Dash-8 yaw damper useage
Our company fly's the DHC-8 100/200/300's. For the 300's on certain runways, our takeoff/landing data asks for a flaps 15 takeoff instead of the usual flaps 5. In the -300, if we use flaps 15 we have to DIS-engage the yaw damper for the takeoff, only to re-engage it right after liftoff, clicking it on right as the wheels lift the ground for the most part. I cannot come up with a good reason as to why we cant use the yaw damper for a flaps 15 T/O in the -300. Anyone have any insight?
