Every airplane has windshear detector, its called the pilot. You compute a reference groundspeed based on your planned Vapproach speed. While flying the approach if you notice a large difference between your reference and actual groundspeed, you have a shear (assuming you've not changed your speed and the tower winds are the same).

You get to feel strong forces in the Q400 when you disengage the ap during config changes.

Wouldnt the yoke have already been back since it moves with the trim? I do not see why it would have snapped back since it would have been gradually moving back with the trim while on the AP. It certainly "kicks" sometimes when you disconnect the AP even in normal conditions as you mentioned. I wouldnt put it past it that in an abnormal situation like it was that it could have been fighting itself, and when the AP kicked off it could have gone nose up.

The AP does stink and does some crazy stuff at times. All of us that fly it have looked at it before and gone "what the heck is it doing" as it S turns down a LOC or dissengaged it only to have the controls "kick" making you again wonder "what the heck was it doing" and why was it was fighting itself?

I agree with you that its a lost art. It could be because most newer airplanes have predictive and reactive windshear equipment.

Indicated airspeed can be used just as easily. Brief airspeeds changes that are considered to indicate shear and react to them accordingly. Example: "We will go around with any gain of 20 kts or loss below Vref."

This is fantastic - thank you sir - just what I needed.
