John Boeman,
Well it is non standard R/T coming at a critical time.As I said before with the Dutch Airline,that their call for ready to turn in is often way too early.If I did as they asked they would have a non stabilised approach,intercepting above the glide.
I have had crossed transmissions with aircraft saying that they are ready for turn,and at the same time I'm calling them to turn them on base.
That takes time to sort out,and it leads to a little extra distance being covered downwind.
It seems to me that pilots say this at airports they think are quiet.A lot of the time they have got the quiet bit really wrong.It would be interesting if this phrase is heard much at Heathrow.
I don't say''evening'' or ''bye'' either.
