As
lackov said, the CAAPs are not legally binding. However, if you want your Operations Manual approved with a fuel policy that is not compliant with the 'expert' CAAP recommendations, be prepared to surrender sufficient operational documentation and
working evidence to CASA to prove that your company fuel policy is adequate.
In the light of operational experience (particularly with regular freight or RPT) you will soon determine
exactly how much fuel is required for a particular operation.
