[jhb_airlines] Autopilot Help Please

One of the things to come out of my recent attempts to make gauges in XML  is 
the realization that in spite of using FS since version 1 on the original IBM 
 PC, there are still huge holes in my flying knowledge, which probably 
explains  why I'm a lousy pilot.
Please can the experts advise me on the following -
(a) When I switch on the autopilot, it appears that the yaw damper and wing  
leveller also become active, as in this mode the AP continues to fly the  
aircraft at its current heading and altitude. If I turn on the heading 
the wing leveller turns off, and the aircraft turns to the set heading. From  
these examples it follows that a single switch change on one autopilot 
function  can trigger off a number of consequent function setting changes. Can 
give  me a list of these inter relationships, or is it not that simple?
(b) Does the Flight Director just display the cross-hairs as a guide,  or has 
it more uses?
(c) What does the yaw damper do precisely?
(d) For a single engined prop panel, under the engine/power heading  I plan 
to include the settings for mixture, throttle, and propellor  percentages, plus 
the rpm and manifold pressure.
I assume I can just double this up for a piston engined twin, but what do I  
need to display for turboprops and jets?
(e) What's the difference between autobrakes, spoilers and air  brakes?
Alternatively, if you can point me to a useful reference site to get the  
answers, I would be grateful.
Many thanks
Frank T.
