Parking brake still applied? Brakes dragging? Throttle calibrated - by which I mean does the EICAS display show that you're getting full power?

Chocks still there?

sorry what do you mean by chocks

[Captain Kevin 586]

The Boeing 747-400 has the ground service equipment available, so if you go into the FMC, you can use it. One of the items there are the chocks, which is them blocks they place right up against the tires to prevent the plane from rolling when it's parked.

If your too heavy on the breaks when taxing at speed your breaks overheat and you lose pressure in your tires making the aircraft hard to move.You have flat tires

Most likely your brakes need calibrating.

Wouldn't it be nice if P3D had the input data graph like x-plane or the input display like DCS?

Poor setup has foiled me a few times.

This is your problem. You need to read the intro manual which will explain how to resolve this.
