2.402 Continuous descent operations (CDO)
DESCRIPTION:
Percentage of continuous descent vs total descent distance flown.
STRATEGIC OBJECTIVE:
Air Navigation Capacity and Efficiency
INDICATOR TYPE:
Activity-related (Predictive or Leading)
RATIONALE:
This indicator allows measuring and optimization of vertical flight efficiency during the descent phase which in turn reduces cost and emissions.
LIMITATIONS:
Aircrafts must be equipped with automatic dependent surveillance broadcast (ADS-B) transmitter.
CALCULATION METHOD/FORMULA:
CDO = (sum of all distances flown in CDO in km / total descent distance flown in km) x 100
