Lets face it the new A/bus and Boeing are so foolproof you really have to make a fist of it before you will auger a new hole in th deck!
Therein lies the escape clause for all the accountants who presently drive operations at all the major airlines. They will run fatiguing rosters with inexperienced crews knowing the nice new shiny jets will scream out a warning before the !!!!! hits the N1.
and therein lies the problem!!!! we are NOT talking about shiny new airbus or boeing JETS. we are talking about 20year old SAABS which do NOT have the level of automation which protects the inexperienced. We do not have the ATC facilities who tell you where to fly, and position you on an ILS everywhere.
As good as the SAAB is, it WILL stall. it WILL Ice up. it WILL descend into terrain if you tell it to. as will a DHC-8.
