Been flying this bird for a while, and found this problem happens to many around 80% of my landings.
Here's what I do on a manual landing with A/T on in SPD mode, A/P disengaged:
1.On final, I arm the spoiler and set Autobrake to 1 or 2;
2.Around,30 ft RA, I move the throttle lever on my Logitech Extreme 3 to idle.
3.Immediately after touch down, I press the F1 key then F2 key(1 or 2 hits only) on keyboard to engage a idle reverse. (I press F1 to ensure the thrust lever is idle, then press F2 for a idle reverse since the runway is usually long enough.
Then here's the problem:
When I pressed the F2 key to engage the reverse, I can see a yellow REV indication then changed to green on the EICAS, meaning the engine nacelle is IN TRANSIT -> IN REVERSE POSITION
However, only after 1 or 2 seconds, the EICAS Rev indication change to Yellow then number (thrust limit)! Which means the reverse thrust is disengaging ! I did not press any button or move lever on my joystick. And sometimes the autobrake automatically disengage it self and moved to Disarm position too and i did not apply any brake via keyboard/joystick. (the airplane is still around 100+kts )
Is anyone having the same problem? :ph34r:
