But theres another, far more likely danger to think about. The term vehicle includes aircraft being taxied under their own power by a non-pilot, or being towed with no intention for flight. The function of any flight deck occupant(s) is likely to be the appropriate operation of the aircraft braking system and the provision of sufficient aircraft electrical power to operate the radio and appropriate external and internal lighting. }OWaMJMqh2AqFQZ-`/g25\_ R{jxHL{. No doubt these problems could be minimized if crews For instance, several runway transgressions On 26 June 2007, at Birmingham Airport UK, a BAe Jetstream 41 started an engine running pushback without using intercom between ground crew and flight crew. The aircraft ran onto the tug when the ground crew stopped the tug suddenly. If misjudged, this could result in a wingtip striking the tail of the stopped aircraft or it could compromise clearance between obstacles or other aircraft and the wingtip opposite the stopped aircraft, taxiway configuration - converging taxiways can potentially lead to reduced or compromised clearance, especially where they cross. Ignition occurs with an excessively rich mixture, leading to a rapid temperature rise that can exceed the exhaust gas temperature limit. clearance to each other. And is it really necessary to require As the signalman faces the aircraft, the nose of the aircraft is on the left. Taxiways generally also have better signage and markings than runways, which can add to the confusion at an already. reduced aircraft clearance with ground equipment or obstacles. The pushback could not be completed as the towbar could not be disconnected and confusion over a decision to return the aircraft to the gate resulted in an attempt to do so with the aircraft brakes selected which caused the aircraft nose landing gear to collapse. Limited operation may be allowed by the manufacturer. The AC now addresses aircraft being taxied by persons other than certificated pilots; adds a definition for Airport Operations Area; revises the definition for Non-Movement Area; replaces the term Ramp with Apron to harmonize with the International Civil Aviation Organization (ICAO) Annex 14 Volume 1; adds a definition for Vehicle or Pedestrian Deviation; provides guidance for towered airports on Part 139 requirements for people and equipment in the Runway Safety Area (RSA); calls for a Letter of Agreement at towered airports between the airport operator, the tower, and FAA Technical Operations; provides guidance on taxing and/or towing aircraft in the movement area by non-pilots; and incorporates numerous changes to format and content throughout the document.
