air rabbit:
I mentioned that my airline (and it seems many others according to the link to an archived pprune thread)starts the V1 call at V1 minus 5.
THIS procedure has been in use for many years. THE FAA could have unapproved it, but has not.
AND while it is very nice of you to make your post, I do not anticipate anything changing.
I remember what a big deal it was when it first came out. AND it came out last century.
I AM NOT making an argument for or against the use of this way of calling V1.
BUT it is the way that many airlines do it.
AND unless you buy my airline and change things (which would involve paperwork galore) I shall continue to say V1 starting at V1 minus 5.
JUST in case something had changed at my airline in the last day or so, I called a training captain and explained the discussion I was having on PPRUNE. He confirmed that nothing had changed and it was still V1 minus 5 to start the callout.
HE had some choice words for you, which I shall not post here out of respect for forum rules.
