Hint:
The maximal ThrottlePos difference between parallel operating engines (due to Load sharing function) is
1,5%.
ThrottlePos output (request to EMS) is switched to be equal to the Engine Values: Speed request after
other engines clutches are disconnected (no load sharing, only one engine powers the shaft).
See Loadsharing Logical Analog outputs description for next explanation.
