Rotate Pilot

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.

check_answer

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.

study_plan

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_metar

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.

decode_taf

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.

airspace_at

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.

exam_facts

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).

practice_questions

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.

score_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.

diagnose

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.
