Why use a turboprop instead of a turbofan?
Turboprops are more efficient at lower speeds since the prop can move much more air with a smaller turbine than the fan on a turbofan engine. The cowl around the turbofan’s large fan allows it to perform better than an open propeller at high speeds, but limits the practical size of the fan.

Is turboprop more efficient than turbofan?
In fact, turboprop engines are also more efficient than turbofan engines, but aircraft speeds using turboprop engines are typically lower than those of turbofan engines.
Are turboprops more reliable?
Turboprops are generally considered more reliable, offer higher efficiencies for their higher power outputs, and can yield much improved performance at high altitudes.
How reliable are turboprop engines?
Reliability. Between 2012 and 2016, the ATSB observed 417 events with turboprop aircraft, 83 per year, over 1.4 million flight hours: 2.2 per 10,000 hours. Three were “high risk” involving engine malfunction and unplanned landing in single‑engine Cessna 208 Caravans, four “medium risk” and 96% “low risk”.
Which is safer turboprop or jet?
Myth Busted: Turboprops are equally as safe as jet engines. In fact, turboprops and jets both have turbine engines and are virtually the same thing.
What are the advantages of turboprop?
Due to turboprop engines’ lighter weight, they can perform more efficient takeoffs than traditional jet engines. Turboprops also provide a clear advantage over jets in landing capability; due to the drag a propeller brings, turboprops can land on much shorter runway strips and stop very quickly.
Are turboprops more reliable than jets?
Both turboprops and jets are powered by turbine engines, so they are essentially the same thing and thus, are considered to be equally as safe.
What are the disadvantages of a turboprop?
Planes with turboprop engines are typically limited to a lower cruising altitude than jet engines, capping at around 25,000-30,000 feet. Because of this, turboprops are also more susceptible to turbulence, noise, and inclement weather.
Are turboprops more efficient than jets?
High Efficiency A turboprop engine is more lightweight than a jet engine and provides a higher power output per unit of weight. Turboprops excel at fuel efficiency in low altitudes, being able to attain high speeds with the ability to be more cost-efficient than jet flight.
Are turboprops quieter than jets?
The noise levels in the cabins of turboprop aircraft are typically 10 to 30 decibels louder than commercial jet noise levels. However, unlike jet noise the turboprop noise spectrum is dominated by a few low frequency tones.
