Teaching a technical subject: the shape, and principles of flight

The candidate teaches a technical subject to a Simulated Student rather than reciting it, and learns the shape every remaining phase 2 lesson uses. The subject is principles of flight, chosen because the candidate already knows it cold as a pilot, which isolates the teaching problem from the knowledge problem.

This is the phase 2 tracer bullet. It is the first time the technical subject shape meets real content.

Element 2 is the one that transfers. The candidate knows all of elements 3 to 8 already. What they have never done is decide what a person who does not know it needs first, and what can wait.

Element 6 is where most candidates over-teach. Four turning tendencies, each with a mechanism, is more than a primary student can hold at once. Watch whether the candidate prioritizes or dumps.

Instructor: FAA-S-ACS-25 at AI.II.D. FAA-H-8083-25C and its October 2025 addendum. A model airplane or anything with a wing. standards/TECHNICAL-SUBJECT-LESSON-SHAPE.md.

Candidate: preparation deliverable, whiteboard access.

Capture: as below.

Taught Ground Lesson: yes Meeting title convention: CFI Ground Lesson - L08 Principles of Flight - <YYYY-MM-DD> Participants: each on their own device, headset, Workspace account Candidate reads their own Session Transcript before the instructor's review Coverage maps to: AI.II.D Fallback if capture fails: instructor attests from contemporaneous notes; the lesson is not lost and is not re-taught for the sake of a recording

1. Set up phase 2 in element 1. Be explicit that the candidate already knows this material and that the lesson is not about whether they know it.
2. Teach elements 2 to 8. Model the organizing decisions out loud as you go: say why you are introducing the four forces before stability rather than after.
3. Assign the element for element 9 at the start of the lesson, not in advance.
4. Simulated Student role. A primary student around 10 hours. Ask "why" twice on the same point. Ask one question that requires the candidate to admit a simplification they made.
5. Do not let a whiteboard diagram substitute for an explanation.
6. Critique against standards/CRITIQUE-STANDARD.md.

1. Arrive with the deliverable.
2. Teach an assigned element for about ten minutes to the Simulated Student.
3. Handle "why" twice on the same point without either repeating themselves or retreating to maths.
4. Self-critique first.

Identical wording in the study guide.

1. The candidate teaches an assigned element of principles of flight to the Simulated Student for about ten minutes, without notes in front of them.
2. The candidate answers "why" twice on the same point, going one level deeper each time rather than restating.
3. The candidate names one simplification they made and says what it costs and when it would need correcting.
4. The candidate directs the Simulated Student to a live publication at least once, rather than asserting a fact from memory.
5. The candidate prioritizes within element 6, teaching the turning tendency that matters most at the student's stage rather than all four equally.
6. The candidate delivers a self-critique before hearing the instructor's.

Not applicable. Ground lesson.

Read:

• FAA-S-ACS-25, Area of Operation II, Task D. The task itself.
• FAA-H-8083-25C, Pilot's Handbook of Aeronautical Knowledge, the aerodynamics chapters, plus the October 2025 addendum.
• standards/TECHNICAL-SUBJECT-LESSON-SHAPE.md. This is how every phase 2 lesson works.

Deliverable: A one-page teaching outline for load factor in turns, aimed at a student with about 10 hours. Say what you would teach first, what you would leave out entirely, and one question you would ask to find out whether it landed.

Available and used: the 2026-07-29 power-off stalls lesson. Use it for element 2. That lesson is a technical subject taught to a Simulated Student by a candidate who could already fly the maneuver, which is exactly the situation here. Ask the candidate what the teacher had to decide before speaking, and what they would have ordered differently.

Needed and not yet available: a real North Aero primary ground lesson recording, so the candidate can watch a technical subject taught to an actual Student rather than a role play. Owner: Erick.

None. This lesson teaches no maneuver.

This lesson is complete and deliverable whether or not its Video Slots are filled. It has none.

Grade the organizing, not the aerodynamics. The candidate's knowledge of principles of flight is not in question and treating it as though it were wastes the lesson.

This is the first Taught Ground Lesson of the program. Set the capture habit here: separate devices, headsets, structured title. If attribution has not yet been tested, say so to the candidate rather than letting them assume the Coverage output is trustworthy.
