Typically after you earn your helicopter certified flight instructor (CFI) rating, you can then complete the certified flight instructor instrument rating. There are no additional flight experience requirements in the helicopter beyond preparing with a qualified Instructor Pilot (CFII) for the oral and practical flight test (Check Ride) with the FAA examiner.
• Minimum 18 years old to take the practical flight test
• Hold a commercial pilot helicopter certificate with an instrument rating with a minimum of 150 hours of flight time
• Must read, write, understand, and speak english
• Hold a current FAA medical certificate
• Pass FAA written fundamentals of instruction and helicopter flight instructor instrument written knowledge tests (FOI exam from your CFI counts so you don’t have to do it twice)
• Pass an FAA oral and practical flight test
You will be expected to meet the standards in the FAA Practical Test Standard (PTS) for the helicopter Flight Instructor Instrument rating. You will be expected to demonstrate all the Commercial and Instrument PTS flight maneuvers from the (Instructor’s) seat in the aircraft as you explain those maneuvers as you would to a student pilot.
You will also be required to pass a rigorous oral examination with an FAA Inspector on the subject matters covered in the FAA’s Certified Flight Instructor Instrument practical test standard (PTS) publication.
You are also required to pass two written FAA knowledge tests. One covers the fundamentals of instruction and covers how people learn and how they should be taught. The other is a test on general aviation information that any Certified Flight Instructor should know. (FOI exam from your CFI counts so you don’t have to do it twice)
