Their main concern was with what had caused the failure in the first place. As they climbed to altitude, the airspeed kept increasing beyond the capabilities of the airplane and the crew kept pitching the nose up.

The purpose of this knob is to compensates for actual variations from the standard atmospheric pressure and also to set to prevailing pressure at sea level. Got feedback?
