So only engines are affected, right ?
No problem with any other part of aircraft, right?
If so, it has nothing to do with ICING, but with ice crystals filling some sophisticated engine electronic inputs i.e. "Bill Gates' Windows" probes...
All other aircraft including these will not lose power due to ice crystals but because PT2 or whatever is called tube if not properly heated and filled with ice crystals will give false indication to engine control or EPR etc... but will not affect engine power, unless Auto Throttle is on.
PS
Flying 50 or even 555 NM clear of CB will not solve the problem. Any stratus cloud or any cloud at all, may contain those crystals on high altitudes.
