MD-11 (FS9): Autobrakes problems at rejected takeoff

Recommended Posts

I tested rejected takeoffs on 2 different computers several times, one has CH yoke+pedals, one not even a joystick.I created me a situation where the plane is almost fully loaded with passengers, cargo and fuel. I reload FS9 every time freshly before doing any tests.V1=141 kts, I abort takeoff at 140 kts, systems are set to allow a RTO (e.g. autobrakes armed at T.O., spoilers armed).I know that the procedure is to apply brakes manually, but I wanted to see what automatics do ;-)On the system without joystick, I retard throttles to idle and apply full reverse thrust. I can see the spoiler handle automatically going all the way down. The speed trend vector is very short, and I have the impression there's no wheel braking at all. When I hold the period key on the keyboard, the speed trend vector gets 3-4 times as long and the plane stops on the runway. Without manual braking, it overshoots the runway considerably.On the other system, I have the same result. I even applied manual braking with the CH pedals without success. What I didn't test yet was to apply pedal braking, release braking and re-apply.All in all, even after several tries, the brakes worked only one time, and I'm not sure if that was because I didn't load FS freshly before.Is there any visual indication that the autobrake is working?Andreas

If you have your toe brakes calibrated in FSUIPC then the autobrakes will not work most of the time for many people.You may also have a problem removing the calibration settings for the toe brakes from FSUIPC, well I did anyway, so I deleted the calibration section directly in the FSUIPC.ini with notepad.
