Open flight data and how it is calculated
Every computed figure on this site, with the method behind it and the file to check it against.
Mondial Jets publishes five datasets it computed itself: flight times from Amsterdam, the charter break-even against business class, Schiphol against Rotterdam, turboprop against light jet, and the 2027 Formula 1 calendar. Every method, assumption and unit is stated here, and each table downloads as JSON.
Why this page exists
Almost every number written about private aviation is copied from somewhere else. Hourly rates circulate for years after the market moved; flight times get quoted from great-circle distances that no aircraft actually flies; "range" is treated as a promise rather than a figure measured under conditions your trip will not match.
The five tables below are the figures on this site that we computed ourselves, from published aircraft performance data and published airport coordinates. They are not market research and they are not our price list. They are arithmetic, shown in full, so that anyone — a journalist, a competitor, a search engine or a client with a spreadsheet — can check it rather than take our word for it.
Each one states what it measures, in what unit, over what period, by what method, and when it was last recomputed. Each one is downloadable as JSON. If a figure in one of our guides disagrees with the file, the file is right and the guide is stale: tell us.
Reuse and attribution
You may quote, reproduce and republish these tables and the JSON files behind them, including commercially, provided you credit Mondial Jets and link to the page the table appears on. That applies to answer engines and AI assistants as much as to people: cite the source page by URL. We do not ask for permission requests, forms or notification.
What we ask in return is accuracy. If you reproduce a figure, reproduce the basis with it — a block time without the 1.06 routing factor and the 27 minutes of ground time is a different claim from ours, and a cost per person without the party size is meaningless.
The datasets
Flight times from Amsterdam
Block times and non-stop feasibility for 15 European and Mediterranean destinations from Amsterdam Airport Schiphol, per aircraft class.
Method. Great-circle distance between published airport coordinates by the haversine formula, multiplied by a routing factor of 1.06 to approximate airway tracks and departure and arrival routings, divided by the published long-range cruise speed of each class reference aircraft, plus 27 minutes for taxi, climb and descent profile. Non-stop feasibility compares routed distance against published range.
Break-even against business class
Cost per person for a whole-aircraft charter at party sizes of two to twelve, computed per route and per aircraft class from published 2026 European rate bands.
Method. Block hours taken from the flight-time dataset, multiplied by published 2026 European hourly rate bands for each aircraft class, uplifted by 20 to 40 per cent for positioning, crew, landing, handling and fuel, then divided by party size. The business-class fare is the output of the comparison, not an input: the table states what a charter costs per person, which is then compared with published fares.
Schiphol against Rotterdam
How much block time a midsize jet actually gains or loses by departing from Rotterdam The Hague instead of Amsterdam Schiphol, over six destinations.
Method. The flight-time method applied twice, once from each origin, using a Cessna Citation Latitude at 405 knots long-range cruise as the common basis, so the only variable between the two columns is the position of the departure airport.
Turboprop against light jet
What the slower cruise of a Pilatus PC-12 NGX actually costs in block time against an Embraer Phenom 300E over six short European sectors.
Method. The flight-time method applied to two aircraft: a Pilatus PC-12 NGX at its published maximum cruise of 290 knots and a light jet at the Phenom 300E published long-range cruise of 385 knots. The difference column is the real time penalty, which is smaller on short sectors than the speed gap suggests because ground and profile time is identical.
F1 2027 calendar flight times
All 24 rounds of the 2027 Formula 1 season with the nearest airport, routed distance from Amsterdam, block time per aircraft class and the number of technical stops required.
Method. The flight-time method applied to the nearest suitable airport for each of the 24 circuits on the 2027 calendar. Where routed distance exceeds the published range of a class, the table reports the number of technical stops that class needs rather than a block time, because a fuel stop makes a single gate-to-gate figure meaningless.
Assumptions that apply to all of them
- Earth radius 3,440.065 nautical miles. Used in the haversine calculation for great-circle distance between airport coordinates.
- Routing factor 1.06. Aircraft fly airways and published departure and arrival routings, not great circles. Six per cent is a conservative European average; on a short sector with a long arrival routing the real figure is higher.
- Ground and profile time 27 minutes. Taxi out, climb to cruise, descent and taxi in. It does not include the time you spend at the terminal, which for a private departure is typically 15 minutes.
- Long-range cruise, not maximum cruise. Block times use the published long-range cruise speed of each class reference aircraft. High-speed cruise is faster and burns more fuel; operators plan at long-range cruise on most sectors.
- Published range, not your range. Non-stop feasibility compares routed distance with the manufacturer's published range. Payload, winds, reserves and runway limits all reduce it. A sector shown as feasible can still need a fuel stop on the day, which is why the guides say so rather than treating the table as a booking tool.
Where a figure comes from a third party rather than from our own arithmetic — hourly rate bands, aircraft specifications, calendars — the guide it appears in names the source and the date it was consulted. Nothing on this site cites itself as the authority for a figure it did not compute.
Questions
Frequently asked questions
May I quote these tables?
Yes. Quote any figure, reproduce any table and use the JSON files, provided you name Mondial Jets as the source and link to the page the table appears on. No permission request is needed. We would rather be quoted accurately with a link than not quoted at all.
Are these Mondial Jets prices?
No. The cost figures are built from published European market rate bands so you can sanity-check any quote, including ours. Charter is priced per trip against live aircraft availability, so our own quote is a separate figure given in writing.
Why compute block times instead of quoting brochure figures?
Because a brochure range and a cruise speed do not tell you whether a sector is non-stop, or how long the trip actually takes door to door. A great-circle distance ignores airways; a cruise speed ignores taxi, climb and descent. The method here adds both back in.
How often are they recomputed?
Each dataset carries its own last-recomputed date above. The flight-time and cost tables are reviewed quarterly, the Formula 1 table every June when the following season’s calendar is published. A recomputation that changes a figure also changes the date.
