This obviously depends on how accessible, the patient is to some form of landing strip that can accommodate an EMSOS-authorized aircraft and airport take-off & landing clearance by the Patnan Air Traffic Controller. In case of Ground Ambulance transport, it can be initiated within 30 minutes of a call.
