Are you saying on a normal landing the thrust levers should be closed at 30ft? I reckon I have only seen that done two or three times ever. Would it not increase the chance of either a tail strike or hard landing if you misjudged it?
My thoughts on the Bleeds off take-off; We use a checklist to confirm proceedures that we do every single time we fly, so why would we then decide that after introducing a proceedure used rarely that the checklist is a bad idea?
