Beacon Separation
As an old and bold procedural controller my technique is: Get twr to line up the departure. As soon as the beacon traffic calls beacon outbound wait 30 seconds, then release the departure climbing unrestricted straight ahead. Get it on frequency early, as soon as it is 1000 above the beacon traffic turn it on track.
This works provided the beacon traffic has not called commencing base/ procedure turn.
If in doubt keep the beacon traffic going out bound until you have the level swop provided the sector altitude allows!
Satisfies all of the necessary separation standards!
Ah, the days of no radar! 😁
