Über diesen Test
Practice for the FAA Commercial Pilot helicopter (CRH) knowledge test with original questions written from the current text of 14 CFR Parts 61 and 91 on eCFR (current as of 2026-10-26), the FAA Helicopter Flying Handbook (FAA-H-8083-21B) and the Pilot’s Handbook of Aeronautical Knowledge (FAA-H-8083-25C). Every correct answer is backed by a passage of the source and checked by two independent verifiers.
- Study: every question with a short explanation.
- Topic drills: regulations and privileges, helicopter aerodynamics, helicopter systems and performance, maneuvers and emergencies, weather, airspace, navigation and decision-making.
- Mock test: 100 questions, 70 correct (70%) to pass, as the FAA Airman Knowledge Testing Matrix (revised 9/25/26) states for test CRH.
The questions are written in our own words; this is not the FAA’s question bank. Chart, figure and computer questions that need images are not included.
