Learjet 55

The Learjet 55 "Longhorn" is a private jet manufactured by Gates Learjet. The introduction of the Learjet 50 series occurred at the 1977 Paris air show. The winglets on the Learjet 55 were developed and advanced by NASA. The winglets gave the 55 the nickname "longhorn." The construction of the Learjet 55 happened April 1978 only after extensive testing and work on the wing design which came, initially, from the Learjet 25. The Learjet 55 first flew on 19 April 1979. The first production aircraft were produced starting 18 March 1981.

Variants

55B 1986- Glass cockpit, improved take-off performance and
increased range.
55C 1987- New rear underfuselage design, delta fins.
This increased stability and reduced the landing speed.
55C/LR Held an extra 259 lb of fuel in the tailcone and
85 gallons behind the fuselage.
