PilotPeak

PRECISION. PERFORMANCE. PROTECTION. PilotPeak is the advanced Fatigue Risk Management System (FRMS) engineered for the modern aviation professional. Bridging the gap between regulatory limitations and human physiology, PilotPeak empowers pilots with data-driven situational awareness. Designed for high-reliability environments, our platform integrates proprietary biomathematical models with Apple HealthKit data to provide a comprehensive analysis of your fitness for duty. THE PILOTPEAK ADVANTAGE: Enterprise-Grade Fatigue Analytics Move beyond simple flight time limitations. Our "Bio-Metric Engine" processes sleep quality, Heart Rate Variability (HRV), and circadian rhythms to visualize your Alertness Index. Anticipate performance dips before they occur. Secure & Anonymised Data Architecture. PilotPeak employs enterprise-grade data handling protocols. While the system processes biometric and operational data to generate analytics, all processing is performed using de-identified methodologies. Your fatigue metrics are utilized strictly for analytical performance and are never linked to your personal identity or user profile on our servers. Intelligent Roster Digitization (OCR) Streamline your administration. Our advanced Optical Character Recognition (OCR) module instantly converts physical and digital rosters into actionable data—automatically logging Flight Duty Periods (FDP), Block Times, and Rest intervals. Microsleep Risk Assessment Utilizing probabilistic modeling, the system identifies patterns correlated with lowered alertness states. This predictive layer supports your decision-making for strategic caffeine intake or controlled rest planning. GLOBAL COMPLIANCE SUPPORT: • Digital Logbook: Generates reports compatible with FAA, EASA, and ICAO formatting standards (PDF/CSV). • Currency & Type Rating: Automated tracking for validity and recency requirements. • Faith & Flight: Integrated high-precision prayer times and Qibla direction for global operations. • Offline Sovereignty: Full analytical capabilities at 40,000 ft without internet dependency. CRITICAL OPERATIONAL DISCLAIMERS NON-MEDICAL DEVICE PilotPeak is a data visualization and tracking utility. It is NOT a medical device and is NOT intended for the diagnosis, cure, mitigation, treatment, or prevention of any disease or medical condition. The "Alertness Index" and "Microsleep Risk" are probabilistic estimates for educational purposes only. REGULATORY STATUS PilotPeak is an independent support tool and is NOT certified by the FAA, EASA, ICAO, or any aviation authority as an official Flight Time Limitation (FTL) calculator. It does not replace your operator’s approved Operations Manual (OM/A) or official rostering system. PILOT IN COMMAND RESPONSIBILITY The user assumes full responsibility for all "Fitness to Fly" decisions. Compliance with applicable aviation regulations (e.g., FAR Part 117, EASA ORO.FTL) remains the sole obligation of the pilot. Do not rely exclusively on this application for safety-critical decisions. LIMITATION OF LIABILITY By using this platform, you acknowledge that PilotPeak and its developers are not liable for any direct or indirect consequences arising from the use of this software, including but not limited to operational incidents, regulatory fines, or scheduling errors.

ZuluRest helps airline pilots manage fatigue and stay legal. Built for every US flight crew — Part 121 passenger and cargo, Part 135, fractional and corporate — it combines sleep tracking, duty tracking and fatigue risk assessment in one app that knows your rule set. YOUR RULES, NOT SOMEONE ELSE'S • Part 117: Tables A, B and C, split duty, reserve, cumulative limits, consecutive nights and home rest after long trips • Part 121 Subpart Q domestic cargo, Subpart R flag and Subpart S supplemental • Part 135 scheduled and on-demand, Part 91K fractional, Part 91 • Pick your airline and base once; ZuluRest sets your rule set, home clock and base list • FedEx pilots see contractual limits beside the FAA figures • Every limit cites its CFR section FATIGUE RISK SCORING A real-time score from your actual sleep, time awake, circadian rhythm, duty length and flight segments. See the factors behind the number, and debrief after a duty to check the prediction against how you felt. DUTY & FDP TRACKING • Quick-start a duty in two taps or log the full day with segments • Live FDP countdown on the Dashboard, the Lock Screen and in a widget • Rolling and calendar cumulative limits for your rule set • Augmented crews: 3- and 4-pilot limits and rest facility class • Duty history with route and report–release times; a flight log in each airport's local time TRIPS & LAYOVERS • Import a pairing from a PDF, screenshot or pasted text; duty days, show times and layovers are built for you • A fatigue forecast for every day of the trip under best, realistic and poor sleep • Layover rest strategy: body clock on arrival, a sleep window in local time, a nap plan and reminders • Weekly rest tracking (30-in-168, 1-in-7, quarterly) that starts and ends with your schedule RESERVE CALCULATOR "What if I get called?" — long call, short call and airport standby, with the short-call reserve cap, release time, segment and flight-time limits, WOCL overlap and a rest check. BOTTLE TO THROTTLE A timer and BAC estimate against the FAA 8-hour / 0.04% rule, your airline's policy and the rules where your next duty reports (EU and UK 0.02%, Canada 12 hours). See the last drink that keeps your next report legal. SLEEP • Log sleep in seconds with presets, in the time zone you woke up in, or sync with Apple Health • Sleep trends across trips, with quality and location • Sleep debt and its effect on your score FLIGHT LOGGING • Automatic flight detection by airport proximity, in the background • Landing alerts from your uploaded schedule • Mark each leg as your landing or the other pilot's, and export the log to CSV • 500+ airports; location stays on your device LEGALITY TOOLS • Rest before duty, weekly rest, cumulative limits, consecutive nights • Landing currency: your own landings in the last 90 days, with reminders before it lapses • Medical certificate and recurrent training tracking with reminders WIDGETS & LIVE ACTIVITIES Fatigue score, FDP remaining and sleep totals on your Home Screen; a live duty countdown on the Lock Screen. BUILT FOR PILOTS Designed by an active airline pilot who understands the challenge of managing fatigue in aviation. Whether you fly cargo or passengers, domestic turns or international routes, ZuluRest helps you make informed decisions about your fitness to fly. PRIVACY FIRST Your data stays on your device.
