As a society, we know that we have to reduce CO2-emissions if we are to avoid the severe consequences of climate change. Stakeholders in the air transport industry have been working on many fronts to reduce fuel burn and emissions for each flight. One important factor in this effort is to enable continuous descent operations and to avoid unnecessary fuel burn.

This course is aimed at flight crews and pilots who would like to become more familiar with continuous descent operations (and to a lesser extent continuous climb operations), why CDO matters and how ATC instructions affects a flight crew’s ability to carry out CDOs.

This course also provides the theoretical basis for understanding CDO and acts as an enabler for flight crews to facilitate more CDOs, and CDOs from higher levels, to the extent possible in their operational environment.
By the end of this course, the student should have the knowledge required to:
  • Explain what CDO and CCO are
  • List the benefits of CCO/CDO
  • Explain the factors that affect CCO/CDO
  • Describe the impact of airspace/procedures design on CCO/CDO
  • Discuss the advantages and disadvantages of open and closed STARs 
  • Discuss how ATC instructions affect the type of flying technique the flight crew may use
You need to plan 4 hours to complete this course.
Flight crews and pilots or anyone who would like to have a basic understanding of CDO.
This course is free of charge.
