Thank you so much for your contribution, PacificSet, you’re helping me a lot!
So I decided to make a test flight from EPSY (Szymany) to UMMG (Grodno) using only MFD on Daher TBM. It all looked fine from the beginning. I also choose an approach straight in MFD (ILS 17). I was assigned 7000 feet for that flight.
At one point an ATC asked me to prepare for ILS approach but via GRD transition, so I changed it in MFD. It all went well, I descended to 4000 feet and waited to catch the glideslope on final straight. But it didn’t happen. I soon realized that I’m too high, so I began to descend without autopilot to quickly get back to more-less proper final approach, but then ATC reminded me that I should stay at 4000. So I obviously missed the approach.
Is it common that the aircraft does not catch a glideslope? It was all set correctly (ILS frequency set, AP set to LOC1 & APR), but the “GS” sign never changed to green and that little green marker was below the center on the altitude screen. And again, why that ATC told me to stay at 4000 even if that meant missing the airport completely?
