PBN Airspace Design with focus on TMA, CDO’s, CCO’s (classroom)



About the course

5-day (40 hours) classroom course

Well-planned airspace designs need to take into account traffic sector loads, navigation capability of aircraft, surrounding terrain, man-made obstacles and any special use airspace. Airspace designers must also consider the optimum vertical profiles of aircraft that take the form of continuously climbing (CCO) or descending (CDO) operations. However, achieving optimal vertical profiles for both departing and arriving aircraft is challenging. Equally, Airspace Planners as well as Procedure Designers need to select the correct terminal and approach Navigation Specifications (Nav Specs), and be knowledgeable of area navigation, i.e. ARINC 424 path-terminators, and corresponding navigation sensors on board aircraft to enable use of the new procedures by majority of the aircraft operating within the TMA. Maximizing airspace efficiency and overall airport capacity should be the main strategic objectives of any TMA redesign projects.

This course is available at IATA Training Centers and Regional Training Partner locations, and on-demand as in-house training.
