'OTOH, ice in a Beech Baron, flying checks in the lee of Lake Ontario, was a fearsome problem. Scaler properties, I guess'
Been there, done that. In another life I flew checks in a Baron and picked up an astonishing amount of ice despite my best attempts to avoid it.
Other than losing a fair amount of speed (with full power) it kept flying with no problems.
One particular night I had so much all over the Aircraft I flew a zero flap approach (not wanting to change the aerodynamic shape any more) at the highest speed I dared before plunking it down on the runway.
With no heated windshield I could barely see to taxi as it was almost completely opaque.
A superb Aircraft.
Those were the days..
