I have a question:
If I have 2 sequenced planes on left downwind, and I need to build space between then, I will call “I call your base” to the both of them.
When time is right, I will start with the number 2 aircraft (behind nr.1) and call “Turn base”. (as showed in “The perfect ATC test” video at 12:00 minutes)
Then I will tell him he is now nr.1 (he is now being changed/squenced from nr.2 to nr.1).
Then I go over and tell the “old” nr.1 that he is now nr.2 TRAFFIC TO FOLLW IS ON LEFT BASE.
?! Will he (the new nr.2) turn he’s base as him self? -or will he still be waiting for my command “turn base” before he will turn?
