A common debate when selecting an aircraft is the choice between a turboprop or jet engine. Jet engines are more common in private aviation, but turboprops are slowly increasing in popularity. In this blog, we will look at the advantages and disadvantages of both turboprop and jet engines.
First, let's look at the advantages of turboprop engines. For one, they are more efficient and cost-effective over short distances. They are more lightweight than jet engines, giving them better performance during take off. Additionally, they run more efficiently while providing a higher output per unit than jets. A second advantage of turboprops is their ability to take off and land on shorter, non-concrete runways. Turboprops are able to land on runways as short as 3,200 feet, while average jets require at least 5,000 feet. Furthermore, turboprops can land on grass or dirt airfields that the more sophisticated jet aircraft cannot withstand. Finally, turboprops offer lower charter, insurance, operation, and maintenance costs. Despite these benefits, turboprops are not without their drawbacks. When compared to jet engines, turboprops have slower cruising speeds, lower cruising altitudes, and shorter ranges.
Jet engines also have many unique advantages. The three most significant of these are that they can cruise at higher altitudes, are faster and quieter, and have longer ranges. The average light jet can cruise at an altitude of 41,000 feet, while a turborop’s ceiling is generally around 30,000 feet. This means jet engines can fly above poor weather for a smoother journey. They are also faster than turboprops, with an average cruising speed between 370 and 450 knots. Jet engines designs also provide a quieter cabin than turboprops. Finally, thanks to their faster cruising speeds and ability to fly at higher altitudes, jet engines are capable of ranges greater than 2,000 miles, while turboprops have an average range between 1,000 and 1,300 miles. The primary disadvantages of jet engines are that they are less efficient over short distances, they require longer, concrete runways, and are more expensive to charter, insure, and maintain.
Ultimately, the better engine comes down to how it will be used. Turboprops are best for short and mid-range flights, flights that require landing on a short runway, and flights where cost is an important factor. Jet engines are better for mid to long-range flights and flights where turbulence, cabin noise, and flight time are concerns.
