There seems to be a general lack of appreciation by some younger pilots about the performance of turbine powered aircraft at higher altitudes.
Perhaps it is thought by some that 'higher is always better' when in actual fact, in many cases, this certainly is not the case.
One might read the accident report of the very
stupid performance of the relatively inexperienced pilots of a CRJ operated by Pinnacle Airlines a couple of years ago....could be a rather large wake-up call for younger hot-shot pilots...
