x/X is taken by the simulator for increasing/decreasing zoom...
z/Z is taken by the simulator for increasing/decreasing visibility...
Not any more they won't if you use the modified keyboard.xml
the visibility code for example has been moved to key "o" etc.
Best way to see, is to fly the modified keyboard xml
All XYZ xyz keys have new codes associated now with moving view left/right up/down or forward/back.
For Example:
At start of this P51 video the pilot view was set further back so stick and pedal movements can be seen.
Also if keyboard "c" does not give you the clear air view it should on certain craft, then the Z offset forward will !
Landing the F16 with it's nose high configuration is much easier too, if you move the pilot view to help you.
