10 in 24

Stay legal. Plan smarter.

10 in 24 is a flight-time and rest planning tool for FAA Part 135 charter pilots, built around 14 CFR § 135.267. Sketch out your next two consecutive duty periods and see — in real time — where you stand against every limit that matters.

WHAT IT CHECKS

• 10 in 24 — § 135.267(b). Rolling 24-hour flight time, evaluated at every leg's block-in. 10 hours for two-pilot crews, 8 hours for single-pilot.
• Rest Look-Back — § 135.267(d). Confirms 10 consecutive hours of rest in the 24 hours before Duty 2 completes.
• Duty Length — § 135.267(c). Each duty period, from show to release, capped at 14 hours.

SEE YOUR STANDING AT A GLANCE

Every leg gets a live status indicator — green for slack, yellow approaching the line, orange in the last five minutes, red when you've gone over.

EARLIEST LEGAL BLOCK-OUT, CALCULATED LIVE

Under each planned leg, see the earliest time you could push back without busting a rule — accounting for prior rest, the 14-hour duty ceiling, the previous leg, and the rolling 10-in-24 window.

SEE THE WHOLE DAY

The Duty Visualization draws your entire two-duty plan as a timeline to scale: Show, every leg, every turn, Release, and the rest between duties — long legs look long, quick turns look quick.

• Drag a leg's edge to retime its block-out or block-in; the adjacent show, turn, and release flex to absorb it. Drag the Show or Release edge to set the duty's bounds.
• Elapsed-time rulers on each duty and the rest gap read against the 14-hour duty limit and 10-hour rest minimum, colored by your status.
• Each duty period's total flight time is shown right on its plate.
• Tap any ⓘ for a plain-language explanation of each number, its limit, and where you stand.
• If the plan carries an exceedance, an Extended Rest chip shows the mandated rest after your final release, and why.
• Rotate to landscape for a horizontal timeline. On iPad, dock it as a popup, side pane, or bottom pane — it updates live and remembers your arrangement.

YOUR DUTY DAYS — SAVED & SYNCED

• Saved Plans — keep a library of duty days, not just one. Create, open, rename, duplicate, or delete plans; new plans are named by date and fully editable.
• iCloud sync — your plans follow you across iPhone, iPad, and Mac on the same Apple ID, automatically. No accounts, no servers.
• Save or print a report — export any plan as a clean PDF or plain text to share, print, or file.

FLY WITH A CREW? COCKPIT SYNC

Captain and FO each running 10 in 24 can link devices — across iPhone, iPad, and Apple Silicon Mac — over a direct peer-to-peer connection. No internet or servers. Push your plan across with the other side's OK, then every edit mirrors live to the other seat. Off by default; opt in per flight with a matching pairing code.

BUILT FOR THE COCKPIT

• All times in Zulu (UTC), 24-hour clock — no time-zone math.
• Times only — enter times of day, not dates; the app keeps your two duty periods in sequence automatically.
• Block-out / block-in entry that auto-rolls overnight.
• Mark a leg complete to lock in actual block times.
• Per-duty show / release time overrides.
• Single-pilot or two-pilot crew configuration.
• Arrange legs by dragging: reorder within a duty, or move one to the other duty period.

IMPORTANT

10 in 24 is a planning aid only. A projected exceedance means the schedule isn't assignable as built — under Part 135 a duty day may not be planned to exceed a regulatory limit, and extended rest exists for exceedances that arise in actual operations. Final responsibility for compliance with § 135.267 rests with the certificate holder and the pilot in command. Always verify against your operator's official records.
