I have always wondered how you should pronounce "XIDIL".
Normally flying airways you will have a copy of your approved flight plan.
You will know the expected intersection points enroute.
In the UK where they speak clear BBC English you should not have a problem understanding what the controllers say.
BUT!!!!!!!!!!!! cross into France and its a nightmare undestanding the intersections you are cleared to.on many occasions you have to ask for a spelling as the pronunciations in no way are anything like what you think they should be.
I would not worry too much in the UK pure luxury
"XIDIL". is pronounced X IDIL
