Clearspar Radio Trainer

Clearspar Radio Trainer turns the part of flight training every student dreads — the radio — into something you can drill until it's automatic.

Hear a real ATC transmission, read it back (by voice or typing), and get graded instantly against the FAA standard. No instructor or flight time required.

WHAT YOU GET • 75+ graded scenarios across every phase — ground, tower, pattern, departure, en route, IFR, and emergencies • Your real home field — enter your N-number's base and practice the actual frequencies, runways, and taxiways • Live Comms: voice readbacks graded element-by-element, with the textbook answer • Ground School: phonetic alphabet, numbers, and phraseology drills — free, offline • Listening drill: copy a fast controller call through realistic radio static • Mock oral: examiner-style questions for checkride prep • Helicopter, night, and Special VFR tracks • Readiness score, weak-spot tracking, and a shareable progress card

WHY IT WORKS Every scenario is built against the FAA Aeronautical Information Manual (AIM) Chapter 4 — the same standard your CFI and examiner use. You learn the exact words, why each readback matters, and the mistakes that cause runway incursions.

FREE TO START Ground School and 5 graded radio scenarios a day are free. Go unlimited with Solo Pilot; instructors get CFI Pro to assign scenarios and track every student.

Built by pilots. Talk like you've done it a hundred times — because you will have.
