Yesterday, I flew back from Taiwan to Japan. The flight was delayed after we had boarded the plane.
We taxied to the runway, they revved the engines and off we were, with the normal feeling of acceleration.
Except about 10 to 15 seconds later, suddenly the engines went silent and we came to stop. A little later, the captain announced that the takeoff had been aborted because of windshear.
Fortunately, we were able to get reset and takeoff about 20 minutes later.
How often does this happen? It was a first time for me.
How long does a 787-10 Dreamliner take to reach V1? If this happened at 10 to 15 seconds (although possibly shorter, I wasn’t really paying attention), this wouldn’t be a close call, would it?
I presume that having wind shear just as the plane was taking off would not be a good thing.
I vaguely recall the tower has a gizmo (doppler radar?) to detect wind sheer. I assume this is what triggered the abort. Perhaps they’d already be aware the conditions were there and got a warning from the tower?
Most major airports have windshear detection equipiment and can issue advisories to crews. But some modern airplanes have windshear detection built into their avionics. The bizjet I work on has it, and it’s a sub-function of our ground proximity warning system. It provides two kinds of alerts based on intensity which pilots can respond to in a few scenarios, some of which are a mandatory action.
For takeoff, it depends on whether the plane has reached decision speed, assuming the warning is received during the roll. Better still, don’t initiate the takeoff. But I assume the crew in the OP’s situation got the warning after they had begun the takeoff roll.
