keep all ice protection on...especially engine, prop, pitot/static etc
Good sentiments, but not always correct, especially not on the Saab. For instance, using the prop de-ice just because you are in the relevant temperature range has been proven to result in run-back icing. Better late than early is the message from Saab.
I'd take Jon's sentiments, but change his words to say use your de / anti - ice exactly as the manufacturer recommends.
