The owner-flown M600/SLS against the utility-focused PC-12, a choice of price and simplicity against cabin, cargo door and versatility.
The intuition that the smaller aeroplane must be the more flexible one does not survive this pairing: the PC-12 gets into shorter runways than the M600 while carrying more, and it does it with a cargo door the Piper has no answer to. What the M600 offers instead is a lower cost of entry and of ownership, six seats that are enough for most owner-flown trips, and Garmin Autoland as a standing safety argument. Its short production run before the M700 arrived cuts both ways on used value. The M600 suits an owner who flies themselves with family aboard; the PC-12 earns its premium when the aeroplane has to change roles between trips.
The table below uses the same versioned PlaneFit dataset as the Finder. Prices and operating costs are planning estimates, not quotations.
Choose the M600/SLS when an owner-pilot normally carries a small party from paved airports and values a smaller operating footprint plus the HALO safety package. It works best when the cabin and baggage are proven against the normal manifest, not the maximum seat count.
Choose the PC-12 NGX when the mission genuinely needs its larger cabin, cargo access, payload flexibility or ability to serve more demanding airfields. Those capabilities can justify the larger acquisition and support commitment when the aircraft changes roles between passenger and utility trips.
Neither is appropriate where company policy, insurer terms or the route requires two engines. A twin turboprop or charter solution is the correct comparison when redundancy is a non-negotiable operating requirement rather than a preference.
The planning model cannot price crew policy, programme enrolment, downtime, regional service support or a particular cabin configuration. Manufacturer figures are reference-condition values; approved performance and a current quotation govern the actual mission.

A factual first pass. Mission, condition and configuration can outweigh a brochure advantage.
They do not cross. The Piper M600/SLS is the cheaper of the two at every utilisation from zero to 300 hours a year, on purchase and running cost together, so there is no break-even point to find. That is worth knowing plainly: on cost alone this is not a trade-off, and the case for the other aircraft has to be made on mission, cabin, speed or access rather than on eventual savings.
| Five-year cash, including purchase | Piper M600/SLS | Pilatus PC-12 NGX | Difference |
|---|---|---|---|
| 40 h / year | $4.15m (€3.85m) | $6.82m (€6.32m) | $2.67m (€2.47m) to Piper M600/SLS |
| 100 h / year | $4.44m (€4.11m) | $7.23m (€6.69m) | $2.79m (€2.58m) to Piper M600/SLS |
| 200 h / year | $4.91m (€4.55m) | $7.9m (€7.32m) | $2.99m (€2.77m) to Piper M600/SLS |
The gap widens as utilisation rises, which is the part a headline price comparison hides. Every figure uses the same planning model as the rest of the site: indicative market prices, a fixed annual base and a direct hourly cost, before financing, depreciation and tax.
Advertised range is a still-air, best-case number. With 4 people aboard and realistic reserves, plan on about 1,111 nm from the Piper M600/SLS against 1,208 nm from the Pilatus PC-12 NGX. On a return trip without refuelling, that is the radius that decides which destinations are on the list at all.
Against the 28,815 airports in the PlaneFit database that publish a runway length, the Piper M600/SLS has enough runway at 18,571 of them and the Pilatus PC-12 NGX at 20,678, comparing each aircraft’s take-off requirement of 2,635 ft and 2,487 ft against the longest runway on the field.
This is a planning comparison, not a statement that any particular operation is legal or advisable. It ignores surface, slope, elevation, temperature, obstacles and how heavily the aircraft is loaded, all of which extend the requirement. It also compares take-off distance only: landing distance is frequently the binding constraint and PlaneFit does not hold approved landing distances, so a field in these counts is not necessarily a field you can get back out of, or into.
Nothing separates them here. Both require a type rating, a complex airplane endorsement, a high-altitude training, so a pilot qualified for one is qualified for the other.
