The Fixated Student
You are a CFII on the third instrument lesson with a private pilot who has 48 total hours, 6.4 hours of simulated instrument time, and a checkride booked in three weeks. Today's plan is localizer tracking with constant-rate turns. Twice now, when you assign a left turn through 090, he stares at the CDI, the bank rolls past 30 degrees, he gains 300 feet, and he recovers only after you call the bank. He says, "I can't watch three instruments at once." His logbook since the first lesson shows nothing but straight-and-level work. The aircraft owner, who has the checkride date blocked on the schedule, tells you to "keep him on pace."
1. What is actually breaking down here, and why has repeating the same maneuver twice failed to fix it?
Read the worked answer
What is breaking down: not the maneuver, and not a lack of effort. The student is fixating on a single instrument (the CDI) and flying the airplane in discrete "snapshots" instead of a continuous cross-check. When he looks down at the CDI, pitch and bank inputs stop; the airplane diverges; he then overcorrects. That is task saturation produced by a scan he was never taught.
Why repetition isn't working:
- Law of primacy. What is learned first is learned strongest. He has now practiced fixation dozens of times in straight-and-level work; you are asking him to un-learn a habit under a heavier workload.
- Law of exercise. Repetition of a flawed behavior strengthens the flaw, not the fix.
- Learning plateau. Performance has flattened because the underlying sub-skill (scan) is missing, not because he needs more reps of the same task.
- Building-block principle. Turns, tracking, and trimming have never been separated, so he cannot tell which input caused which indication.
Calling the bank for him also teaches him to wait for you - that is dependency, another primacy problem you are creating.
2. What do you do in the next fifteen minutes of this flight?
Read the worked answer
Stop the maneuver and rebuild it in layers, in the airplane, with immediate correction:
- Attitude indicator first. Cover nothing yet - have him roll into a standard-rate turn on the attitude indicator only, with power set and the airplane trimmed, and hold altitude to plus/minus 100 feet. Say nothing for 30 seconds, then debrief.
- Add one instrument. Attitude plus airspeed, then attitude plus altimeter, then attitude plus turn coordinator. Short intervals (30-45 seconds), immediate, specific correction - "you looked at the CDI for four seconds; say 'attitude' out loud before every cross-check."
- Verbalize the scan. Have him call the sequence aloud: attitude, airspeed, attitude, altimeter, attitude, CDI. The verbal crutch fades in one or two lessons.
- Reduce the workload, don't add to it. Cancel the constant-rate-turn exercise and the localizer work for today. Two knots of crab and a stable heading beat a perfect turn flown badly.
- Chair-fly it. Ten minutes on the ground tracing the scan pattern beats ten more minutes in the air reinforcing fixation.
The owner never flies the lesson; you do. Do not let the schedule dictate the teaching sequence.
3. Do you keep the three-week checkride date? What is your obligation as the recommending instructor?
Read the worked answer
No - and it is not a close call.
- He is not eligible yet. The instrument rating requires a substantial block of instrument time, a defined number of hours with an authorized instructor, and cross-country and night experience; at 6.4 hours of hood time he is not near those minimums. The endorsement question is moot.
- The endorsement is a certification, not a formality. The practical-test endorsement attests that you have given the required training and determined, recently, that the applicant meets the standards. You cannot certify what you have not seen, and you have just watched him lose control of the airplane in a turn while fixated.
- Outside pressure is legally irrelevant. The owner's schedule and the student's deposit do not transfer the responsibility. If you sign and he fails - or worse - the endorsement is yours.
What to do instead: tell both of them today, in plain language, what the deficiency is, what the plan is to fix it, and roughly how many hours you expect. Put it in the student's training record. Offer a different checkride date now while the schedule still has room, and re-brief the owner that the date was never guaranteed.
