The fundamental difference
A turboprop uses a gas turbine to drive a propeller, while a business jet produces its thrust directly through jet reaction. This technical difference drives almost every other selection criterion: cost, speed, range and operational flexibility.
Operating cost comparison
A turboprop generally burns 30 to 50% less fuel than a jet of comparable power, and its maintenance is often simpler and less expensive. At purchase, a recent used turboprop generally costs less than an equivalent light jet of the same age and flight hours.
| Criterion | Turboprop | Light jet |
|---|---|---|
| Fuel burn | Lower | Higher |
| Cruise speed | 450-550 km/h | 700-850 km/h |
| Used purchase price | Generally lower | Generally higher |
| Minimum runway required | Often shorter | Longer |
Speed and range
The business jet has a clear edge over long distances: its higher cruise speed significantly cuts flight time beyond 800 to 1,000 km. For shorter trips, the flight-time gap between the two aircraft types often stays marginal once taxi and climb time are factored in.
Access to short runways
Thanks to their better short-field takeoff and landing performance, turboprops often reach smaller airfields that jets cannot serve. This is a decisive criterion for an operation that needs to reach remote areas or unpaved runways.
Which aircraft for which use
A turboprop suits frequent regional trips, access to short or unprepared airfields, and a controlled operating budget well. A business jet is preferable for long distances, cabin comfort on multi-hour flights, and the image associated with this type of aircraft for intensive professional use.
