MD-11, parking brake does not go off!

[Guest 413X3]

Help! My parking brake is stuck! I cannot turn it off! I have gone through the checklists, and when I went to push back using the FMC, the voice said release parking brake, but I can't! I even started all 3 engines to make sure I have hyd pressure, but nothing! I was following the quick tutorial, and had the parking brake armed before I started hyd alt pump 1, if that caused the bug its just a guess, but I can't move!!ThanksAlex

Alex,not that I think this causes the problem, however when you load the panel state for the tutorial parking brake is OFF as it should be. When you want to set it you need to turn on the HYD AUX PUMP 1 as FIRST step and then set the parking brake.Regards,Markus

Alex, you cannot disarm the parking brake by using the parking brake handle. You need to tap the toe brakes using your rudder pedals (the period key on your keyboard).Best,http://www.precisionmanuals.com/images/for...er_MD11_Vin.jpg
