I've established that once you clear a plane to land, it doesn't matter how close another plane gets to it.
It also seems that a plane landing behind another plane has no parameter for separation. Is this everyone else's experience?
Finally, I can't seem to pin down the parameter for a plane taking off in front of a landing jet. It seems like if I have a plane already waiting on a runway and the landing plane comes within 1000ft of the field, there is no violation. However, if I have a plane at 1200 feet above the field and I clear a plane that is not on the runway to takeoff, and the landing plane descends within 1000ft of the field a few seconds later, I get a violation.
Can anyone articulate the parameters for separation of a landing plane behind a plane taking off? Does a plane that has already lined up and waited have a different parameter?
Trying to squeeze planes in as close as possible ;)
