Crew Duty Time

Crew Duty Time is a crew duty, rest, and flight-time reference calculator built for flight crew who need a fast short-term planning tool before and during duty.
Enter a route, review planned sector times, compare company-style duty limits, track rolling flight time, and keep key duty milestones visible on iPhone and Apple Watch.

Key features:
• Route-based duty planning with STD, STA, planned flight time, ACT OUT, and ACT IN fields
• Configurable company-style settings for report time, taxi time, maximum flight time, maximum flight duty time, LBO, rest, and related limits
• Live Activity and local notifications for REPORT, STD, DLY, and LBO stages before ACT OUT is entered
• Apple Watch companion view for quick leg review and time entry
• In-flight rest planner for multi-crew and double-crew duty planning
• Rolling 24-hour flight-time reference
• Cabin limits shown as reference information
• Local profile import/export for reusable company settings
• Offline-oriented workflow with local calculations and no account requirement

Crew Duty Time is designed as a planning and reference tool. It is not an official regulatory system, company-approved dispatch system, or legal compliance guarantee. Flight crew must confirm final duty, rest, and flight-time legality against the applicable company manuals, authority regulations, operational control requirements, and current operational conditions.
