Learjet 28

Learjet · United States · first flew 1977 · light aircraft

The Learjet 28 was the first Learjet model to feature winglets, introducing the 'Longhorn' wing that became a defining visual element for later Learjet models. It offered improved range and fuel efficiency over its predecessors.

History

The Learjet 28 first flew in 1977 and introduced winglets to the Learjet line following aerodynamic research that showed their significant efficiency benefits. The Longhorn series (Models 28 and 29) demonstrated that winglets could improve range by over 6 percent. The design validated winglet technology that was subsequently adopted across the industry.

Variants

The Learjet 28 (single-pilot certified) and the closely related Learjet 29 (two-pilot certification required) formed the Longhorn pair; both shared the distinctive winglet-equipped wing.

Where you'll see it

The Learjet 28 served with corporate and charter operators primarily in North America; total production was small as the model was soon succeeded by the Learjet 35 and 36 series.
