an emergency situation is possible should any additional delay occur.
Note 2: A pilot in command should not expect any form of priority handling because of a "minimum fuel" declaration. Air Traffic Services will, however, advise the flight crew of any additional expected delays, and coordinate when transferring control of the aeroplane to ensure other air traffic control units are aware of the aeroplane's fuel state.
        (4) If the pilot in command of an aeroplane for a flight becomes aware that the amount of usable fuel remaining on landing at the nearest aerodrome where a safe landing can be made would be less than the final reserve fuel, then the pilot in command must declare a situation of "emergency fuel" by broadcasting "MAYDAY, MAYDAY, MAYDAY FUEL".
Note: The emergency fuel declaration is a distress message.

7.09  Operational variations—fuel calculations
 (1) Despite sections 7.04 and 7.05, an operator may use an operational variation, specified 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) a copy of the operator's procedures, proposed for inclusion in the operator's exposition, in relation to using the operational variation.
Note: Under regulation 119.105 of CASR, CASA may direct the operator to remove or revise the operational variation, if CASA were to find there was insufficient evidence that it would maintain or improve aviation safety.
 (4) For the purposes of subparagraph (3)(a)(ii), the specific safety risk assessment must include at least the following:
 (a) flight fuel calculations;
 (b) the capabilities of the operator, including:
 (i) a data-driven method that includes a fuel consumption monitoring program; and
 (ii) the use of sophisticated techniques for determining the suitability of alternate aerodromes; and
 (iii) specific risk mitigating measures.
 (5) For the purposes of subsection (1), the operator's exposition must include procedures in relation to the use of the operational variation.
