The Australian rules for turbines require a radio controlled method of shutting the turbine down independant of the ECU as well as a manual shut off valve.
I use this arrangement to do both jobs.
The servo is also set up with the failsafe to shut the fuel valve.- John.

Its the same in the UK and most of Europe.
An independent radio controlled method of shutting down the engine is not required in the UK according to BMFA or JMA. Curiously the BMFA require a manual shut off valve or fuel pump isolation switch whereas the manual valve is only a recommendation according to the JMA.
