On a black winter night taking off and flying over extensive fog banks in the black below I dont care what the stats say or dont say I like a second power unit
Regarding flying over weather you really need to get up to FL370 FL380 to get on top.
I have met extensive Walls of CBS down near Biarritz and around the Alps as well as over Croatia where a Turbo Prop would not have hacked it!
TBM is a great machine but very interesting is Eclipse which is turning out into a good machine under Sikorski ownership should get in and out of 800 meter strips climb to FL410 and sips fuel!
Range and payload not bad either.
Pace
