Plane "Creeps" Forward When I Want it to Stand Still on the Taxiway

Hi! It's been a while, but I'm back with one of my many, basic questions. This one has to do with the plane (in this case the Learjet Anniversary) "creeping" when I want it to stand still on the taxiway. AP is off. The throttle on the joystick is off. As far as I can tell, there is no power whatsoever that should cause the plane to move forward. I set the parking brake. It goes off after several seconds, and the plane slowly begins to creep forward. If I let it, the plane will gradually increase to speeds in excess of 20 kts or more. I double click on the period key to set the parking brake. Doesn't make any difference.

Any thoughts?

Sounds like an engine is running. Most jets and turboprops will creep.

By the way, the parking brake is SHFT+. (period), not double-click. All that does is apply the brakes. Twice :D

...the parking brake is SHFT+. (period), not double-click.

The default setting is Ctrl+Period.

Thanks to both of you guys. I'll try that - maybe the brake will hold it then.

As always, Bean is 100% correct. My sincerest apology. I knew the right combination, I use it all the time. I don't have any idea why I said SHFT when I meant CTRL.

Again, I apologize.

I apologize.

No need to apologize, Pat.

Show me someone who never makes a mistake and I will show you someone who never does anything.

I can get forgetful at times. Sometimes I want to apply the parking brake, and I already have.

Thing is, + is the shortcut for "Parking Brake (On/Off)"

It does not only apply the parking brake, but also releases it.

So I end up releasing it when I wanted to apply it.

I found a way around that. Pretty simple.

(period) applies the brake, and also releases the parking brake.

So when I want to apply the parking brake, I press and then I press +

First release the parking brake with the , then apply it with +

Never fails.
