Learjet 31
The Learjet 31, introduced in 1990 by the American manufacturer Learjet, marked a pivotal evolution in the company's line of midsize business jets. Building on the success of the earlier Model 28/31 series, the 31 featured a stretched fuselage, increased fuel capacity, and upgraded avionics that extended its range to roughly 1,600 nautical miles. Powered by two Garrett TFE731‑5BR‑1C turbofan engines, the aircraft delivers a cruise speed of Mach 0.78 and a ceiling of 51,000 feet, allowing rapid, high‑altitude travel for up to eight passengers and two crew. The cockpit incorporated a Honeywell Primus 1000 glass display, a first for Learjet, which improved situational awareness and reduced pilot workload. Its reinforced wing design and modernized landing gear enhanced durability and runway performance, making the 31 suitable for both short‑field operations and long‑haul missions. Throughout the 1990s the Learjet 31 became a favorite among corporate operators, charter services, and medical‑evacuation teams, cementing Learjet’s reputation for combining speed, efficiency, and reliability. The model’s legacy endures as a benchmark for subsequent Learjet offerings and as a notable contributor to the expansion of private aviation worldwide.
