Sky DutyFlight Department Software for Part 91 Operators
Sky Duty is the system of record for a Part 91 flight department — one board for the whole fleet, crew coordination, maintenance status, and trip costs in a single offline-first iPhone and iPad app. Run the ground operation from one place, without stitching together three tools and a spreadsheet.
Built for private and corporate Part 91 operations
Part 91 is your own flying — a private owner or a corporate flight department operating one to ten aircraft, not for hire. The actual job is coordination: is that tail available Thursday, is it out of annual, who is current to fly it, and what did the last trip cost. Answering those questions usually means a whiteboard, a shared calendar, a maintenance program, and an expense spreadsheet nobody wants to own. Sky Duty answers all four from one app.
It is not an EFB. Sky Duty does not do charts, approach plates, or in-flight navigation, and it does not replace the app you fly with. It is the ground operation — the corporate flight department software that keeps the schedule, the logbook, maintenance, expenses, and crew referencing the same records, offline-first, on iPhone and iPad.
One board for the whole fleet
Set the operation type to Part 91 and put every aircraft on one Gantt board — rows for tails, color-coded bars for trips, a live "now" line across the day. Build multi-leg trips, assign crew, and let conflict detection flag a double-booked tail before it becomes a problem.
- Aircraft rows with color-coded trip bars — the whole fleet at a glance
- Day, 3-day, week, and month views
- Multi-leg trips with conflict detection
- ICS calendar feeds so crew see assignments in any calendar app
Which means: the scheduling whiteboard and the shared spreadsheet stop being the source of truth — everyone works from the same board, on any device.

The right role sees the right slice
A Part 91 department is owners, dispatchers, line pilots, and mechanics — and they should not all see the same thing. Sky Duty ships built-in roles with a custom permission matrix and assigns PIC and SIC per leg, so a mechanic works the maintenance queue while a dispatcher runs the board, against the same records.
- Built-in roles: Owner, Admin, Dispatcher, PIC, SIC, and Mechanic
- Custom permission matrix, down to field level
- PIC and SIC assignment per leg
- Unlimited users at every aircraft tier
Which means: you can add the owner, the accountant, or a maintenance vendor without paying per seat or handing over the whole operation.

Know what is grounded before you schedule it
Squawks get reported with photos and routed to the right person. Inspections — 100-hour, annual, and custom intervals — count down against date, hours, or landings, with FAA certificate data auto-populated from the registry. A due, overdue, and grounded dashboard shows aircraft status before you dispatch.
- Squawks with photos, tied to the aircraft and flight
- Inspection countdowns by date, hours, or landings
- Due, overdue, and grounded status at a glance
- Full maintenance history per tail number
Which means: you see what is out of annual before you schedule it, instead of finding out on the ramp.

Every cost tied back to a trip
Snap a fuel or FBO receipt and Sky Duty extracts the merchant, amount, and date, then links it to the trip it belongs to. Multi-currency handles international legs, and expenses export to PDF with charts or CSV so the hand-off to your accountant is clean.
- Receipt scanning with automatic data extraction
- Expenses linked to the trip that generated them
- Multi-currency for international trips
- PDF and CSV export for accounting and reimbursement
Which means: the answer to "what did that trip actually cost" lives next to the trip, not in a shoebox of receipts.

A logbook that fills itself in
When a scheduled flight closes out, the digital logbook captures the leg — Hobbs, tach, PIC, SIC, and approaches — so nobody re-types a flight that was already on the schedule. Currency is tracked from the entries you log, and the whole logbook exports to PDF and CSV.
- Auto-fills from completed trips — no double entry
- Template-driven entries with the fields you actually use
- Currency tracked from logged flight time, landings, and approaches
- PDF and CSV export, plus 47,000+ airports worldwide
Which means: the same flight is never entered twice, and the department has an audit-ready record without the end-of-month catch-up.

Honest about the edges
Sky Duty is deliberately the ground operation, not everything. It is not an electronic flight bag — keep ForeFlight or your EFB for charts, weather briefings, and navigation. The weather shown on your schedule is for situational awareness only, not an official briefing. And while expenses export cleanly for your accountant, Sky Duty is not general-ledger accounting and does not integrate with accounting software.
Where another tool wins, we say so. See Sky Duty vs ForeFlight for where the lines are.
Part of your flight department system
This page is one view of the same app. Everything here — the schedule, the logbook, maintenance, expenses, and crew — is part of your flight department system, one offline-first app instead of five integrations bolted together.
One price, per aircraft, everything included
Sky Duty is $39 per month per aircraft, with a 14-day free trial and unlimited users. Every feature on this page is included at that price. Pricing per aircraft matches how a Part 91 department actually spends — the airframe drives the budget, not the number of people who log in to read the schedule. Operating 10 or more aircraft? See the pricing page or email sales@skyduty.com for volume pricing. The trial starts in the app.
