SimConnect FSX setting the displayed altitude indication.

Question

I've been task with creating software which will interface into flight sim 10 allowing us to alter the information the instruments display.  This is for training personel in the use of aircraft related test equipment.

Currently we are trying to get - VOR/ILS testsets (including marker beacons), Pitot/Static test set, IFF/transponder test sets.

At present we have some of this functioning through the use of FSUIPC and simconnect however we are actually shifting the aircrafts positionial data alt long etc to simulate this.

I'm trying to achieve the same thing but without shifting the aircraft around.  I have noted that SimConnect appears to be able to do this but I'm having problems.

Lets just start with one - hopefully the answer will olve the problems for the rest.

The marker beacons have a settable flag on them, but when I try it does nothing.

MARKER BEACON STATE	Marker beacon state: 0 = None 1 = Outer 2 = Middle 3 = Inner	Enum	Y
INNER MARKER	Inner marker state	Bool	Y
MIDDLE MARKER	Middle marker state	Bool	Y
OUTER MARKER	Outer marker state	Bool	Y

In this case how would I get the middle marker light to turn on without being over the actual marker?
