I have a question about how APMplane 3.0.0 or APM copter for that matter would behave in the following situation.
I have a plane with a 8 channel TX loss of signal failsafe. I set the failsafe to trigger a RTL and RST_MISSION_CH ‘1’ = On
If for whatever reason I had a fly away while in auto mode it would eventually lose the TX signal and the receiver would then trigger it’s failsafe and set a RTL and reset mission. Upon flying back towards me it could, it seems, regain TX signal it which case will it return to TX control so back to Auto if I didn’t change this and… if it works as I hope it would also reset the mission so it would fly to wpt 1 again right?? The idea being wpt 1 could be set at a very close distance to home. Thus even though the receiver regained TX signal and went back to auto it would, if the reset mission command was set during the original failsafe event, return to wpt 1 thus come home.
I hope it would work this way. Other wise it seems it could simply enter a continuos loop and go out of range, failsafe set to RTL, then return to the TX signal of Auto and continue again until it lost signal and then repeat all out of my control until it exhausted it fuel supply.
Am I right on this? If RTL AND reset mission is set would the plane end up at wpt 1 with this scenario?
My experience has been that once an RC RTL is initiated it will stay in RTL and fly to the home waypoint even once back in range. To change modes from RTL you need to physically move the mode switch from its last position or send a ground station command to change modes.
The reset mission channel would only apply result in the aircraft changing behavior during auto mode.

I hope that’s the case. But if I turn off the TX then turn it back on after the FS RTL was set it goes back to auto when the TX is turned back on.
If you trigger a Short Failsafe (default 1.5 seconds after a triggering condition), the plane will enter the short failsafe mode you have specified. If you are in AUTO and have a FS_SHORT_ACTN of 1, this is RTL.
If the failsafe condition ends prior to reaching the Long Failsafe time (default 20 sec after a triggering condition), the aircraft will return to its previous flight mode… in your case, AUTO. (The documentation is incorrect on this… it says the aircraft will return to AUTO, but it will actually return to the previous mode)
If you reach a long failsafe condition, the aircraft will remain in the Long Failsafe mode (1=continue with the mission, 2=RTL, 3=Glide).
If you want to prevent an RTL condition from lapsing back to the previous mode, I suppose you could set the Short Failsafe time and Long Failsafe time to be almost the same. Then the aircraft will remain locked in RTL.
In AUTO, SHORT_FS_ACTN of 1 will cause CIRCLE, not RTL. So an RTL won’t be initiated until you hit the Long Failsafe, at which point it won’t revert back to the previous mode.
