Morning all-

This is my first real post (outside of looking for expired sectional charts etc). I am nothing but an arm chair pilot trying to fly FSX by the books. I am in the process of reviewing various approach options. Currently I am learning GPS approaches.

A few questions I have come across-

1) Is there any way to link the marker annunciator to the GPS? It's nice to dial in an ILS or LOC and have the LOM/LMM give audible warning. I noticed last night that the GPS doesn't do anything when you pass the FAF. I didn't know if should just manually also set the localizer in my NAV1 just to get the marker notification

2) When flying a GPS approach, at what point would I have to turn off the GPS autopilot nav if not flying by hand? I know that GPS is a non-precision approach so I figured at the MDA I should turn it off - is this too late?

3) On a Garmin 500 - does the sensitivity of the CDI adjust automatically based on what is loaded into the flight plan? I see that it will change between en-route, terminal and approach.

That's all I have for now. Thanks in advance-

Benjamin
