The tow vehicle brakes should be used except in an emergency - then the aircraft brakes may be used. Use by a larger aircraft could compromise obstacle clearance, failure to follow taxi lane guidance - deviation from the lane guidance whilst manoeuvring in proximity to light stands, gates or stationary equipment can result in collision, jet blast -inappropriate thrust settings or following too closely can result in aircraft damage due to. What markings are required for a piston engine powered airplane? Use a good airport diagram. Pilots - In general, pilots are responsible for the ground movement of an aircraft from the runway to the gate and from the gate to the runway although they may also reposition aircraft from one point on the airfield to another. 15 to 20 knots.
