With all due respect, any pilot who uses discing, beta, or reverse to increase his descent needs his head examined. When was that authorized as an approved method?
How are Transport Canada and Bombardier responsible for this crew's stupidity.
Everything I've read so far on this (unfortunate and unnecessary) accident suggests this crew used this method to descend and I can't see where any of the manuals present this method as "acceptable".
I doubt TC or Bombardier can fix stupid. So,you might want to ask yourself why there's a warning at the idle detent and why would you think there needs to be a beta lockout?
Could it be that unacceptable old-wives-tales have prevailed over responsible airmanship and getting away with stupid practices haven't yet resulted in an accident, so it's okay to use this method of increasing a descent.
Wow.
