All you need to know is: A/B 1--- nice and gentle for longggg runways
A/B 2---still fairly gentle for medium to long runways
A/B 3---comes in fairly quickly for normal length runways ( most commonly used setting for day to day ops )
A/B 4---comes in quickly and sometimes savagely, can cause a nose drop if you're not ready for it. used on short runways
A/B max--- never used it, but it would be a step up from 4 no doubt
A/B RTO--- never experienced it thank god ( apart from the sim ) Comes in rapidly and savagely and is hard to disconnect using the toe brakes ( actually I think it can't be using them as the pressure required is too high for lil ol me )
What do I consider a short rwy? Well anything less than 7000' probably requires A/B 4 depending on your wt and rwy conditions.
Jfk 04R/22L.....Bom 27 at max ldg wt .........Fuk 16..........are those that need A/B 4
Bom 14/32 needs A/B max.
Most others in the CX network are long enough to only need A/B 3
disclaimer: the above depend on wt, wind rwy condition and 200 or 300 or 300ER type 777
