Do You Need a Written Test for the Helicopter CFI Add-On? Yes.

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.


What You Need to Know

  • Yes, there is a written knowledge test required for the CFI Add-On.

  • You must complete it before your check-ride.

  • The test covers teaching fundamentals, regulations, and practical knowledge you’ll need as an instructor.

  • Just like your previous ratings, preparation is key.
