[Embraer]

well, we have to ask what the nature of the emergency is. he said he was having a roll control issue. most of my coworkers wouldnt know what that means. as you know, the airplane just doesnt use ailerons to bank...it uses the speed brakes as well. the rate is a function of speed. he was having some form of hydraulic issue. when i checked if he wanted to minimize speed adjustments, he said affirmative. i called approach and let them know that he would probably be requesting a higher approach speed (ala, no flap landing). ...to which he, ended up requesting a no-flap landing/higher approach speed. landed safely without further incident.
