I had to laugh...then cry.
when I read the bit about the Lear 60 being so powerful, the brakes wouldn't hold
it sounds to me like that plane has weak brakes, not strong engines.
I've held the brakes on JT8d powered jets and ran up to full blast and then released prior to takeoff...brakes and engines matched just right.
picking up FOD with those big props is probably a good enough reason not to hold brakes.
AS to the NOSE UP moment. Sadly, I think the pilots, plural, both pulled back thinking they were in a TAILPLANE STALL due to ICING. It will come down to training, experience, certification of training program and pilots. AND anyone who can contact Bombardier should make it clear to all pilots that the plane is unlikely to tailplane stall. Maybe make a video to show alongside the Otter video?
I guess the Saab 340 does have a tailplane stall problem...Ready to fight the wrong war.
Sad.
