Pilot 2 atc classic airliners

Does anyone know the best way to set up p2atc for classic airliner ifr? Like I want to fly the dc6 vor to vor and only use sids/stars/approaches that are possible by this equipment type but it keeps assigning me stuff that is not possible in this aircraft

Go into the config and there are options there to specify which types of approaches, etc, or to force user assignment.

Read the manual to ensure you understand what the settings mean / do.
