For those flying bigger aircraft your I/R used to be automatically renewed when you did your base check on the sim. Now you do a type specific LPC rather than an instrument rating, and can't legally fly a Seneca in airways. If you don't renew your I/R within a certain time (7 years?) would you have to go back to CAAFU (or whatever its called nowadays) or would it just be a renewal with an examiner to reactivate it?
