In December of 2015 Qatar Airways flew the first commercial flight of an Airbus A350 out of the United States, from JFK in New York City. The first attempt to take off was rejected, as documented at thepointsguy.com and in many articles derived from that one:
As you can see in the video above, about 18 seconds after we began rolling down JFK’s runway 22R, the aircraft self-aborted, bringing us from more than 100 mph to a loud, screeching halt in roughly 15 seconds.
The explanation given there isn't very detailed, and may not even be correct:
(Note that while Qatar representatives communicated that the plane aborted the takeoff on its own, it’s possible that the pilots may have reduced engine power manually, at which point the A350 automatically applied the brakes.)...
...Qatar’s Chief Commercial Officer, the highest ranking executive on the flight, came over to reassure us, explaining that an “indicator” was responsible for the abrupt abort. As I understand it, for some reason the A350 decided that our 11,000-foot runway was too short to support the takeoff, and the plane applied the brakes at full force — all on its own.
After about an hour and forty minutes they successfully took off from a different runway, and the flight was otherwise uneventful.
What actually happened here to cause the takeoff to be rejected? Was it aborted "automatically" as some articles have claimed or did the pilots take some action during the takeoff roll to abort it?
Obviously I'd prefer some documentation or good sources on what happened here, but it seems unlikely that there was ever a public investigation of this incident, so I'm also open to reasoning about what systems and/or procedures in the A350 (both Airbus and Qatar-specific systems and procedures of the time) are likely to cause this sort of thing, and (to help reduce and refute wild speculation), what systems likely did not cause this.
