Oh Leady,
I think it was you that made the blunt statement along the lines, there is NO different interpretations and or definitions of these terms.
So I simply cut and pasted others in my last post (no me but from Wikipedia).
So you appear wrong - yes it appears FAA has a definition of V1, Transport Canada have a different definition, a Flight manual might have a different one and who ever wrote that other definition in Wikipedia has their definition (rightly or wrongly - they maybe from Canada with a older flight manual and thus it is correct).
Band a Lot " a person in the industry will have a good idea of the definitions (as we can see they vary!).
LeadSled "No "they" don't vary, what varies is the degree of misunderstanding, misinterpretation, and so forth."
Simple question asked simple.
Do FAA and Transport Canada have the same definition for V1?
or
Does the definition of V1 vary between FAA and Transport Canada?
