Using RF for wireless engine management could be implemented the following way, to avoid a few of the issues related to it being implemented.
I've got no doubt it
could be done, but it shouldn't need to be.
I think everyone has to remember that when a disk fails it will almost certainly wipe out something important. Fuel, wiring, hydraulics, control cables, structural members, other engines, the drinks trolley.. all critical systems that it could destroy.
Does that mean we should make everything twice as redundant and armour the lot? No, because the idea is that the disk should never fail in the first place!
