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 air traffic controllers who would like an insider view of the flight crew perspective on continuous descent operations (and to a lesser extent continuous climb operations), why CDO matters and how ATC instructions affects a flight crews ability to carry out CDOs.

This course also provides the theoretical basis for understanding CDO and acts as an enabler for ATCOs to facilitate more CDOs, and CDOs from higher levels, to the extent possible in their operational environment.
By the end of the course, participants should be able 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 can affect the energy management of an aircraft
  • Explain how ATC can facilitate CDO
