Bultaco,
If you have done 6 approaches within last 6 months - you are current.
If not but its less <6 months then you are do 6 approaches on your own duirng normal course of your flying.
If you are 6-12 months since last 6 then you need to do 6 with a safety pilot.
If you are 12+ months then you need an IPC with an FAA Instructor.
Julian.
