I just finished a nice flight from Lhasa to Kathmandu. On the final leg I had approach ATC guiding my aircraft into the airport. As I already hit the localizer in my fully loaded MD-11 the ATC requested that I should reduce to 160 kts. I replied with “unable” as I was already clinging onto the plane because it was more a flare than a stable glide due to the low speed I already got addressed by ATC- I was expecting a stall every moment.
The ATC then replied that I would be ghosted If i wouldn’t follow instructions, so I pulled back the throttle and let the MD-11 gradually hit its limits-it was very critical.
My question is, if ATC instructs a specific speed, is that always Ground speed? I assumed so, and therefore my Airspeed was barley 130 kts, which is crazy in a fully loaded MD-11. Also I find it to be very unrealistic and it kinda ruined the approach in terms of realsism.
