What do all the different hinged surfaces on the 
airliner’s wings do?
David Price, Orangeville, Ontario

There are lots of moving parts to a wing besides the trailing edge flaps and leading edge slats. Ailerons are hinged rectangular parts on the aft outer portion of the wing that enable the aircraft to bank, or turn; as one aileron goes up on one wing, another simultaneously moves down on the other. Spoilers on top of the wing also play a role in the banking of an airplane but, most importantly, they reduce lift, acting as speed brakes to help slow down the aircraft or quicken the descent.

Hello Captain Doug! It has been several years since you shut down your personal blog and please know that your presence is missed. That said, ahem..., it WAS necessary. I hope you are doing well, continue to enjoy your flying and perhaps have made some progress on your weather book for pilots. Best regards,
Craig, (Cedarglen - cedarglen@peak.org)
