Aborting above V1 is heavily discouraged because usually there's a strong risk of running off the end of the runway. Of course, if you lose both engines above V1, you're really in trouble and left without much choice.
But we don't know what happened with this flight so nothing I've said here should be taken as indicative of whatever went wrong in this case. It's purely information.
[0] Which depends on many factors including the type of aircraft, loading, weather conditions, state of the runway surface - for example, wet, or iced - etc., and needs to be calculated afresh for every take off.
An airliner in the US did it and the pilot was praised for making that hard decision. Everyone walked I think. I forget which flight.
One a plane reaches v1 during takeoff, it can lose an engine and still takeoff.
It an engine was lost before v1, the takeoff would be aborted.
Here is an Airbus doing just that.
There are many factors at play and things are complicated by unexpected failures.
Thank you for the video that demonstrates a pilot aware in advance of planned "engine failure" can cope with such an event in scheduled test conditions.
The phrase "line kilometres" might indicate a smidgeon of aviation industry adjacency to some.
EDIT: Above and below comments appear to be low grade random sniping in bad faith.
There's a failure to address content and specifics and a straw assertion about "more insight than the pilots, engineers and safety regulators", a claim that was never made.
At best I have the same insights as anyone that worked with 20 airframes for a few decades and staged them about the globe in that time.
EDIT2: Symbiote has deleted their problematic reply below that the first edit was made in response to. The michaelt reply came after the reply by Symbiote and is moot, all my statements are here, undeleted and unredacted.
Everyone in the formula 1 subreddit uses jargon, none of them are F1 drivers.
The statement I made:
> Aircraft can land (in right circumstances) by gliding in sans power .. the same cannot be said for take offs.
is about having _no_ thrust power during take off.
The other statement I made acknowledged that test pilots in planned and scheduled clear weather conditions often test aircraft with mock engine failures, then pointed out that this is very different to an unexpected failure during non test flights.
Yes, sometimes these things work out alright (as per your example), other times not so much.
Landing sans power is landing with no thrust (no functioning engine).
Completing a take off with no thrust isn't possible unless the craft is a glider, a hot balloon, or a ballistic launch .. taking off with a single engine is not "taking off sans power".
Aircraft can land (in right circumstances) by gliding in sans power .. the same cannot be said for take offs.
