Garmin G1000 working title NXi version -Xbox platform – visual approaches not working reliably
On an intermittent basis selecting “APR” seems to turn off “GPS” mode and the G1000 enters “ROL” mode. Further the CDI changes from magenta (GPS) to green (LOC1) (see screenshot). Also the autopilot no longer navigates the aircraft to the runway threshold following the glide path. Instead you get a message on the PFD saying “no GS”. It doesn’t seem to matter where in the flight you select “APR” to elicit this problem. I have tested this issue multiple times with exactly the same aircraft and exactly the same runway approach (the second screenshot shows the destination airport and approach)!
. Sometimes things work as per normal and when you select “APR” the glide path is simply armed and then becomes active at the appropriate point and the aircraft follows the glide path down to the runway threshold. The Garmin stays in “GPS” mode for the entire duration of the flight as expected. Other times you get the behaviour described at the start of this post.
