I noticed on my ticket that we’ll be flying on a propeller plane. My question then is, what is the difference (besides the obvious) between regular planes and propeller planes?
In your case, the propeller planes are turboprops. These planes have turbojet engines with a rotating propeller outside and they have more in common with the jet engines in large aircraft than with piston engines, which are commonly found in smaller aircraft.
Turboprop aircraft are mainly used for short-haul flights, typically up to 480km. The reason for this is that they travel more efficiently at lower speeds and consume less fuel over these distances.
The maximum altitude, as well as the optimum cruising altitude, for turboprops is -lower than for jet airplanes such as Boeing and Airbus.
Turboprops are better suited for takeoffs and landings on shorter runways because they are lighter and able to operate at lower speeds. Not only that, the propellers provide extra drag, which can help slow the plane right down over a short distance. For these reasons they are more likely to be used when flying in and out of smaller airports.
