If the FADEC manual mode check is too much for them I guess than they shouldn't be flying at all.
Where it was catching pilots, is they would forget the manual FADEC check at idle, roll up to 100 per cent, remember they needed to do the check, forget to go back to idle, push the switch to go to FADEC manual at 100 per cent -- and instant overspeed with an expensive repair.
This morning, I read on AvWeb where a CRJ crew went to take off in CA, advanced the power levers and had only one engine. They taxied back and reported this to maintenance. Maintenance explained they needed to start the second engine before take off. If a two pilot crew can forget to start one of their two engines, it is easy to see how a distracted pilot could make this mistake with the FADEC and it seems sensible Bell is making this change.
