This concept is complete nonsense. I have been operating gas turbines in model aircraft since their inception over 20 years ago and now own 12 all installed in aircraft with over 2000 turbine flights logged. All are beautiful pieces of precision engineering and start (automatically) and run superbly. Mine have been extremely reliable but not without a very low rate of problems.
That said, there is the occasional flameout or mechanical failure, bearings, compressor or turbine blades being the main culprits fir mechanical failure, fuel system problems for flameouts.
To use these engines for life dependant functions in remote areas Is, in my opinion, ludicrous.
The Consequences of a main lift engine failure probably serious injury or fatal.
Totally unrealistic.
