When pilots work toward their Certified Flight Instructor (CFI) Add-On, there’s one requirement that often comes as a surprise: the written test.
It’s not unusual for pilots to assume that once they’ve already completed written tests for their previous ratings, the CFI Add-On will be just about teaching and flying. But the FAA requires a separate written knowledge test specifically for the CFI Add-On.
Why This Surprises Pilots
We’ve seen it time and again — pilots show up ready for their check-ride, only to discover they’re missing the written test endorsement. That mistake can delay your check-ride, cost you more money, and stretch out your training.
It’s a small detail, but an important one.
