由於商務噴射機的價格昂貴,分數擁有權(Fractional Ownership)是指有意購買商務噴射機的買主,不需購整架商務噴射機。透過如Netjets或是Flex Jet專門進行分數擁有權的商務噴射機公司,買主可以購買1/4、1/8或其它比例的商務機擁有權,而由商務噴射機公司來進行操作-包括飛行及維修。參加分數擁有權計劃的顧客,每個月可有固定時數的飛行。由於操作分數擁有權的商務噴射機公司,擁有許多飛機,因此顧客雖然擁有某架飛機的擁有權,但並不一定搭乘擁有的飛機。因此參加分數擁有權的計劃,顧客是以分擔商務噴射機公司購機和操作成本,以較低廉的價格,來享受商務噴射機飛行服務,但是就因為每個買主只擁有"部分所有權"而且並非天天都需要用到飛機,所以需要飛行得事先預約,再由商務噴射機公司安排飛機和空勤組員。[2]
Equipment trust certificate (ETC): Most commonly used in North America. A trust of investors purchases the aircraft and then "leases" it to the operator, on condition that the airline will receive title upon full performance of the lease. ETCs blur the line between finance leasing and secured lending, and in their most recent forms have begun to resemble securitization arrangements.
Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
