However PCM under transient glitching is safer because the aircraft can be made to behave more predictably during those instances and is therefore the preferred scheme for jets.
But I have that same benefit with PPM failsafe, so again this is not a benefit of PCM. It is a benefit of failsafe, regardless of whether you use PPM or PCM.
The system I use detects errors, discards them, sends last good information to the servo (glitch avoidance) and if the errors continue it sends my pre-programmed instructions to the servos. That is
not a description of PCM. That is a failsafe system and it is as valid on the PPM system I use as it is on a PCM system.
Too many of you are confusing PCM and failsafe as being the same thing, and thinking that failsafe is exclusive to PCM.
PCM with the error detection and failsafe memory switched off will suffer the same glitches and unpredictable flight pattern from external interference that a PPM without failsafe will do. It is failsafe that makes the difference and it can be built in to both PCM and PPM.
