Weather information and the taught briefing

The completion standard is a delivered briefing on live weather, on the actual day of the lesson, for a flight that could actually be flown. Not a description of how to brief. A briefing.

That is US-4.5's requirement and it is what makes this skill transfer directly to a student briefing on the candidate's first day as an instructor.

Element 7 is the teaching content. A briefing that recites every product in order is a data dump. A student needs the shape of the day first, then the specific things that will affect their flight, then a decision.

This lesson reuses North Aero's existing weather briefing material rather than duplicating it, per US-4.5. See the note below.

Instructor: live weather, on the day. An actual proposed flight for the candidate to brief. FAA-S-ACS-25 at AI.III.C. North Aero's existing weather briefing material.

Candidate: preparation deliverable, device with weather access.

Taught Ground Lesson: yes Meeting title convention: CFI Ground Lesson - L21 Weather and the Taught Briefing - <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.III.C 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 the proposed flight before the lesson, and make it realistic: a local dual lesson, or a student solo cross-country. The candidate briefs that flight, on today's weather.
2. Teach elements 1 to 7.
3. Simulated Student role, element 8. A primary student who wants to know one thing: are we flying. Interrupt with that question if the briefing turns into a data dump.
4. Do not let the candidate brief a hypothetical day. Live weather, today, or the standard is not met.
5. Critique against standards/CRITIQUE-STANDARD.md.

1. Arrive with the deliverable.
2. Deliver a briefing on today's live weather, for the proposed flight, to the Simulated Student.
3. Reach a go or no-go and state the reasoning.
4. Say how they would have the student reach the decision themselves next time.
5. Self-critique first.

Identical wording in the study guide.

1. The candidate delivers a briefing on live weather, for a stated flight, on the day of the lesson. This is the completion standard and nothing substitutes for it.
2. The briefing leads with the shape of the day, then the specifics affecting this flight, rather than reciting products in order.
3. The candidate reaches a go or no-go and states the reasoning, including what would change the answer.
4. The candidate names the specific hazard most relevant to today, rather than listing all six.
5. The candidate says how they would have the student reach that decision rather than delivering it to them, on a later flight.
6. The candidate distinguishes official from unofficial sources when asked.
7. The candidate delivers a self-critique before hearing the instructor's.

Not applicable. Ground lesson.

Verbatim in the study guide.

Read:

• FAA-S-ACS-25, Area of Operation III, Task C.
• FAA-H-8083-25C, the weather chapters, plus the October 2025 addendum.
• North Aero's existing weather briefing material. Ask your instructor for it.

Deliverable: On the morning of the lesson, brief yourself on today's actual weather for the flight you will be given, and bring a one page written briefing in the structure you intend to deliver. You will deliver it live, so it will already be slightly out of date. That is realistic and it is part of the exercise.

Second deliverable. Write the ground lesson you would teach on weather information and the taught briefing, to the template in standards/LESSON-PLAN-TEMPLATE.md, in your own words. This is one of your seventeen P3 plans, covering the weather cluster. Bring it on paper.

The briefing above is the performance. The plan is how you teach somebody to build one.

Used: today's live weather. This lesson's worked example is by definition real, every time it runs, which makes it the strongest lesson in phase 2 on that measure.

Open item, and it moved on 2026-08-14. US-4.5 requires this lesson to reuse the existing North Aero weather briefing material in this folder rather than duplicating it. That material has been located. It is reviewed and it is not yet adopted. This lesson still points at it rather than reproducing it, which is the correct behavior under US-4.2 either way, so nothing about delivering this lesson changes today.

What was found, and it is substantial. The North Aero Weather Briefing Guide, May 2026, sourced paragraph by paragraph to the Aviation Weather Handbook and to the FAA's own preflight briefing advisory circular. It carries an eleven-step briefing sequence, product reference pages for METAR, TAF, surface analysis, prog charts, AIRMETs, SIGMETs, PIREPs, winds aloft, radar and satellite and the graphical forecast tool, each with red flags and cross-checks, plus a cross-reference matrix, an electronic flight bag appendix and a personal minimums worksheet. A copy is in materials/reused/.

Why it is not adopted yet, and this one is not a defect. The guide teaches a pilot to brief. This lesson has to teach a candidate to teach briefing, and the guide carries no common student misconceptions, no teaching sequence and no assessment. It is the right reference and it is only half of what US-4.5 needs. There is a weather misconception map in the same Drive root that may be the missing half and has not been reviewed. Adoption also requires source register entries for the handbooks and advisory circulars the guide cites, none of which this program has yet. Owner: Erick. See materials/MATERIALS-REVIEW.md.

None. This lesson teaches no maneuver.

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

The live briefing is the whole assessment. If the weather is beautiful and settled, the briefing is short and the decision is easy, and the standard is still met. Do not manufacture complexity; brief the day you have.

If the day is genuinely marginal, this becomes the best lesson in phase 2. Take it.
