following amounts of fuel remaining:
 (a) final reserve fuel;
 (b) destination alternate fuel, if required.
 (3) The pilot in command must declare to ATS a "minimum fuel" state if:
 (a) the pilot in command is committed to land the rotorcraft at an aerodrome in accordance with this section; and
 (b) it is calculated that if there is any change to the existing air traffic control clearance issued to the rotorcraft in relation to that aerodrome, the rotorcraft will land with less than the final reserve fuel remaining.
Note 1: The declaration of "minimum fuel" informs ATS that all planned aerodrome options have been reduced to a specific aerodrome of intended landing and any change to the existing clearance may result in landing with less than final reserve fuel. This is not an emergency situation, but an indication that an emergency situation is possible should any additional delay happen.
Note 2: Pilots in command should not expect any form of priority handling because of a "minimum fuel" declaration. ATS will, however, advise the flight crew of any additional expected delays, and coordinate when transferring control of the rotorcraft to ensure other ATS units are aware of the flight's fuel state.
 (4) If the pilot in command of a rotorcraft for a flight becomes aware that the amount of useable fuel remaining on landing at the nearest aerodrome where a safe landing can be made would be less than the final reserve fuel, the pilot in command must declare a situation of "emergency fuel" by broadcasting "MAYDAY, MAYDAY, MAYDAY FUEL".
Note: The fuel emergency declaration is a distress message.

6.07  Operational variations—fuel calculations
 (1) Despite sections 6.03 and 6.04, a rotorcraft operator may use an operational variation, stated in the operator's exposition for the purpose of this section, that relates to the calculation of any of the following, if the requirements in subsections (3) and (5) are met:
 (a) taxi fuel;
 (b) trip fuel;
 (c) contingency fuel;
 (d) destination alternate fuel;
 (e) additional fuel.
 (2) To avoid doubt, an operational variation mentioned in subsection (1) cannot relate to the calculation of holding fuel or final reserve fuel.
 (3) The operator must have submitted to CASA, at least 28 days before using an operational variation:
 (a) evidence of at least one of the following, that demonstrates how the operational variation will maintain, or improve, aviation safety:
 (i) documented in-service experience;
 (ii) the results of a specific safety risk assessment conducted by the operator that meets the requirements of subsection (4); and
 (b) details of the operational variation, including procedures in relation to the use of the operational variation, proposed for inclusion in the operator's exposition.
Note: Under regulation 119.105 of CASR, CASA may
