In the G4 simulator from Real Flight, I found a way to cause dead stick landings randomly, for practice.

Go to menu option Simulation/Flight Failures/Frequency/Always.
Then, to only allow failures for an engine out, deselect all the other options under Simulation/Flight Failures/Enable, only leaving a checkmark next to 'Kill Engine'
The 'Always' option, according to the manual, says each time you reset for a flight, something is guaranteed to go wrong, usually choosing some inconvenient time.

My question is this.

There are other failures listed which I don't understand, namely Reverse Channel and Channel Swap.

Reverse Channel sounds like the servo is turning the opposite way?? Channel Swap sounds like rudder controls throttle and vise versa for example. Does this actually happen on a radio?

What are these and how would you correct for them?
