The objective; of this course is to familiarize learners with the many tasks that take place in pre-flight, at takeoff, during cruse and landing phase of the flight. We provide students with the foundation and advance knowledge and skills on the processes that need to be followed by in-flight services staff & ground staff in order to service a parked aircraft. These services include all the functions required to help move passengers, cargo and baggage on board. In addition, airport ground services personnel may perform the final walk around of the aircraft to check that all doors are closed and all is well. They work closely with the pilot of the aircraft to start the engines safely, communicating with the headset link or with hand signals. They help “push back” the aircraft from the parking position before the engines start running fully, a task referred to as marshalling the aircraft. Moreover, the course content has been enriched with numerous illustrations in order to a support learning and knowledge retention. Hence, it is recommended to carefully study the content and refer to the relevant illustrations that support it.
