I’d like to see them like the de-ice pads, where it shows where the service road connections must be. For stands, that connection could be the same place as now (on the terminal side only) to not require any or much change to on-stand pathing. But it would allow a single service road to service remote stands on both sides, or even one way service roads, or single lane service roads.
Ideally I’d like to see the ability to connect either on terminal side or Apron side - maybe with connector nodes shown and the connection is satisfied if one is connected. However, I suspect they may create a lot of work on the code side of things.
