Note: This question is a recent development of question 909751.

A good way to get these questions right, is to use:

• NIP = Nature of problem - Intention - Position

Looking at the correct answer:

• Mayday, Mayday, Mayday - Always MAYDAY x3
• Barcelona Control - Station being called
• Jetsun 1154 - Your call sign
• depressurisation problem - NATURE OF PROBLEM
• descending FL100 - INTENTION
• overhead BCN VOR, leaving FL350, heading 050. - POSITION
