Beechcraft King Air 360 vs Beechcraft King Air 360er vs Cessna Citation Latitude vs Cessna Citation Sovereign
The Beechcraft King Air 360 and 360ER are twin‑turboprop aircraft typically used for short to medium missions with strong short‑field capability and lower operating costs than jets. The King Air 360 generally offers about 1,800 nautical miles of range and typically seats around 6 to 9 passengers depending on configuration. The King Air 360ER is the extended‑range variant; it trades some payload flexibility for more endurance, reaching roughly 2,400+ nautical miles, with similar seating (often 6 to 9). The Cessna Citation Latitude is a midsize business jet, faster and optimized for longer stage lengths than turboprops, commonly offering about 2,700 nautical miles of range and typically seating 8 to 9 passengers (with maximum layouts higher). The Cessna Citation Sovereign+ is a super‑midsize jet with higher cruise speed and slightly longer legs than the Latitude in many profiles, around 3,000+ nautical miles, and commonly seats about 8 to 10 passengers. Overall, the King Airs emphasize versatility and runway access, while the Citation jets emphasize speed, altitude, and longer nonstop capability.
