cmdn 2 Posted April 28, 2013 Share Posted April 28, 2013 Hi, Why when you do a rejected takeoff the max autobrake is decel during just 1 second? Normally it would be decel until you press te brake? Regards Link to comment Share on other sites More sharing options...
Cheyenne Chief Pilot 829 Posted April 28, 2013 Share Posted April 28, 2013 Not sure, what's happening at your end ... were you retracting the spoilers manually, maybe? Or applying T/O thrust again? (Retarding the throttles by keystroke F1, but throttle axis still fully forward?) Or overriding autobrakes by braking manually, maybe? Link to comment Share on other sites More sharing options...
Emi 5161 Posted April 28, 2013 Share Posted April 28, 2013 The DECEL light only shows that the aircraft has a certain deceleration rate, it has nothing to do with the Autobrakes being active or not. If the aircraft reaches that deceleration rate the DECEL light comes on. If you don't have that rate the light won't come on even with the autobrakes active as far as I know.

Okey , but why during the landing I see the decel light until I press the brake? Link to comment Share on other sites More sharing options...
Cheyenne Chief Pilot 829 Posted April 28, 2013 Share Posted April 28, 2013 Are you pressing "." for manual braking? In that case you're changing the deceleration rate from the rate the autobrake system tries to maintain. As Emanuel has stated the green A/B light extinguishes, when the brake rate is different from the target rate. EDIT: Manual braking also disengages autobraking during rejected takeoff.

Actually I takeoff and about 130kts I engage the reverse , the speedbrake are deployed and I see during 2 seconds the decel green light and then there is no sign anymore ( even the blue max autobrake max) and I don't press the brake.

And during the landing I have no problem with the autobrakes it works until I press the brake! Could you tell me if during takeoff you hav the same problem as mine?

Cheyenne Chief Pilot 829 Posted April 28, 2013 Share Posted April 28, 2013 Sorry, I see both the green and the blue light remain on until my aircraft has stopped. Does your thrust actually goes into reverse? Or does it go to "forward" thrust again? Any issues with veering off the runway? Does your aircraft "bounce" on the runway? Can you hear calls from the GPWS, maybe? Link to comment Share on other sites More sharing options...

My thrust goes to reverse ,no gpws sound and no bounce. That's pretty strange. I don't understand why the ATBK works during the l anding and no during the rejected takeoff...

Cheyenne Chief Pilot 829 Posted April 28, 2013 Share Posted April 28, 2013 I can't really get a handle on this issue ... Just to give it another try: Would you mind uploading a screenshot, when the A/B have just turned off? I'd like to have a look at the upper ECAM and the ATBK switches, in particular ...

Cheyenne Chief Pilot 829 Posted April 28, 2013 Share Posted April 28, 2013 "blink" is "flash", going on and off again? Or is it about "MAX" reappearing in blue? "MAX" must reappear, that's the logic of losing ATBK. I've just checked the changelogs for HF011 and v1.04, there is no brake issue mentioned. That is, even if you missed to update or if the hotfix didn't install correctly, this issue just shouldn't be there. I'm at my wits' end now, I have to confess ...

cmdn 2 Posted April 28, 2013 Author Share Posted April 28, 2013 Okey thanks , it's maybe the new ground friction I install for FSX!? But why i'sworking correctly when I land? Link to comment Share on other sites More sharing options...
Cheyenne Chief Pilot 829 Posted April 29, 2013 Share Posted April 29, 2013 Can't explain that. But you should test the rejected T/O again with your new ground friction model disabled. Link to comment Share on other sites More sharing options...
cmdn 2 Posted April 29, 2013 Author Share Posted April 29, 2013 Okey I Will try ! Link to comment Share on other sites More sharing options...
cmdn 2 Posted April 29, 2013 Author Share Posted April 29, 2013 Ok I tried with the normal friction model but it's still not working. I have another thing to say during the rejected takeoff when I set the throttle position to idle the spoiler are deploy but the blue sign on the max autobrake disappear. No decel and no On sign...And when I set the throttle to full reverse thrust I see the blue ON and green decel during 2 secondes then it's disappear...

Regards You've confirmed already that you have v1.04 installed. The hotfix 011 changelog does not mention any brake issues fixed, but ... just to give it another try: To find out whether your HF011 is installed correctly, you might just look up the PROG page of your (left) MCDU and check whether an OPT FL is shown similar to my screenshot here (it's not about the value but the fact that the field is filled at all): Link to comment Share on other sites More sharing options...
