What this lesson is for: closing everything the mock found, confirming you are ready, and either writing your practical test recommendation or saying honestly what still stands in the way.

Back with your own Supervising Instructor. The mock was somebody else's job on purpose. This decision is theirs.

It is the shortest lesson in the program and it carries the largest decision in it. Half an hour, after forty-one lessons, in which a person puts their name to a statement that you are ready to be assessed as a flight instructor.

The one hard gate in this program

Every applicable ACS area has to be at PROFICIENT before your recommendation is written.

You will have noticed by now that nothing else in this program works this way. Falling short of a lesson's completion standard has never stopped you starting the next lesson. That is Decision 9, it is deliberate, and policy/REMEDIATION-VISIBILITY.md explains why: blocking progress over a skill that comes back with practice stalls the whole program and makes the bill arrive as one unexplained lump at the end.

This is the exception, and it is at the end rather than throughout. You are never held back from learning. You are held back from being tested, and only until the gap closes.

Three things are confirmed today, and all three are hard conditions:

  1. Every applicable ACS area at PROFICIENT, area by area, not as an average.
  2. Every knowledge test deficiency code closed, with the instructor who closed it and the date.
  3. Every row on your deficiency list closed, consciously accepted, or deferred with a date.

"Consciously accepted" is a real outcome and not a loophole. A row can be closed because you met it, or accepted as a known weakness that still sits above the standard, recorded as such with a reason. What it cannot do is quietly disappear.

What your recommendation actually says

61.39(a)(6) sets the wording, and it certifies three things about you:

  1. That you have received and logged training within the 2 calendar months preceding the month of application, in preparation for the practical test.
  2. That you are prepared for the required practical test.
  3. That you have demonstrated satisfactory knowledge of the subject areas you were deficient in on the knowledge test.

Read it before it is signed. The second one is a judgment your instructor is making in their own name, in a federal training record, on a certificate they hold. You will be writing the equivalent for your own Students within a year, and this is the last chance to see one written about you.

Point 1 carries a clock that expires quietly. Two calendar months, counted back from the month you apply. If your examiner slot moves, this is the item that can lapse without anything feeling like a deadline. Note the date today.

If the recommendation is withheld

That is this program working, not failing.

The alternative to a withheld recommendation is a notice of disapproval, which costs you money, time, and confidence. If a candidate reaches a practical test not ready, the recommendation was wrong, and that is stated plainly in policy/DISAPPROVAL-AND-DISCONTINUANCE.md.

If it is withheld you will be told exactly what closes it, and by when. Not a feeling, and not "a bit more work". A named gap, a named piece of work, and a date. Anything less than that is not useful to you and you should ask for it.

Before you arrive

Read:

  • Your own deficiency list from lessons 40 and 41, in full. Come with a view on every row.
  • Your copy of program/COVERAGE-MATRIX.md, the Proficiency column, area by area.
  • Your knowledge test deficiency closure log.
  • 61.39(a)(6), from the live regulation. This is the endorsement that will be written in your logbook today and you should know what it says before somebody signs it about you.

Bring:

  • Your logbook. The endorsement is written in it today.
  • Evidence for any deficiency row you believe is closed. Specific evidence, in the form your deficiency closure log uses: what you did, to whom, on what date.

Also bring one answer, thought about in advance: which ACS area would you rate yourself lowest in, and why. You will be asked before you hear our view, and an honest answer is worth more here than a confident one.

What we will cover

  1. Your deficiency list from lessons 40 and 41, row by row.
  2. The outcome of each row: closed, consciously accepted, or deferred with a date.
  3. The coverage matrix, area by area.
  4. Your knowledge test deficiency log, confirmed closed.
  5. The recommendation decision.
  6. The 61.39(a)(6) endorsement, written into your logbook.
  7. The 2 calendar month window, and what happens if your test slips.
  8. Booking the day-before confirmation pass on your document checklist.

What you will do

  1. Work through the deficiency list row by row.
  2. Produce evidence for any row you believe is closed.
  3. Say which ACS area you would rate yourself lowest in, before hearing our view.
  4. Hear the recommendation decision and the reasons for it.
  5. Read the endorsement written in your logbook, and say what it certifies about you.
  6. Note the date the 2 calendar month window expires against your booked test.

How you will be assessed

Standards 1 to 4 are conditions on the program, not on you. Standards 5 to 8 are yours.

  1. Every row on the deficiency list from lessons 40 and 41 is marked closed, consciously accepted, or deferred with a date, each naming the human who decided and the date they decided. No row is left unresolved.
  2. Every applicable ACS area in program/COVERAGE-MATRIX.md is at PROFICIENT, or the recommendation is withheld and the reason is recorded.
  3. Every knowledge test deficiency code is confirmed closed, with the closing instructor and date recorded.
  4. The recommendation is written or withheld as an explicit decision, stated out loud to you, and recorded with the name of the person who made it and the date.
  5. You state which ACS area you would rate yourself lowest in, and why, before hearing the instructor's view.
  6. You read the 61.39(a)(6) endorsement written in your logbook and state what it certifies, including that it certifies you are prepared for the practical test.
  7. You state the date the 2 calendar month training recency window expires for your booked test, and what happens if the test slips past it.
  8. You name at least one thing from the deficiency list you will keep working on after you hold the certificate.

Standard 8 is not a formality. Your deficiency list is written so that it can be read by somebody who was not there, after you hold the certificate, and post-certificate mentorship picks it up. A candidate who leaves this lesson thinking the list is finished has misunderstood what it is for. Nobody finishes their first year of instructing with nothing on it.

What usually goes wrong

  • Treating this as a formality because you have reached lesson 42. Reaching it is not evidence. The decision is made here, not ratified here.
  • Expecting a deficiency row to quietly go away. Every row gets one of three outcomes and vanishing is not one of them.
  • Wanting an area accepted at NEEDS WORK because the test is already booked. A booking is not a reason. The test moves.
  • Offering "we discussed it" as closure on a knowledge test code. Your examiner has your test report and will ask. Bring what you actually did.
  • Not knowing what your own endorsement certifies. You will be writing these for Students within a year.
  • Forgetting the 2 calendar month window when the test slips. It expires quietly, and nothing about it feels like an expiry date.
  • Hearing a withheld recommendation as a verdict on you. It is a plan with a date attached, and it is a great deal cheaper than the alternative.
  • Believing the deficiency list ends at certification. It does not, and it is not meant to.

When I will take the airplane

Not applicable. This is a ground lesson and we do not fly it.

The last intervention threshold in this program is in the lesson 41 study guide.

Video

Not applicable. Video Slots hold Clips of a Student flying a maneuver. This lesson teaches no maneuver and shows no flying.

This lesson is complete and deliverable whether or not any Video Slots exist.
