What's the minimum distance you can taxi an aircraft past another aircraft that is refuelling? The CAOs dont seem to specify, but it stands to reason there has to be a safety limitation.
CAO 20.9 4.1.1 During fuelling operations, the aircraft and ground fuelling equipment shall be so located that no fuel tank filling points or vent outlets lie:
(a) within 5 metres (17 ft) of any sealed building; and
(b) within 6 metres (20 ft) of other stationary aircraft; and
(c) within 15 metres (50 ft) of any exposed public area; and
(d) within 15 metres (50 ft) of any unsealed building in the case of aircraft with a maximum take-off weight in excess of 5 700 kg (12 566 lb) and
(e) within 9 metres (30 ft) of any unsealed building in the case of aircraft with a maximum take-off weight not exceeding 5 700 kg (12 566 lb).
What about a moving aircraft??
4.4.3 A person shall not, and the pilot in command and the operator shall take reasonable steps to ensure that a person does not, during fuelling operations:
(b) except in the case of aircraft, operate an internal combustion engine or any electrical switch, battery, generator, motor or other electrical apparatus within 15 metres (50 ft) of the aircraft’s fuel tank filling points or vent outlets, and ground fuelling equipment unless the engine, switch, generator, motor or apparatus complies with the provisions of Appendix I to this Order and has been inspected.
Why not in the case of aircraft?? I presume this means the aircraft's own engine, but what about another aircraft taxiing past you??
