is a good candidate
    			also keyboard "space"
    Timer reset		MultiFunc reset
    Timer -> clock	MultiFunc function
    Autopilot disengage	**not implemented**
    Autopilot go-around	**not implemented**
  Electrical:
    Master 		**not implemented**
    Radio master 	**not implemented**
    Landing lights	**not implemented**
    Rotating beacon	**not implemented**
    Strobes		**not implemented**
    Cabin lights	**not implemented**
    Instrument lights	**not implemented**
    Circuit breakers	**not implemented**
  Instruments:
    Alternate static	**not implemented**
    Instruments on/off	mouse
    Instruments tuning	mouse or popup dialog
  Simulator and view control:
    Pan L/R Tilt Up/Dn	throttle lower hat
    Shift PoV		D-shift + throttle lower hat
    Restore std view	(C) button
    Zoom out		(B) button
    Zoom in		D-shift + (B) button

=============================================================

Here are the Unix axes observed by jsd using js_demo, and Windows axes
observed by Satia Lumbar. Mac axes are little more than guesses based
on reports of X45 behavior.  An "x" means observed to have no effect
using js_demo.  U/M/W means unix/mac/windows:

   U/ M/ W  Hardware Function		  Interpretation

   7/ 6/ 6  Stick lower hat	  +=R	  Pan View Left/Right ... or shift
   8/ 7/ 7  Stick lower hat	  +=down  Tilt View Up/Down ... or shift
   9/ 9/ 9x Green mouse		  +=up 	  [Mouse???]
  10/10/10x Green mouse		  +=away  [Mouse???]


On the Windows platform, the assignment of axes 8, 9, and 10 as
given above is only a hint, suggesting how the axes /should/ be
assigned, if the lower-level implementation ever gets around to
assigning them.

In the meantime, I have maintained cross-platform compatibility by not
assigning any critical functions to axes that don't work on the
Windows platform.

=======================

Now for the buttons.  Unix button numbers observed by jsd using
js_demo.  (Others rumored to be identical on Unix/Mac/Windows.)

Before 1 Jan 2007, all versions of plib had a bug that affecting bits
32 and 33.  The C and C++ language spec says that an out-of-range
shift (such as shifting a 32-bit word 32 or more places) produces an
/undefined/ result.  It is really not a good practice to be generating
undefined results.

I observe that on /some/ systems, bit #32 creates a conflict with bit
#0, and bit #33 creates a conflict with bit #1.  That is, they "wrap
around" the word boundary.  This means that if you roll the gray trim
wheel, it fires the gun!  If that weren't bad enough, this behavior is
not guaranteed from compiler to compiler or from hardware to hardware.
Remember, according to the C language spec, an out-of-range shift
produces an "undefined" result, so implementers can do anything they
want with it.

== Notes:

*) Note that some joystick configurations specify square-law behavior
 for some flight control axes (e.g. ailerons and/or rudder).  This is
 very unlike the behavior of flight controls on real aircraft.

 Aileron authority should be mushy at low airspeeds and crisp at high
 airspeeds ... but this should be part of the flight dynamics of the
 aircraft.  Building the correct behavior into the control stick
 configuration is neither possible nor desirable.


*) There are some aircraft in the simulator fleet that have very
 little roll damping and very little yaw damping.  (You could also say
 they have very little damping of the Dutch roll mode, but this is
 merely a natural consequence of the roll and yaw issues, not really a
 separate issue.)

 Such aircraft are vastly easier to fly with auto-coordination turned
 on.  In my opinion, you want auto-coordination on for flying an ILS
 partial panel, i.e. no DG and no AI.  
 
 For a crosswind landing, you need to have auto-coordination turned off.
 That's why the switch to do that is on the yoke.

*) This configuration does not bind the parking brake to any button on
 the joystick (or throttle).  Using the keyboard (shift-B) seems
 entirely satisfactory and more realistic than putting the /parking/
 brake button on the stick.  

*) In general, he HOTAS idea (hands on throttle and stick) should
 apply to things you need /in flight/.
