Beechcraft King Air 360 Er vs Bell 525 Relentless vs Cessna Citation Xls vs Daher Tbm 960
The Beechcraft King Air 360ER is a twin‑turboprop utility/business aircraft, typically configured for about 6–9 passengers, with long endurance and a published maximum range around 1,800–2,000 nm depending on reserves and configuration. The Daher TBM 960 is a single‑engine high‑performance turboprop, usually seating about 4–6 passengers in executive comfort (up to 6–7 including pilot seats), with a maximum range roughly in the 1,400–1,700 nm class. The Cessna Citation XLS+ is a super‑midsize business jet, generally carrying about 7–9 passengers, offering faster cruise and a typical maximum range near 2,000–2,100 nm. The Bell 525 Relentless is a large, fly‑by‑wire helicopter aimed at offshore and corporate roles; it commonly accommodates about 12–16 passengers (higher in utility layouts) with a range roughly around 500–600 nm. Overall, the XLS+ leads on jet speed with solid range, the King Air 360ER emphasizes flexibility and runway access with strong endurance, the TBM 960 prioritizes efficiency for smaller groups, and the Bell 525 trades range and speed for vertical‑lift access.
