'Additional fuel' has been introduced to simplify the planning requirements for fuel contingencies.
Prior to the rule change on 8 November 2018, pilots and operators had to calculate fuel to accommodate two contingencies; engine failure and depressurisation, each with different reserve requirements.
The new rules make this calculation simpler. Now the 'additional fuel' calculation is based whichever of the contingencies requires the greater amount of fuel plus a reserve fuel of 15 minutes plus an approach and landing allowance.
Like the contingency fuel it replaces, the planning for additional fuel depends on the aircraft being a pressurised and/or multi-engined aircraft.
Explaining the rules
We have released guidance material and updated existing documents to help explain how the changes work in practice.
