airspace_at
Drone 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.

check_answer
Check 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.

compare_prep_options
Compare 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.

cost_of_failing
What 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.

decode_metar
Decode 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_taf
Decode 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.

diagnose
Start 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.

exam_facts
FAA 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.

practice_questions
FAA 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).

score_diagnostic
Score an exam readiness diagnostic
Scores a set of answers to a Rotate Pilot readiness diagnostic.
