Beechcraft Baron G58 vs Beechcraft King Air 260 vs Beechcraft King Air 360 vs Beechcraft Kingair Denali vs Gulfstream G280
The Beechcraft Baron G58 is a piston twin in the light personal/business category, typically suited to shorter trips with about 4–5 passengers in comfort (up to six seats) and roughly 1,000–1,300 nm range depending on power and reserves. The King Air 260 is a twin‑turboprop in the small utility/business class, commonly carrying about 6–8 passengers with around 1,500–1,700 nm range. The King Air 360 is a higher-end variant in the same turboprop family, emphasizing cabin comfort and capability, usually 6–9 passengers with a similar roughly 1,500–1,800 nm range. The Beechcraft King Air Denali is a newer single‑engine turboprop in the upscale single category, generally aimed at 6–8 passengers with about 1,500–1,600 nm range. The Gulfstream G280 is a super‑midsize business jet, built for longer, faster missions, typically seating about 8–10 passengers with around 3,600 nm range. Overall, capability steps up from Baron to King Air/Denali for payload and runway flexibility, and then to the G280 for true long-range jet travel.
