Two years after the Learjet 55 B, the Learjet 55 C was released. Naturally, this aircraft model was more progressive than its predecessor. A special feature of the Learjet 55 C is the equipment with "Delta keels" behind the fuselage. This innovation has improved the stability of the aircraft at all speeds. Also, this equipment reduced the landing speed and thereby eliminated the need for one of the pilots. The new model quickly gained respect among businessmen and ordering a Learjet 55 С became commonplace.
The aircraft had good maneuverability and could move on short runways. The improved cabin had its own comfort for long flights. Thanks to these indicators, many businessmen wanted to rent a Learjet 55 С. Later, Learjet 55 С / ER and Learjet 55 С / LR replaced the Learjet 55 С.
