Notes:
The DC-9 was designed specifically to
operate from short runways and on short to medium range routes so that the speed,
comfort and reliability of jet
transportation could be extended to
hundreds of communities previously served
only by propeller-driven airliners.
There are five basic DC-9 versions,
designated Series 10, Series 20, Series
30, Series 40 and Series 50. Several
models in each series provide operators
maximum efficiency for diverse
combinations of traffic density, cargo
volume and route distances to more than
2,000 miles (3,218 km). All models use
variants of the reliable workhorse Pratt &
Whitney JT8D engine.
The Series 30 DC-9, is nearly 15 feet
longer than the Series 10, at 119.3 feet
(36.3 m), providing seats for up to 115
passengers and cargo space to 895 cubic
feet (25.3 m3). Series 30
wingspan was increased to 93.3 feet (28.4
m), and a high-lift wing system of leading
edge slats gives the Series 30 excellent
short-field performance. The first of the
type began airline service in February
1967.
Most of the Series 30s are powered by
either JT8D-7 or JT8D-9 engines. Others
are equipped with JT8D-11 or the JT8D-15,
with 15,500 pounds of thrust. The Series
30 is the most widely used member of the
DC-9 family, accounting for approximately
60 percent of the entire fleet.
