Flying a non-precision approach in the GVII is pretty easy, but setting it up correctly can be a challenge. Let's see if we can demystify the process.
Everything here is from the references shown below, with a few comments in an alternate color.
This FMS cannot fly what used to be called an "overlay" with a localizer based approach, it cannot be done. So you need to know that if you are flying an ILS, LOC, LDA, SDF, or LOC BC approach, you have not choice but to fly that thing in short range (green) data. This also means you cannot use VNAV. Yes, that is possible with some FMS, but not this one. Any other approach, so long as it is in a WGS-84 environment, can be flown in blue data.
You will manipulate the guidance panel to get to the final approach fix and again to get to the Minimum Descent Altitude / Derived Descent Altitude (MDA/DDA), and perhaps again for the Missed Approach Altitude (MAA).
The guidance panel defaults to Flight Path Angle, you can select Vertical Speed instead.
Select the MDA for a circling approach or a straight-in if not flying a Continuous Descent Final Approach where a DDA is called for. If no DDA is given, it can be computed in the GVII by adding 50 feet (maximum autopilot altitude loss) to MDA.
On the "Apr Mins" tab of the "Perf Landing" page you will see a button for Minimums Type. There is a three position radio button where you select Off, Baro, and Rad Alt. Enter your DA, MDA, or DDA in the Baro selection and if you plan on an EVS approach, enter 100 in the Rad Alt. This will give you the "Minimums" call at the DA, MDA, or DDA and the "Secondary" call at 100 feet radio altimeter height.
