quick guide...
the default stuff should be clear.. guncross, left airspeed scale ( with current G readout on top), right altitude scale
the left datablock shows, top to bottom :
- master arm status
- aircraft Mach
- max G readout
- weapon mode: LCOS,MSLS, STRF, CCIP etc
the right datablock, top to bottom :
- target range in NM ( xxx if no radar lock)
- target closure speed in knots (xxxx if no radar lock )
- range to waypoint and waypoint # (014006 = 14 nm to wp 6)
- radar altitude in feet
thats what you see in the A2A mode screenie ...
in MSLS ( missiles, short range) mode, you get a seeker FOV circle...
in NAV mode, the 2nd line of the right datablock shows 00: 00 , thats a fixed readout.. the real jet has time to go to next waypoint displayed.
