Point I am making is a move away from simple callsigns such as *** 123 etc the move is towards horrendous mouthfuls as an atc female called it.
For example ***5UQ.
or ***5ZU.
The foreign controllers as I previously said abbreviate the mouthfuls to create other confusion with other Company Aircraft.
This procedure was previously introduced and scrapped .
One final point is that not only pilots ,atc,find this system overly complicated,but the poor people in ops dont like it either.
The original flight number and Call sign dont match therefore fitting in nicely with someones ideas on day release.
