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. The warning threshold is adjustable to your operator's culture.

EARLIEST LEGAL BLOCK-OUT, CALCULATED LIVE

Under each planned leg, see the earliest time you could push back without busting a rule — factoring in 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, down to your minimums. Drag the Show or Release edge to set the duty's start and end. A live time-and-limit readout tracks every drag.
• Elapsed-time rulers on each duty period and the rest gap read directly against the 14-hour duty limit and the 10-hour rest minimum — each duty's closing value colored by your compliance status.
• Look-back brackets show which legs eat into a rolling 10-in-24 window, and the window the rest calculation measures.
• Tap any ⓘ for a plain-language explanation — what the number measures, the applicable 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 — drag-to-edit works there too, and the view keeps your place.
• On iPad, dock the timeline as a popup, side pane, or bottom pane; it updates live and remembers your arrangement.
• And a rotating line of crew humor on the turns and overnights.

FLY WITH A CREW? COCKPIT SYNC

Captain and FO each running 10 in 24 can link devices — even across iPhone, iPad, and Apple Silicon Mac — over a direct peer-to-peer connection. No internet, no router, no 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

• Universal — runs on iPhone, iPad, and Apple Silicon Mac.
• All times in Zulu (UTC). No time-zone math.
• 24-hour clock everywhere.
• Block-out / block-in entry that auto-rolls overnight.
• Mark a leg complete to lock in actual block times — the running calculation switches to your real numbers.
• Per-duty show / release time overrides for each duty period.
• Single-pilot or two-pilot crew configuration.
• Quick actions: reorder legs, move Duty 2 into Duty 1 when your planning day rolls over, or clear everything to start fresh.

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.
