Descent Profile Optimisation (DPO)


Save fuel by reducing margins in descent models

Descent Profile Optimisation (DPO) is a fuel saving initiative which updates the Flight Management System (FMS) performance database by reducing margins in descent models.

DPO is available on A320 family (Except on A319CJ and A320LIP) and A330 family and is a software only upgrade.



  • Enables a longer cruise level
  • Reduces deceleration level-off
  • Results in fuel saving benefits
