Tools

All tools are read-only. In ChatGPT the three purchase-related tools are not listed.

practice_questionsFAA practice questions

Returns 1-10 multiple-choice practice questions (3 options, like the real FAA knowledge test) from Rotate Pilot's reviewed bank for Part 107, PPL, IFR, CPL or ATP, optionally limited to one area/topic. mode=quiz (default) returns the questions without their answers; mode=study includes the answer, explanation and regulatory citations (14 CFR / AIM / ACS).

check_answerCheck a practice answer

Grades one answer to a Rotate Pilot practice question, identified by its question_id. Returns whether it is correct, the correct letter and text, the explanation and its citations (14 CFR, AIM, ACS code when available). Accepts a letter (A/B/C), a number 1-3 or the option text.

diagnoseStart an exam readiness diagnostic

Starts a free readiness diagnostic for an FAA knowledge test: returns 10-20 quiz questions (answers hidden) spread across the exam's areas — for Part 107 in proportion to the official FAA weights. Each question has a question_id; scoring the set of answers gives the result per area, how it compares with the pass mark and a suggested next step.

score_diagnosticScore an exam readiness diagnostic

Scores a set of answers to a Rotate Pilot readiness diagnostic. Returns overall and per-area results (for Part 107 also the score weighted by the official FAA area weights), the areas below the pass mark, the correct answer with explanation for each question, and a suggested next step based on the result.

exam_factsFAA knowledge test facts

Official facts about an FAA knowledge test with sources: number of questions, time limit, pass mark, answer choices, minimum age, whether an instructor endorsement is needed, retest rules after a failure, how long the result is valid, 2025 national pass rate and average score, test fee when the FAA states it, and (Part 107) the official weight of each area.

cost_of_failingWhat failing an FAA knowledge test costs

The concrete cost of failing an FAA knowledge test, with sources: fee per attempt, mandatory wait or endorsement before a retest, the 2025 national failure rate, and the expected cost of a failure. For the Part 107 test in the full profile it also states exactly what Rotate's pass guarantee covers and its conditions.

study_planDay-by-day FAA study plan

Builds a dated study plan from today to the exam date on Rotate Pilot's course material: learning blocks per area (Part 107 in proportion to the official FAA weights) with the Rotate Pilot lessons that cover each one where available, a mixed-practice block for weak areas and a final block of full timed practice tests, plus the free FAA references for that exam.

decode_metarDecode a METAR

Decodes a METAR aviation weather report into plain English: wind, visibility, weather, clouds, ceiling, temperature/dew point, altimeter and the VFR/MVFR/IFR/LIFR flight category. Pass either the raw METAR text or a 4-letter ICAO airport code to fetch the latest report from NOAA's Aviation Weather Center. For training, not for flight planning.

decode_tafDecode a TAF

Decodes a TAF terminal aerodrome forecast into plain-English periods (initial, FM, BECMG, TEMPO, PROB) with the forecast flight category of each. Pass the raw TAF text or a 4-letter ICAO code to fetch the current TAF from NOAA's Aviation Weather Center. For training, not for flight planning.

airspace_atDrone airspace at a US location

For a US ZIP code or latitude/longitude: the FAA airspace class at drone altitudes (0-400 ft AGL), the controlled airspace overhead, and the FAA UAS Facility Map (LAANC) ceiling if the point is on the grid, with a one-sentence plain-English verdict under 14 CFR Part 107. Uses FAA Class Airspace and UAS Facility Map data and USGS elevation. Checks one point only — not TFRs, NOTAMs or special-use airspace.

get_offerRotate Pilot prep options and prices

Rotate Pilot's current paid prep for an FAA exam: price, what is included, guarantee and refund terms with a link to the full terms, the free practice options, and purchase links.

compare_prep_optionsCompare FAA exam prep options

Side-by-side prices and contents of common prep options for an FAA exam, with the date the prices were checked and free alternatives. Only lists competitor prices Rotate has verified (currently Part 107); for other exams it says so instead of guessing.

start_checkoutGet the purchase link

Returns the direct purchase link for Rotate Pilot's prep for an exam (Stripe Checkout on rotatepilot.com), or the plans page when that exam has no one-click checkout. It does not charge anything: the user completes payment in their browser.

Data, limits and support

The server receives only the arguments of each tool call and does not store them. Usage statistics record the tool, the exam, the assistant and a truncated hash of the IP address. Details in the privacy policy.

Weather comes from NOAA's Aviation Weather Center and airspace from FAA and USGS public data. Both are training aids, not flight briefings. Rate limit: a few hundred calls per hour per IP.

Rotate Pilot is an independent study tool, not affiliated with or endorsed by the FAA or PSI.
