Autobrake on the 777
Could anybody explain to me the difference in time delay for the autobrake on the 777?
Apart from the set decelleration rate between 1,2,3,4 and MAX, there is also a difference about when the autobrake-system actually starts operating.
I couldn't find anything in the FCOM, except for the explanation that MAX is the same as 4 upon main gear wheel spin-up, until the pitch is less than 1°. Which is not the information that I'm looking for.
Does anybody know?
