On standby. Halfway through your duty. Close to your limits. Duty+ gives you the numbers that matter, instantly — plus your rolling 7/14/28-day totals, always to hand.
The one number that matters, right now: how much duty have you got left today?
Not a logbook. Not a spreadsheet. Duty+ answers that question the moment you need it — mid-duty, on standby, wondering if discretion's coming into play.
ON THE DAY
Live countdown to your latest on-chocks time
Called from standby? Duty+ rolls straight into your duty with the reduction already applied
Split duty, minimum rest, accommodation thresholds — handled automatically
Land, log your times, know your earliest next report instantly
WHAT DUTY DO I HAVE REMAINING
Real rolling 7/14/28-day totals, so today's numbers show exactly what's left for tomorrow
JUST OPEN IT
No account, no login, no setup
Your duty record stays on your device — nothing sent anywhere, nothing shared
High-contrast mode for bright cockpit light
Reference tool only — always confirm against your Operator's approved FTL scheme.
Built by the team behind High Performance Pilot.
