I have a student that wants to get an instrument rating, kinda nice since im getting burned out just doing primary instruction. The new student has his private pilot certificate airplane single engine land. He also has a commercial helicopter and instrument helicopter. So for this he does not need to take another instrument knowledge test? And just needs to have 50 hours of PIC cross country and at least 10 hours of that in fixed wing airplane?

Just want to make sure. Never thought I would get a situation like this. Kinda seems like a question an examiner would ask on a check ride.
