Rejected Takeoffs CRJ900

[Midnight Flyer]

atis reports LLWS all the time and everybody continues to take off.

It's different, however, if you're lined up ready to go and tower reports to you that there's a windshear alert, then you wait.

Or get airspeed stagnation mid takeoff roll.... or the predictive windshear warning goes off...

Those are the real deal. LLWS is very typically way oversensitive. I typically take that with a grain of salt and just go oto high alert.
