CAVOK is a private digital pilot logbook for student pilots, private pilots, commercial pilots, and flight instructors operating under FAA Part 61. Log detailed flights, see the experience your records support, and review what needs attention before you fly. No CAVOK account, no ads, and no social feed. LOG FLIGHTS WITHOUT THE CLUTTER • Record aircraft, routes, block times, total time, PIC, SIC, solo, dual, night, cross-country, and actual or simulated instrument time • Track takeoffs, landings, holds, instrument approaches, simulator time, flight reviews, IPCs, checkrides, crew, instructors, and remarks • Search and filter your flight history • Duplicate a previous entry when you fly it again • Display time as decimal hours or hours and minutes REVIEW FAA CURRENCY EVIDENCE • See day and night passenger recency by category and class • Review IFR recency, flight review, and supported medical certificate dates • Understand current, expiring soon, and incomplete evidence with requirement details • Get optional on-device reminders 30, 7, and 1 day before supported items expire CAVOK uses conservative record-based calculations. If your logbook does not contain the evidence a rule requires, CAVOK shows what is missing instead of assuming the requirement is met. TURN FLIGHT TIME INTO USEFUL INSIGHTS • Review totals for all time, year to date, 12 or 6 months, and 90 or 30 days • Explore hours by month, aircraft type, category, and class • Prepare with an experience report organized using FAA Form 8710-1 terminology • See totals for each aircraft KEEP PORTABLE, VERIFIABLE RECORDS • Import flights from CSV with automatic header matching • Export a classic paginated logbook PDF with page and running totals • Export spreadsheet-friendly CSV files • Create and restore complete backups • Capture instructor endorsements and signatures • Preserve corrections and tamper-evident audit history • Restore recently deleted flights before permanent removal PRIVATE BY DESIGN Your pilot records stay on your device and, when iCloud is available, in your private iCloud database. CAVOK has no pilot account system or pilot-record server, and the developer cannot read your logbook. You decide when to export or share a file. TRY CAVOK FREE Use the complete feature set with up to 20 flights, 5 aircraft, and 5 endorsements. Upgrade to CAVOK Pro for unlimited records with monthly, yearly, and lifetime purchase options. Subscriptions renew automatically unless canceled in your Apple Account settings. IMPORTANT CAVOK supports FAA Part 61 record review. It is not an official FAA record and does not determine whether you may act as pilot in command. Currency results are decision support. You remain responsible for checking current regulations, certificates, ratings, endorsements, medical status, operating rules, and all facts relevant to a flight.
