R44 Checklist

Features
Read full description

BUILT BY PILOTS, FOR PILOTS. The complete companion for Robinson R44, R44 II, and R44 Cadet operations Every checklist item, every emergency procedure, every limitation in this app traces directly back to the R44 POH. No shortcuts, no generic helicopter content — just accurate, type-specific reference built for the aircraft you actually fly. FULL CHECKLISTS with notes, ALL THREE VARIANTS — FREE Switch instantly between R44, R44 II, and R44 Cadet. Each variant has its own complete set of normal and emergency procedures, because the differences between them matter: different engines, different power ratings, different limitations, different emergency sequences. Get the wrong checklist and you get the wrong answer — so this app never guesses. Select your aircraft once and every checklist, warning light response, and emergency procedure updates automatically. Normal procedures cover the full flight from preflight through shutdown. Emergency procedures cover engine failures, drive system failures, fire, electrical issues, hydraulic loss, water landings, and more — organized exactly the way you'd need them in the moment, not buried in dense paragraphs. INSTRUCTOR MODE — YOUR BUILT-IN EXAMINER This is what sets R44Checklist apart. Instructor Mode is a full knowledge-check engine built from hundreds of POH-sourced questions across limitations, systems, normal procedures, and emergency scenarios — all specific to whichever R44 variant you're flying. Emergency questions are presented as real-world scenarios, not textbook definitions — you'll be asked to sequence the correct response to a developing situation, the way an examiner or instructor actually tests you. Get something wrong, and it comes back around later in the session so you actually learn it, not just guess through to the end. Score 80 or above and you pass. Below that, you'll see exactly where the gaps are and can try again immediately. FLIGHT PLANNING BUILT FOR HELICOPTER OPERATIONS Set a destination, drop custom waypoints anywhere on the map with a simple tap and hold, and build multi-leg routes for jobs that don't fit a standard airport-to-airport flight plan — pinnacle work, confined areas, agricultural strips, private helipads. Toggle into FLY mode during flight and get live ground speed and estimated time enroute calculated directly from GPS, or stay in PARK mode for planning-stage estimates based on your default cruise speed. WEATHER WHEN AND WHERE YOU NEED IT Live METAR and TAF for any airport, plus current conditions at your destination — wind, visibility, temperature — pulled in automatically the moment you set a destination. FLIGHT LOG AND DEBRIEF Every flight is automatically logged with engine start and stop times, duration, route, and conditions. Generate a clean, professional flight debrief as a PDF in seconds — ready to file, share, or keep for your own records. Export your entire flight log to CSV whenever you need it. FLY WITH A CREW CrewSync lets two devices stay in sync in real time during dual-pilot or instructional flights — checklist items checked on one device reflect instantly on the other, so nobody's working from a different page. APPLE WATCH COMPANION Keep essential flight data on your wrist without breaking your scan — engine status, current phase, and key indicators, synced automatically from your iPhone. SIRI SHORTCUTS Jump straight to any checklist phase with a voice command, hands-free when you need them most. WHY R44Checklist? Most checklist apps are generic. Most performance and reference apps only cover one variant, or charge separately for each. R44Checklist covers all three R44 variants in a single app, built from the actual POH for each one, with a genuine knowledge-testing engine included — not bolted on as an afterthought.
