Hi All, So as per the FCOM another way to disengage the autobrake system is to move the speedbrake lever to the down detent. Guess what? Our 737 simulates just that! Similar things like this continue to impress me! Thanks Carl Beeby

Thanks wasnt aware of that. Will use that technique.

Hi Jeff I first tried it to see if it behaved like this - I now find it usefull to get over the FSX limitation of having to hit the brakes twice to disengage! Carl

That's good info, thanks Carl, will try it on my next flight!

Why not just turn the autobrake knob to off ??

Because this will not disengage the autobrake system.

Yes it does. FCOM Vol 2 14.20:

Autobrake – Disarm The pilots may disarm the autobrake system by moving the selector switch to theOFF position.

Yup! My mistake. U're right!

Isn't the simplest way just to deploy the footbrakes? Your feet should be on them and keeping the spoilers deployed seems to be common practice. I often see the aircraft turning off the active with the speedbrakes still in their deployed position. Off to read the FCOM. EDIT: yes, the manual brakes trip the autobrake off on RTO or landing.

I agree somehow the foot brake method would seem the most logical.

I agree - the foot brake method is the most logical. Was just amazing to see this relatively small detail of the autobrake system replicated in the sim! I'm sure there are lots more things to find! Carl

Yes, it is a real gold mine... I havde been reading through a real world FCOM and everything I have looked up in there works as it should in the NGX. Amazing stuff! Andrew
