The DA-42 is an unknown quantity, and what is known should give you
pause... The diesel engine overheats above 11,000 feet!!!!
It is not yet certified to Part 23... We don't know how it will carry
ice, if at all - those slippery airframes and laminar flow wing
sections do not take kindly to having their shapes distorted... I
suggest we wait a while to see how the DA-42 fares in the real world..
