NO - the NON-NORMAL was a speed 40kts below Vref which in my book is a bit unusual in the air
BOAC, I quite agree! To me (and I am sure to you and all others) a speed 10kts below Vref
and reducing is not only "a bit unusual" but highly alarming to the the extent that I would be taking some pretty decisive action, I hope.
Rainboe, I agree with you too - whichever way you dress it up, your comments highlight the real cause.
