Flight Time Calculations & Crew Rest Management The essential two-in-one utility for flight crews and aviation professionals is here, combining a powerful, flexible Aviation Time Calculator with an intelligent Crew Rest Splitter. Designed by pilots for pilots, this app minimizes manual workload and eliminates mental math errors during critical phases of flight. 1) FLIGHT TIME CALCULATOR A robust tool engineered to handle the unique demands of aviation mathematics. Unlike standard calculators, this module processes time in hours and minutes natively—perfect for logbook totals and FTL tracking. Intelligent Input Recognition: Quick Format (HHMM): Simply type '1030' for 10 hours 30 minutes. Standard Format (H:MM): Use the colon separator for traditional entries. Minutes Only: Type '45' for 45 minutes. Running Total: Keep an eye on your accumulated time right on the screen. Perfect for summing up block times for an entire month or year. Calculation History: Hit the 'H' button to see your last 10 operations. Never lose track of your logbook entries again. Direct Time Arithmetic: Add or subtract flight times directly without the need for decimal conversions. 2) CREW REST CALCULATOR Create fair, accurate, and operational-ready rest schedules in seconds. This module eliminates awkward splits and ensures equitable rest distribution for the entire crew. Smart Rounding (NEW): Introducing an intelligent rounding toggle! Align rest end times to the nearest 5-minute interval. Our fair-share algorithm automatically redistributes remainder minutes across all periods to ensure the most equitable distribution possible. Multi-Crew Support: Instantly generate rest periods for 2, 3, or 4 pilot operations (Augmented and Heavy crews). Gap Management: Specify optional handover gaps (5, 10, or 15 minutes) to account for seat changes, briefings, and cockpit procedures. Conflict-Free Results: Get a perfectly balanced rest plan in seconds—clear, readable, and ready to share with your team. WHY PILOTS CHOOSE THIS APP: Fully Responsive: Switches cleanly between portrait and landscape for easy use on any phone or tablet. High-Contrast Design: Focused, clean UI that cuts out visual noise, making it easy to read in various cockpit lighting conditions. Pilot-Centric Logic: Engineered for the speed and precision required in real-world flight operations. Streamline your cockpit operations today with accurate, reliable, and pilot-focused tools.
