This is why Airbus inhibits the above ECAMs after 80 knots as outlined in my previous post.
Yeah but it wasn’t a “short wet runway with no stop margin, wind variable, from a ****-hole non-grooved runway”, it was HKG which is our home base. The RTO was done successfully so there’s not much to argue there.
As you said, Airbus inhibits those alerts after 80kts so it’s something that’s seen. You’d have to safely diagnose it between 100kts and rotate. That’s some proper top gun stuff if it wasn’t absolutely obvious.
If you take off, are you going to continue all the way LA if you can’t solve it?
There’s been several stories of crew continuing after seeing unreliable speed before V1 and they’ve nearly ended up in disaster. Don’t remember any of the analysis of those saying a thing about it being a good decision because of possible injuries from an evacuation.
