From Instrument Pilot to Instrument Instructor

The biggest mistake new CFII candidates make is treating the checkride as "fly instrument approaches, but better." Your flying ability is assumed. The Instrument Flight Instructor ACS (FAA-S-ACS-8) evaluates whether you can teach instrument flying and manage risk while a less-capable pilot is at the controls.

• Your scan is divided. You must monitor the student, the instruments, and traffic/terrain simultaneously. You will fly an approach while your eyes are mostly on the student.
• You teach from a degraded position. From the right seat the attitude indicator parallax, throttle quadrant reach, and brake access are all different. Practice every demonstration from that seat.
• You must talk and fly at once. Effective instruction is continuous narration of what you are doing and why, without losing aircraft control.

1. Pilot in command / safety. You are almost always the PIC and the legal safety authority. You decide when to take the controls.
2. Instructor. You diagnose, demonstrate, and correct.
3. Risk manager. You keep the flight inside acceptable margins despite a developing pilot's errors.

The Aviation Instructor's Handbook (FAA-H-8083-9) describes four levels: Rote, Understanding, Application, Correlation. An instrument student who can recite the steps of a missed approach (rote) is not safe. Your goal is correlation — the student associates a low approach light, a deteriorating scan, and fuel state into a decision. Design every lesson to push toward correlation, not memorization.

When you demonstrate a maneuver for instructional purposes, you fly it to commercial/instructor ACS standards — tighter than the instrument-rating applicant. A bank within 100 feet of an assigned altitude is acceptable for a private student; your demonstration of a holding pattern should be visibly precise because it is the model.
