I did a search thru the other autobrake problems to make sure that no one else posted this or found a solution and didn't see anything that describes the problem I am having. Here's the scenario when practicing some approaches and landings. Start of at KDFW runway 18R, load 1/3 fuel, set radio to ILS freq, set heading course in MCP, set 5 flaps, RTO, trim, FD on, no auto throttle and everything to be flown by hand, nothing done in FMC. I take off fly a circuit, capture the ILS on 18R, fully configured for landing (speed, flaps, autobrakes 2, spoiler armed,etc.), upon landing prior to touch down throttles retarded, land, reverse thrust, spoiler deploy, autobrakes work, everyting is fine. Exit 18R and taxi back for another go. Brake temps fine arounf 1.X, configure for take off, flaps, RTO, etc. Fly the same circuit and do everything exactly the same, except that on my second landing the autobrakes disarm as soon as the wheels hit the ground and I have to brake manually which of course puts the brake temps into the yellow. I have the brakes assigned to the trigger button on my X52 thru FSX and not FSUIPC. So, in essence I can not figure out why after one landing and repeating the steps from the next take off to landing why my autobrakes disable automatically as soon as the wheels touch the ground? I can see if the temps were to high, but mine are still in the white around 1.x so i'm sure thats not the problem and I am sure I am not touching the trigger button on my X52. Anyone experience this and if so how did you solve it? I've been thru the manuals and haven't seen anything that I am doing wrong on my second circuit that would make this happen.

Happened to me last night as well with the latest hotfix applied. Autobrake disarmed immediately upon landing.

I have 2916 installed but haven't tried 2922 which was uploaded after that.Sean Campbell

I have 2922. I had Autobrake 2 set as well. Disarm upon landing. This was with the 900WL. The original RTM that was released to us worked fine with the autobrakes. Taking the 800WL up in a few. Will rpt back upon landing in Oslo.

My problem is in the 800WL also, I should have mentioned that in my original post. If I remember correctly, it used to work fine in the RTM version, but after running all the updates I am not sure when it stopped working correctly.Sean Campbell

I installed the newest hotfix and noticed the same behavior, however I noticed something on my second landing that I hadn't noticed before.When I get about 30 feet off the ground and retard the throttles they go down to idle at around 22 N1 but them by themselves go back up to about 40 N1. I think this could be the reason the autobrakes are disarming themselves, and this is with the a/t turned off and I even hit the F1 key to bring it to idle but it still spools back up a bit? So, I am not sure why its working on the first landing but when I taxi back, take off and fly another circuit I get this behavior.Sean Campbell

Did you sent a ticket about this? I also experienced some strange things with the second landing.
