Frequently Asked Questions

At what stage length do turboprops lose their economic advantage over regional jets?

Turboprops hold an overwhelming 35% to 45% fuel advantage on routes under 300 NM. Between 350 and 450 NM, the higher cruise speed of regional jets begins offsetting fuel costs through higher aircraft daily utilization and reduced crew block hours.

Why are turboprops so much more fuel-efficient on short-haul flights?

Turboprop propellers accelerate a massive mass of air at lower velocity compared to turbofans, yielding superior propulsive efficiency at speeds below Mach 0.60 and lower climb fuel burn to typical cruise altitudes of 18,000 to 25,000 feet.

How does turnaround time differ between turboprops and regional jets?

Turboprops typically feature integrated passenger airstairs and lower cargo hold sill heights, enabling 20 to 25 minute unassisted gate turns at regional airfields without ground power or jet bridge infrastructure.

What is the passenger comfort trade-off between the two propulsion types?

Modern regional jets offer cruise altitudes of 35,000 to 41,000 feet (above turbulent weather systems) and quieter cabins. Modern turboprops utilize active noise and vibration suppression (ANVS) to mitigate interior propeller drone.
