Turboprop vs Jet: Learn Their Advantages and Disadvantages

One of the big debates when it comes to selecting an aircraft is the choice of turboprop vs jet engine. Light jets are more common in private aviation, but Forbes recently reported that charter activity for turboprops had increased by 8% year-over-year.

Some pilots staunchly prefer one type of aircraft while others see advantages and disadvantages of each. These pilots have come to believe that the best aircraft is the one that is properly suited for the type of flight you are planning to take.

How do you know which option is best for you? Let’s look at the top 3 advantages and disadvantages of turboprops and jets, then talk about what flights each type of aircraft is optimized for.

Turboprop Advantages

1.      More efficient & more cost-effective for short distances

A turboprop engine is more lightweight than a jet, giving it better performance during takeoff. It runs more efficiently while providing a higher power output per unit of weight than a jet. Expect optimum fuel efficiency when flying at low altitudes (ideally below 25,000 feet).

2.      Able to take off and land on shorter and non-concrete runways

If your travel plans include destinations with shorter, less highly improved runways, a turboprop has a clear advantage over a jet. Turboprops can land on runways as short as 3,200 feet compared to an average jet minimum of 5,000 feet. Turboprops can also handle the grass airfields that jets must avoid. This means that with a turboprop, you can get into some of the most hard-to-reach airports.

3.      Lower charter, insurance, operation and maintenance costs

The overall cost of a turboprop is lower than a jet both for chartering and for owning. Fewer moving parts in a turboprop engine make it more reliable and less likely to require extensive maintenance. Since turboprops burn less fuel per hour than jets, their hourly operation cost is lower.

Turboprop Disadvantages

1.      Slower cruising speed

Since turboprops have a slower maximum efficient cruising speed – up to an average of 300 knots indicated airspeed (KIAS) depending on the aircraft – expect your overall flight time to be longer than it would be with a jet. Although the hourly cost of a turboprop is lower, since the slower speed makes the flight time longer, at some point with a longer distance flight, the cost savings will be offset.

2.      Lower cruising altitude

Turboprops typically have an altitude ceiling of 25,000-30,000 feet. If you run into turbulence or inclement weather conditions at this altitude, a turboprop won’t be able to avoid them by climbing to a higher altitude like a jet can. This may make for a bumpy and uncomfortable ride.

3.      Shorter range

Turboprops’ slower cruising speed and lower cruising altitude equates to shorter range even factoring in improved efficiency. This means that while turboprops are great for short and mid-range flights, they are not designed for long-distance travel. Expect an average range of around 1,000-1,300 miles.

Jet Advantages

1.      Capable of cruising at higher altitudes

The average light jet will cruise at an altitude of 41,000 feet and is capable of a maximum altitude of 45,000 feet. This is substantially higher than the turboprop’s 30,000-foot ceiling and can mean the difference between a smooth, comfortable flight and a flight marred by repeated patches of turbulence.

2.      Faster and quieter

Expect to arrive at your destination faster in a jet than you would in a turboprop. Light jets have average cruising speeds of between 370 and 450 knots. The jet engine design also provides a quieter cabin than a turboprop.

3.      Longer range

Thanks to their faster cruising speeds and ability to fly at higher altitudes where their efficiency is improved, light jets are capable of an extended range from 1,600 to over 2,000 miles. This makes them the aircraft of choice for mid-to-long-range flights.

Jet Disadvantages

1.      Less efficient & less cost-effective for short distances

Jets are at their most efficient when operating at faster speeds and higher altitudes. During takeoff, at slower speeds, and at lower altitudes, turboprops are more efficient. This means that for short flights with less time spent at cruising altitude, a jet will be less efficient and will cost more per hour than a turboprop.

2.      Require longer, concrete runways

Jets may do well with flying into standard airports, but if you want to explore a more remote area with a short runway or unimproved grass airstrip, you will be out of luck with a jet. On average, jets need a paved runway at least 5,000 feet long. By contrast, many turboprops can land on a 3,200-foot grass stip.

3.      More expensive to charter, insure and maintain

In 2016, the Aircraft Owners and Pilots Association (AOPA) published a detailed breakdown of hourly operating costs for both jets and turboprops. Across the board, the jet aircrafts were consistently more costly than the turboprops. The additional moving parts and relative complexity of a jet engine vs a turboprop make maintenance costs higher as well.

Turboprop vs Jet – Which should I choose?

Armed with knowledge of the pros and cons of both turboprops and jets, we can understand why experienced pilots see a purpose for each type of aircraft.

Let’s wrap up with an overview of the specific types of flights that each aircraft is best designed for.

What type of flights is a turboprop best for?

  • Short to mid-range flights
  • Flights that require landing on a short and/or grass strip runway
  • Flights that are as inexpensive as possible

What type of flights is a jet best for?

  • Mid-to-long-range flights
  • Flights for which the shortest possible flight time is preferred
  • Flights for which reduced cabin noise and turbulence are primary concerns
