Flight Instructor · Phase 3 · Lesson 25 · Study guide
FAA references verified 2026-08-13 | v1.0, 2026-08-13
What this lesson is for: learning the four-part cycle that every remaining flight lesson in this program runs to. You will teach the four fundamentals of flight, fly them while talking, watch somebody else fly them badly, and say something useful about it.
The maneuver is easy on purpose. You have flown the four fundamentals to commercial tolerance since lesson 23. Everything hard about today is the teaching.
This lesson is recorded. See below.

FAA-S-ACS-25, Area of Operation IV, task AI.IV.A, in full. This is the task your brief is graded against.FAA-S-ACS-25, Area of Operation VIII, all four tasks.standards/MANEUVER-LESSON-SHAPE.md, the four-part cycle and addition 2.FAA-H-8083-9B chapter 5, demonstration and performance.Deliverable: Write the preflight ground lesson you will teach on the four fundamentals, to the template in standards/LESSON-PLAN-TEMPLATE.md, covering all seven items of the brief. Bring it on paper. This is one of your seventeen P3 plans, covering a fundamental of flight. Bring the tolerances written down, from the ACS, not from memory.
Every flight lesson from here to the checkride runs these four, in this order.
Part 3 is the new one. You have flown a lot and been taught a lot. You have probably never had to watch somebody else fly badly, in an airplane you are responsible for, and produce one useful sentence at the moment it would still help.
AI.IV.A tests, and why your brief is graded rather than being a warm-up.Out loud, three ways, both directions, every single time:
"You have the flight controls." "I have the flight controls." "You have the flight controls."
At some point today the airplane will not be offered to you. You will have to take it. That is deliberate, it happens in every phase 3 lesson, and it is the part of US-5.4 that cannot be learned by reading about it.
Two ways this goes wrong, both common:
Falling short does not block lesson 26. There is no proficiency gate. It triggers the visibility rule in policy/REMEDIATION-VISIBILITY.md. This lesson is the baseline the rest of phase 3 is read against, so if today is a struggle you will hear that plainly and it is worth acting on early.
2,300 ft".Hard floor: all air work is terminated by 1,500 ft AGL. That is North Aero policy and it is above the regulatory minimum on purpose.
Positive exchange of controls, both directions, every time.
Three slots, all currently empty: VS-25-1 Exemplar on AI.VIII.B, VS-25-2 and VS-25-3 Errors on AI.VIII.B and AI.VIII.C.
This lesson is complete and deliverable whether or not its Video Slots are filled.
This flight is recorded, and it is one of four in phase 3 that are. It is the baseline: lesson 38's recording gets compared against it, which is the point of doing it now rather than later.
You watch it and critique your own teaching before your instructor reviews it. The written assessment is the record. The footage is deleted after 30 days.
The camera changes nothing about when I take the airplane. The threshold above is the threshold.
