Beechcraft Baron G58 vs Diamond Aircraft Da62 vs Pilatus Pc 12 Ngx vs Piper M500 vs Piper M600 Sls vs Piper Seneca

The Beechcraft Baron G58 and Piper Seneca are classic piston twins, typically used for personal and light business travel; they generally seat about 5–6 passengers and offer midrange capability, with real-world ranges commonly in the ~800–1,300 nm class depending on load, power settings, and reserves. The Diamond DA62 is also a piston twin but emphasizes efficiency and modern avionics; it’s usually configured for 5–7 seats and often delivers similar or slightly better range than many legacy piston twins, commonly around ~1,000–1,200 nm. The Piper M500 and M600 SLS are single-engine turboprops aimed at owner-operators; they typically carry about 4–6 passengers plus a pilot and provide longer legs than piston twins, roughly ~1,000–1,500 nm, with the M600 SLS generally offering more useful load and capability than the M500. The Pilatus PC-12 NGX is a larger, higher-end single turboprop in the utility/light business category, commonly seating 6–9 passengers and stretching into ~1,500–1,800+ nm missions, with greater cabin, payload, and runway flexibility than the others.
