Thanks for the explanation.
The original post did not mention any specific airport..and only 2 min separation...so I was trying to point out that there is a myriad of standards, not just 2 mins.
As pointed out, at LHR, DP ac do an immediate turn. This is a scenario gets you to a 45 second departure timing.
Every operation has rules for its specific combination of operating procedures, that have waded through the regulatory quagmire to get to what works for them.
I am curious, back to the original question, how would an operator know, unless a regular, to expect wheels up in 45 seconds behind a heavy?
