Autopilot coupled approaches

[brettt777]

I was flying with my boss the other day in a jet (L-39) that I just completed a new avionics upgrade in. We did some coupled ILS approaches to KRMG and then a precision GPS approach to KGAD. It has the usual Garmin 530 WAAS unit, a Trutrak autopilot and Aspen EFD1000s. Anyway I was wondering... I know the FSX planes have a somewhat limited Garmin GPS in alot of them. If a waypoint is selected and the autopilot is in the nav mode it follows the route, etc. Is there a way to couple it to do an ILS approach? I tried it the other day but couldn't get it o work. Did I miss something or is this not possible?

The autopilot will capture and follow an ILS... if the Nav/GPS  switch is set to Nav ... the ILS is tuned into the Nav1 ..  and the autopilot is set to the approach mode.

(and you aren't trying to intercept from too steep an angle, and you are below the glidslope)
