Flying the OSHNN1 departure out from KLAX I get handed off to Departure then to Center then to another Center so quickly I barely have time to change frequency and check in with the first Center.

I had P2A configured to use the A320 aircraft type but it may need some tuning of the ATC tab of the aircraft type. I don’t know what a more realistic setting would be for the Departure range. I imagine IRL you’d stay with Departure longer while you climb via the SID.

I set the aircraft profile to departure/approach radius of 30mi and top altitude of 10000 feet and it went much better both departing KLAX and approaching KLAS. I don’t know if these setting are appropriate but now I know where the solution might be.
