such circumstances.
       (3) The pilot in command must not operate a Part 131 aircraft in tethered flight:
(a) on the movement area or the runway of a relevant aerodrome; or
(b) within 2 NM of such an aerodrome;
        unless the operator holds, for the purposes of this subsection:
(c) a CASA approval under regulation 131.035; or
(d) the written permission or approval of the operator of the relevant aerodrome.
       (4) For subsection (3), relevant aerodrome means a non-controlled aerodrome listed in the AIP-ERSA.
Note   A non-controlled aerodrome includes an aerodrome that at times has ATC but where the ATC service is not operating.
       (5) A person must not operate a Part 131 aircraft in tethered flight in such a manner as to create an obstruction to an aircraft taking off from, or approaching for landing at, the following areas of any aerodrome:
(a) a marked rotorcraft landing area;
(b) a rotorcraft landing area identified as such in the authorised aeronautical information;
(c) a runway.

CHAPTER 21 FUEL AND BALLAST REQUIREMENTS

21.01 Purpose
        For subregulation 131.385 (1), this Chapter prescribes requirements relating to fuel and ballast for a Part 131 aircraft, whether or not it is conducting a balloon transport operation.
Note   Fuel, in the form of liquid petroleum gas, is used in hot air balloons, hot air airships and mixed balloons to control altitude by heating the air inside the envelope. Ballast (as defined in subsection 1.06 (5)) is used in a gas balloon to control altitude by initiating ascent and controlling descent through the progressive release of the ballast. A gas balloon flight must terminate when the ballast is exhausted.

21.02 Definitions for this Chapter
        In this Chapter:
final reserve fuel means the calculated amount of usable fuel, expressed as a period of time, required to be remaining in the fuel tanks on completion of the final landing of a flight before ground handling.
night operations fuel for a hot air balloon or hot air airship means the amount of fuel required to enable an aircraft, that is conducting a flight under the VFR at night, to remain airborne until conducting a landing by day.
trip fuel means the amount of fuel required to enable a hot air balloon or hot air airship to fly from any point along a route until landing at a suitable landing area.
unforeseen factors means factors that could have an influence on an aircraft's fuel consumption to a suitable landing area, including the following:
(a) the aircraft's deviation from the expected fuel consumption data for the aircraft;
(b) extended deviations from planned routings or altitudes.
