Last year was a good one for general aviation manufacturers. According to the airframers trade association, the General Aviation Manufacturers Association (GAMA), global airplane shipments increased 4.7 percent in 2018, to 2443. Billings-what you and I pay for a new aircraft-increased 1.5 percent, from $20.2 billion to $20.6 billion. Meanwhile, worldwide rotorcraft shipments also rose-by 5.4 percent-from 926 to 976 units. The only disappointment in the year-end was that rotorcraft billings decreased slightly, by 0.7 percent, possibly reflecting growing demand for less-expensive training helicopters.
