I am practicing to become an Air Traffic Controller and I have a confusion about when exactly to clear for landing/the option versus simple sequencing or saying “continue inbound” without yet giving clearance.
For example, When do you say:
“Delta 219 Heavy, Number 2, cleared for the option”
“Delta 219 Heavy, Number 2, traffic to follow on is final”
The public ATC manual does not specify the difference, or maybe I missed it. Just to clear any confusion, I am NOT asking about the difference between cleared for landing and cleared for the option as many members have on the forum. I am asking about when to clear. Because I also know that the runway doesn’t have to actually be vacant at the moment of clearing for the aircraft to be cleared.
Edit: The only part in the manual that talks about this is in the image bellow, but it doesn’t specify at what stage exactly do you clear (aka conditions that need to be met before clearing) and what are the conditions behind “If Required”:
