Descent Profile Optimisation - DPO

Pioneering sustainable aerospace for in-service aircraft

What you get

Fuel savings

DPO reduces fuel consumption, resulting in proportional C02 and NOx reductions.

Relaxing Idle Margin

The level of Idle considered to compute the descent profile is reduced, resulting in a less conservative slope.

Update engine performance model

Using a more accurate engine model allows to compute a more realistic descent profile. The differences between managed and open descent are highly reduced.

Optimise your descent profile

DPO updates the Performance Database of the aircraft Flight Management System (FMS) to enable consistently more efficient descents by allowing the aircraft to remain in the cruise phase longer and removing the ‘level-off’ stage at the bottom of the descent, which reduces carbon emissions. In addition, the Continuous Descent Approach (CDA) works in tandem with DPO to reduce noise. 

The DPO function enables aircraft to use an optimum engine model to compute the profile of the descent, requesting less fuel when the engine is using idle thrust. In addition, it maximises the time spent at efficient cruise level by setting the top of descent later in the profile.
