As usual that development is from Garmin. Thus Piper, Cirrus and Daher all are getting it.Piper M series certified Autoland is a giant step: M600/SLS Aircraft | HALO Safety System & Autoland | Piper
The Cirrus VisionJet already has an energy parachute for the aircraft, as do their spiston aircraft. The TBM 940 from Daher has the most capable Turboprop single engine aircraft now in service.
These are impressive advances, although they really are far simpler than are FSD in a car.
FWIW, I used to fly the TBM and a Citation 525 single pilot. That is becoming more common. I would have been wildly enthusiastic to have emergency autoland. MY regular non-pilot passenger never enjoyed emergency landing studies and practice.
I wonder if it would be wise to position FSD as similar to airplane autopilot landing assistance and Autoland. For sure that is why Elon chose the name. Sadly, non-pilots usually don't understand how autopilots are always aids, even when they actually fly a Cat IIIc approach.
