Pre-Solo Written Test Requirements: A Flight School Guide to 14 CFR 61.87(b)

A student arrives at the desk on a Friday morning ready for a first solo. The instructor has the syllabus signed, the airplane is fueled, the wind is down the runway, and the weather brief is clean. The dispatcher pulls the file and asks where the corrected pre-solo written test is. Nobody has it. The instructor remembers handing out something a few weeks back but cannot find the graded paper, the student record has no scan of it, and the logbook endorsement that says the test was passed was never written. The flight does not happen. The student goes home, the instructor reconstructs the test that afternoon, and a planned first solo turns into another week of waiting.

That scenario is preventable, and the prevention is mostly process. The pre-solo aeronautical knowledge test is one of the few items 14 CFR Part 61 spells out in concrete terms, and one of the most commonly mishandled at the recordkeeping step.

What 14 CFR 61.87(b) Actually Requires

14 CFR 61.87(b) is short and specific. Before a student pilot conducts a solo flight, the student must have passed an aeronautical knowledge test administered by an authorized instructor. The test has to cover the applicable parts of 14 CFR 61 and 91, the airspace rules and procedures for the airport where the solo will be conducted, and the flight characteristics and operational limitations of the specific make and model. The same instructor who administers the test reviews every incorrect answer with the student before endorsing the logbook to certify a satisfactory result.

The regulation does not specify a passing score, the number of questions, the format, or the time limit. Those are the school's call. What is not optional is the coverage, the in-person review of wrong answers, and the logbook endorsement that records the test was taken and passed. Skip any one of those and the solo authorization rests on nothing the FAA recognizes.

Building the Test Content

A working pre-solo test runs forty to seventy-five questions. Fewer than forty and the coverage 61.87(b) requires is hard to hit. More than a hundred and the test starts to test patience rather than knowledge.

The three coverage buckets shape the question pool. The regulation portion pulls from the parts of 61 and 91 a student pilot will actually rely on: student pilot privileges and limitations, basic flight rules, right-of-way, minimum safe altitudes, and the visibility and cloud clearance minimums that govern VFR. Schools running a primary fleet at a non-towered field need the non-towered pattern conventions covered here, since the student will be using them on every solo lap.

The airspace section covers the airport-specific environment. The home field's pattern altitude and direction, the CTAF or tower frequency, displaced thresholds, noise abatement, ridge or obstacle warnings, and the surrounding controlled airspace the student might wander into. A generic Class B question buys little. A question about the lateral limits of the Class D one valley over, which the student will see on every climbout, buys a lot.

The make and model section is the one schools shortchange most often. V-speeds, fuel capacity and unusable fuel, electrical and fuel selector positions specific to this airframe, and the published normal and emergency procedures should all be testable. A student who can recite the regulation but cannot say what Vx is in the airplane they are about to solo is not ready. The underlying material lives in the FAA's Pilot's Handbook of Aeronautical Knowledge and the specific aircraft's POH, and the test should make a student demonstrate they have used both.

Administering and Grading

The test is administered by an authorized instructor, which under 61.87(b) means a CFI. The most common setup is a written test taken at the school in a quiet room, closed book, with the student's preflight planning materials available only when the question explicitly references a chart or the POH.

Grading and the wrong-answer review are inseparable in the regulation. The instructor scores the test, then sits with the student and walks every missed question back to the regulation, chart, or POH passage that produces the correct answer. That conversation is what the FAA expects as evidence the student understands the material, not the percent correct on the cover sheet. A student who scored 95 and never reviewed the three wrong answers got less out of the test than a student who scored 78 and reworked the missed items with the instructor.

Pick a passing threshold and apply it across the bench. Eighty percent is a common number. What matters less than the exact figure is that every instructor uses the same one, with the same wrong-answer review discipline. The same consistency that drives aircraft checkout procedures belongs here. Two CFIs running the pre-solo test three different ways produces unequal graduates and an uneven safety floor.

Recording the Test and the Endorsement

The pre-solo knowledge test is one of three records that have to be in the file before a student can fly solo. The corrected test itself, the logbook endorsement that the test was passed, and the solo endorsement under 61.87(n) for the specific make and model. The first one is the one schools lose most often, because it lives outside the logbook on a paper sheet that gets filed somewhere a dispatcher cannot reach on a Saturday morning.

A clean record set has the corrected test scanned or stored digitally against the student's file, the date it was administered, the score, the instructor who graded it, and a pointer to the logbook endorsement that followed. The dispatcher releasing the airplane on a solo flight should be able to confirm in seconds that all three exist for this student and this make and model. A platform like HangarOS that already carries the student record, the syllabus, and the booking can hold the pre-solo test alongside them rather than as a separate paper trail.

Where Schools Get Caught

The recurring failure modes are predictable. The test exists but lives on a clipboard the chief instructor took home. The grade was reviewed verbally but the corrections were never written on the paper. The endorsement was made in the logbook but the test itself was discarded after the student soloed, leaving no record an FAA inspector can audit. None of these violate the airmen certification standards on test day. All of them surface during a Part 141 audit or after an incident, when the inspector asks for the pre-solo file and the school produces a verbal account instead of a document.

A student who solos on a properly administered pre-solo test with the records intact is also a student who is genuinely better prepared, which is the underlying point. Tracking the test is not paperwork for its own sake. It is the difference between an authorization that can be defended and one that cannot. The same operational discipline that puts an open squawk in front of the dispatcher belongs here. The pre-solo file is a dispatch input, and it should live where dispatch can see it.
