And another few things...., just found a few other bits that may br useful... Iwas in contact with SEMS Aerosafe, Basildon, and have a very faded fax paper, when i was possibly ferrying a mil. jet to Sweden a couple of years ago, and they also have a range of survival gear at reasonable prices.. I didn`t go in the end, and the tel .no. is faded/ illegible.
From an NTSB bulletin; operate heater on ground as moisture/ condensation in the ducting can freeze over the w/screen in flt. putting you IFR in the cockpit!
KEEP POWER ON IN THE DESCENT TO PREVENT OVERCOOLING the engines, and exercise props in descent for the same reasons..... you may also need to raise the idle speeds to prevent rundown.
It would be a good idea to make sure all u/c operating mechanisms are well purged with grease, as any water will freeze, and you may not get them down.
After t/o on a wet surface/ snow slush etc, delay getting the gear up to allow it to drain, and cycle the gear a couple of times . same with flaps ---practice flapless landings. Trimmers have also been known to freeze unless well lubricated.
