iranair 777 A basic reply to your questions;
Multi controllers on 119.725? seriously, how does that work?
Basically main controller plus a support controller.
Support controller is aiding with phone coordination and stack management this allows the main controller (or director) more time to plan the traffic.
Wind checks - what are they for? of course for checking wind, but why would you need wind checks at low alt. like that?
Strength and direction of the wind for Final approach controller giving him/her this information for vectoring. Maybe sometime 3000' feet wind is used for predicting the landing rate/flow requirements.
what is the different frequencies that link towards 119.725?
Sorry need to know bases only
