Learn to teach in the clouds! Take Your Flight Instructor career to the next level and become an instrument instructor (CFII). With the recent FAA regulation requiring at least 10 hours of instrument flight training for all commercial pilot applicants, many flight schools have found it necessary to hire a higher percentage of CFII instructors. Going the extra mile and becoming a CFII will make you a much more qualified and employable instructor, allowing you to teach on all VFR and IFR courses.
