ILS/ATC Landing Issue

[TCPD5091]

@WideTracking

Today I took a beautiful crossing of Lake Superior from Thunder Bay, Ontario (CYQT) to Houghton, Michigan (KCMX). Flying a TMB 930 on an ILS route with AP and NAV on I followed a perfect route. It was a beautiful day over the lake, however, it was free of ice which I know cannot be possible yet. As expected by the plan, I passed over the airport then made a nice 180 loop lining up with the runway to land to the north.

ATC got me to the final approach altitude about 3k and quit helping. With the “green” nav lit I hit the approach mode button and nothing happened. Seeing the runway approaching I forced it into a dive while the ATC warned me about being below assigned altitude and even yelled at me to expedite my climb as my plane landed. I was on my own from there on to find a parking spot.

Did I miss doing something?

Here is a video I made on ILS approaches in the TBM back in August. Pressing APR won’t do anything until the GS is close to being centered and it will move up on the flight mode annunciator from white (arm) to green (captured). When that happens the airplane should follow the GS and you can then set missed approach altitude. For the GS to capture you have to capture the localizer first and then the GS must be captured from below (the GS deviation pointer will be at the top of the display).
