majuro - thanks for explaining your TLA - I am used to another TLA for that
(Say an aircraft was accidently overloaded everyday by the same amount...... I see that this would, by way of aerodynamic and induced drag increase the PDA).
- as Canuck says - irrelevant. You would then have a 'PDA' for every flight, regardless of CI, so your performance monitoring programme (PMP
) would pick this up and show that particular a/c as a 'rogue' performer and the fuel burns should be adjusted (eventually)
