Program Professional Framework
A-CDM in Airport and Ground Operations
Program Overview
Airport Collaborative Decision Making (A-CDM) turns the turnaround into a shared, time-stamped process between the airport operator, airlines, ground handlers and air traffic control. The programme explains the A-CDM concept elements and milestone approach, the key target and calculated times such as TOBT, TSAT and TTOT, variable taxi time and pre-departure sequencing, and how adverse conditions are managed collaboratively. It focuses on what ground operations teams must do to provide accurate, timely data, how A-CDM links to the Airport Operations Centre (AOC/APOC), and how performance is measured, drawing on EUROCONTROL guidance and implementations at major Gulf hubs.

Training Methodology
Applied Project & Assessment
Applied Project
Participants analyse a sample day of turnaround milestone data from a Gulf hub scenario, calculate TOBT accuracy and taxi-time indicators, identify the main delay drivers, and propose procedure and data quality improvements for the ground handling team.
Assessment
Short diagnostic at the start, practical tasks linked to each learning outcome, and evaluation of the applied project against published criteria.
