@alisonjane,

I suspect that this is a non-native English speaker who is trying to get their commercial pilot's license. The language of air traffic controllers and pilots is English.
You're not helping this person, nor are you helping this person's future passengers. Pilots have to become much more than proficient in reading to pass an exam. They have to become fluent in listening and speaking English in order to land their plane and its passengers with all the pieces in the same order that they were when they left the ground.
