V1 is the critical engine failure recognition speed or takeoff decision speed.
Band a lot,
The above is quite simply wrong, a very dangerous "definition", as the accident record so clearly shows, and inconsistent with the further definitions you have posted.
You have even chosen to ignore the history I posted, as it does not correspond with your learned errors.
I am quite simply wasting my time with any further attempts to correct your misconceptions, I just hope you are not, and never likely to be, the Captain of a HICAP RPT aircraft, or any aircraft where a V1 is likely to be critical to the risk management of flight operations.
Tootle pip!!
