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 — 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 start and end. • 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. • Each duty period's total flight time is shown right on its plate. • 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. 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 • All times in Zulu (UTC). No time-zone math. • Times only — enter times of day, not dates; the app keeps your two duty periods in sequence automatically. • 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. • Arrange legs by dragging: reorder within a duty, or move one to the other duty period. Or clear all 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.

ARRANGE LEGS • Open Arrange Legs from a duty period to see your whole plan in one list — Show, every leg, Release, the Rest, and the second duty period. • Drag a leg's handle up or down to set the order it's flown; the other legs slide aside to make room. • Drag a leg across the boundary to move it to the other duty period — it lands exactly where you drop it. • Near the top or bottom edge, the list auto-scrolls, so you can place a leg anywhere — even off-screen. ALSO • Support & Feedback moved to its own menu — and you can now attach screenshots to a report, so we can see exactly what you're seeing. • Fixed a case where moving legs between duty periods could strand a custom Show or Release time a day out, stretching a duty by a phantom ~24 hours. A show or release time that no longer fits your legs now reverts to the automatic one. RECENTLY • 2.4.2 — Total flight time per duty period, and a simpler, dateless plan. • 2.4 — Reorder your legs, and drag-to-edit to the exact minute. ### 2.4.2 — 2026-07-12 v2.4.2 — Flight time per duty, and a simpler plan. TOTAL FLIGHT TIME, PER DUTY • Each duty period now shows its total flight time at a glance — in the duty header and on the Duty Visualization — so you can see the day's block time without adding it up leg by leg. • Tap the ⓘ for what it means: it's a reference total, not a limit. The rolling 10-in-24 look-back is still the number that governs you. TIMES ONLY — NO DATES TO MANAGE • 10 in 24 now works purely from the times you enter and the order you place your legs. Your two duty periods always stay in sequence — Duty 2 simply follows Duty 1 — so a leg added out of order can't make the periods overlap or throw off the timeline. Just enter times; the app handles the rest. • Drag-to-edit polish: the fine-tune pill from your last leg now clears the moment you grab another, so it never lingers on the wrong leg. IN-APP MESSAGES • The app can now show the occasional notice when you open it — app updates, regulatory reminders, and time-critical information. • Each notice appears once and is easy to dismiss. To re-read one, open Messages from the menu — it keeps the notices you've received until they expire. • Prefer not to see them? Turn in-app messages off in Settings. Critical safety notices always show. RECENTLY • 2.4 — Reorder your legs, and drag-to-edit to the exact minute. • 2.3 — Drag to edit block-out/block-in and a duty's Show/Release on the Duty Visualization. Plus 10 in 24 on Apple Silicon Mac. ### 2.4.1 — 2026-06-26 v2.4.1 — Important notices, plus a sharper compliance check. IN-APP MESSAGES • The app can now show the occasional notice when you open it — app updates, regulatory reminders, and time-critical information. • Each notice appears once and is easy to dismiss. To re-read one, open Messages from the menu — it keeps the notices you've received until they expire. • Prefer not to see them? Turn in-app messages off in Settings. Critical safety notices always show. A SAFER 10-IN-24 CHECK • A leg accidentally dated on the wrong calendar day can quietly under-count your rolling 24-hour flight time. The duty now flags a leg that looks misdated, so the number you're trusting is the right one. RECENTLY • 2.4 — Reorder your legs, and drag-to-edit to the exact minute. • 2.3 — Drag to edit block-out/block-in and a duty's Show/Release on the Duty Visualization. Plus 10 in 24 on Apple Silicon Mac. ### 2.4 — 2026-06-23 v2.4 NEW: Reorder your legs — and drag-to-edit to the exact minute. REORDER LEGS • Put your legs in the order you fly them: on a duty period, tap Reorder and drag the legs into place. • And they now keep the order you enter them — an after-midnight leg (say a 0100Z leg added after a 2237Z leg) stays in sequence and rolls to the next day, instead of jumping to the top of the list. DRAG TO EDIT — NOW PRECISE • Fine control as you drag — slide your finger away from the chip edge to slow the adjustment down and settle on the exact minute. Stay near the edge for fast, coarse changes. • Or set it after the fact — a −1 / +1 pill appears when you finish a drag, so a tap or two lands the precise minute. • Stretch without running out of room — pull the first duty's Show earlier or the last duty's Release later and the timeline scrolls to follow, so long duty periods and overnight rests set in one motion. Plus: Reorder, Move, and Clear are now one-tap buttons on each duty period. RECENTLY • 2.3 — Drag to edit: retime block-out/block-in and a duty's Show/Release right on the Duty Visualization, with a live time-and-limit readout. Plus 10 in 24 on Apple Silicon Mac, so Cockpit Sync can link iPhone, iPad, and Mac. • 2.2 — Duty Visualization: your whole two-duty plan drawn to scale, with elapsed-time rulers, look-back brackets, tap-to-explain pills, an Extended Rest projection, and a dockable iPad layout. ### 2.3 — 2026-06-16 v2.3 NEW: Drag to edit — change your times right on the timeline. • Drag a leg's edge in the Duty Visualization to retime its block-out or block-in. The Show, Turn, and Release around it flex to absorb the change, down to the minimums you set — so the rest of the day stays honest. • Drag the Show or Release edge to set a duty's start and end the same way. • A live readout follows your finger: the new time, the segment's total length, and a heads-up the moment you bump into a minimum. • Works in portrait and in landscape, where slanted grips ride right on the chip edges. • New Minimum Show and Minimum Release limits in Settings, alongside your quick-turn minimum. ALSO NEW • 10 in 24 now runs on Apple Silicon Mac — so Cockpit Sync can link iPhone, iPad, and Mac over a direct, serverless connection. Open the timeline with the bar-chart icon in the planner's top bar, then press and hold a grip on any edge to grab it. RECENTLY • 2.2 — Duty Visualization: your whole two-duty plan drawn to scale — Show, legs, turns, Release, and the Rest between duties — with elapsed-time rulers, look-back brackets, tap-to-explain pills, an Extended Rest projection, and an iPad layout you can dock where you like. • 2.1.1 — Original one-time purchasers: tap Restore Purchases to unlock lifetime access.
