Re: TBM CRASH -ICING TEB - what would you do?
In the Lancair IV-P, I avoid visible moisture whenever icing is possible (+5c to -20c stratus or -40c cumulus). There are improving forecast maps and products at ADDS. Do a thorough preflight briefing. Especially avoid the combination of high terrain and icing. This is where most of the surprises happen. The plane is so fast and efficient, you can go around the problem, or over and above it. Plan your
route and climb accordingly. Monitor developing storms cause they don't always go where the forecasters told them to. If the terrain and icing are at your destination, wait another day or two or hire swa.com. They let you change and reuse the fare, without penalties, like the other airlines- in fact we should give SWA an award for this to set an example for the others!
I will ask for an altitude "block" to maneuver (is this a military thing-do civil aviators know about this?) ...
or just cancel IFR and do a 180. If in the goo and he won't give it to you, on the first request, squawk 7700 and start your climbing turn, 180 degrees. A little FAA phone call and/or paperwork is not worth dying for. Neither is the rental car reservation, the meeting, or the ski vacation.
Practice full power climbing 180 turn IMC on partial panel for your escape maneuver. Static discharge, with random voltage spikes through your on-board networked data can take out many Attitude displays and GPS displays, especially in composite airplanes.
a, d and e are my answers to the multiple choice below-
While the above strategy is based on military and flight test experience, I've only been scared
by icing twice:
in my Mooney over the Southern Rockies in 1984 and 2 years ago in my IV-P over the Cascades (OSH presentation 2011)
Both times it was completely unfair, unforecast, and blindsided me... fool me once...

Re: TBM CRASH -ICING TEB - what would you do?
splitting this thread from John's.
good tape. What would you have done and when?
It's a turbine with tons of climb power and boots and you've seen moderate ice before.
b) not entered IMC until you
were guaranteed a continuous climb to fl200
c)
accept clearance as given accident pilot and then violate clearance and
continue climbing once icing got beyond light, declare emergency
d) descend as soon as you saw ice
