For the decade starting in 2017, Aviation Week predicts 11,346 deliveries of business aircraft (jets or not) valued at $250.1 billion, with a fleet growing from 31,864 aircraft to 36,702 aircraft (64% in North America): 4,838 more at an average annual growth rate of 1.6%, with 5,835 retirements. For the coming five-year period, Textron Aviation should lead the market with a 22.8% market share, followed by Bombardier with 20.4%, Embraer with 16.6%, Gulfstream with 15%, Dassault with 8.4% then the rest of manufacturers with 16.9%. There should be 22,190 Engine deliveries, led by the Honeywell HTF7000, Williams FJ44, Pratt & Whitney Canada PT6A Medium, Pratt & Whitney Canada PW300 and the Pratt & Whitney Canada PT6A Large. The average utilization should be 365 flight hours per aircraft per year.
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.
