This video forms part of the coursework for students enrolled in one of the courses at Aviation English Academy. As part of their coursework, students are asked to listen to this recording and to validate the importance of proper read-back when confirming instructions.
This recording provides an almost perfect example of potential miscommunications which occur on international flights and the importance of read back. This is an Air China aircraft communicating with JFK Ground. As you can tell, the potential for disaster is there.
