Airworthy: Instrument Rating

Master every IRA area—regs, weather, clearances, navigation, approaches—with 330 cited questions, smart SRS flashcards, and a 60-question full practice exam.

Airworthy: Instrument Rating is the fastest, most rigorous study companion for the FAA Instrument Rating – Airplane knowledge test (IRA).

• 330 questions across every Area of Operation in FAA-S-ACS-8C – regulations (14 CFR 61 / 91), instruments and systems, weather theory and products, ATC clearances, holding procedures, VOR / ILS / GPS / RNAV navigation, departure and en-route, instrument approaches, and emergency operations.

• Every question is cited – sourceId, locator, and SHA-256 hash matching the FAA Instrument Flying Handbook (FAA-H-8083-15B), Instrument Procedures Handbook (FAA-H-8083-16B), Aviation Weather Handbook (FAA-H-8083-28B), Airman Certification Standards (FAA-S-ACS-8C), and current 14 CFR Parts 61 + 91 via eCFR.

• Smart SRS flashcards (90 cards) surface what you almost forgot, right before you do.

• 60-question full practice exam drawn proportionally from every topic – 70% to pass, just like the real IRA.

• Streaks, levels, badges. Five-minute sessions that compound.
