GI 275, old A/P and ALT preselect

[NicoN]

Q1:

Okay. I learned that the GI275 can drive old A/P, such as the Century 21.

We also have a S_TEC 60 PSS for the ALT function. It does originally ALT HOLD and a VS mode (we do not talk about the GS mode now).

Now, I saw a Video where someone demonstrated the GI 275 and was taling about an altitude bug. He said something that the GI 275 will give a "chirp" just before reaching the preselected ALT.

So, does that imply that the GI 275 can "press" the ALT button on my S-TEC PSS in order to imitate an ALT preselect?

 

 

Q2:

Can GI 275 configured as an HSI also show bearing pointers? AFAIK the Aspen does it with 2 more additional sources aqs pointers and maybe even with an ADF

My GI 275 HSI's have 2 bearing pointers. Each HSI can accept signals from 4 sources (2 VOR's and 2 GPS's). I have a Century 41 autopilot and I cannot adjust AP altitude with the 275; I have to use the UP/Down button on the AP to adjust altitude. I believe the 275 altitude bug is to alert you when you get to the set altitude whether by hand flying or autopilot.

Thank you for your answer ...

The Garmin material states that the pre-select only works with their GFC units. I was hoping it would work with my KAP 150, but no dice.
