How Fast Do Helicopters Fly? Average Speeds by Type and Model

Most helicopters cruise between about 110 and 165 knots, which is 125 to 190 mph (200 to 305 km/h). A two-seat piston trainer like the Robinson R22 sits at the bottom of that range at up to 96 knots (110 mph). A medium twin like the Leonardo AW139 sits at the top at 165 knots (190 mph).

If you want one number for an average helicopter speed, use 140 knots, or about 161 mph (259 km/h). That is the median published cruise speed of the 20 civil helicopters in our model table below.

The official speed record for a conventional helicopter is 249 mph (400.87 km/h), set by a Westland Lynx in 1986. Experimental compound helicopters with extra propellers have since flown faster, up to 255 knots (293 mph) in level flight.

Helicopter speed by model

Here are the published cruise speeds of 20 civil helicopters in production, from the slowest trainer to the fastest medium twin. Each figure is the one the manufacturer prints, with its label.

The slowest machines are the piston helicopters that most pilots learn on. They are light, cheap to run and built for training and short hops, not for speed.

Turbine power adds speed quickly. The single-engine Airbus H125 reaches a fast cruise of 136 knots (157 mph), more than 25 knots quicker than the piston R44.

The fastest civil helicopters in production are the medium twins used for offshore, rescue and VIP flying. Leonardo lists the AW139 at a 165-knot (190 mph) max cruise, and the Bell 429 and Sikorsky S-76D both reach 155 knots (178 mph).

Bigger is not always faster. The heavy Sikorsky S-92A+ lists a maximum cruise of 151 knots (174 mph), 14 knots slower than the AW139.

Cruise speed, top speed and VNE: why the numbers disagree

Search for one helicopter’s speed and you will often find three different numbers. They are usually all correct, because they measure different things.

• Recommended or long-range cruise: the efficient speed a pilot flies to stretch fuel.
• Max or fast cruise: the highest speed the helicopter can hold in level flight at maximum continuous power.
• VNE (never-exceed speed): the red line on the airspeed indicator, which the pilot must never pass.

The Airbus H225 shows the gap clearly. Airbus lists a recommended cruise of 142 knots (163 mph) and a never-exceed speed of 175 knots (201 mph).

Airbus even prints two figures for the H160 on its own pages: a recommended cruise of 138 knots and a fast cruise of 150 knots. Compare an Airbus recommended cruise with a Leonardo max cruise and the Leonardo will look faster than it really is.

Weight and altitude matter too. Most figures above are quoted at maximum gross weight, so a lightly loaded helicopter can cruise a little faster than its brochure number.

Why helicopters cannot fly faster

The limit is the main rotor itself. As a helicopter flies forward, one side of the rotor disk is moving into the wind and the other side is moving away from it.

The FAA’s Helicopter Flying Handbook calls the result dissymmetry of lift. The advancing blade meets faster air and makes more lift, while the retreating blade meets slower air and makes less.

The retreating blade has to work at a high angle of attack to make its share of lift. At high forward speed it eventually stalls, which the FAA calls retreating blade stall, and the pilot feels vibration, a nose pitch-up and a rolling tendency.

That is why every helicopter has a never-exceed speed. According to the FAA, retreating blade stall also arrives at a lower airspeed as altitude increases, so VNE usually falls the higher a helicopter climbs.

Engineers work around the limit by unloading the rotor. Compound helicopters add propellers for thrust, and some add short wings for lift, which is how the experimental machines below fly so much faster.

How long does a helicopter take to fly 100 miles?

At typical cruise speeds, a helicopter covers 100 miles in about 30 to 50 minutes. Here is the flying time for three common helicopters at their published cruise speed.

Real trips take longer than the table shows. Wind can add or subtract many minutes, and a light helicopter may need a fuel stop on a 300-mile trip once legal reserves are counted.

Range is the other half of the question, and it varies just as widely. Our guide to how far helicopters can fly covers it model by model.

How fast do military helicopters fly?

Military helicopters fly at roughly the same speeds as civil medium and heavy twins, because the same rotor physics applies. The US types below all publish figures between 139 and 170 knots.

Boeing lists the CH-47F Block II Chinook at a cruise speed of 157 knots (181 mph) and a maximum speed of 170 knots (196 mph).

The US Army’s 2012 Weapon Systems Handbook gives the UH-60M Black Hawk a cruise speed of 152 knots (175 mph). Boeing lists the AH-64E Apache’s maximum level flight speed as “150+ knots” (173 mph or more).

Bell gives its AH-1Z Viper attack helicopter a cruise speed of 139 knots (160 mph). You can compare these and other gunships in our guide to attack helicopters.

Outside the US, India’s HAL Dhruv Advanced Light Helicopter has a maximum cruise speed of 250 km/h (155 mph), according to India’s Ministry of Defence. The Leonardo AW101 lists a 150-knot (173 mph) max cruise.

For the wider picture of what each type does, see our guide to the types of military helicopters.

The fastest helicopters ever flown

The official record belongs to a modified Westland Lynx. On August 11, 1986, Westland chief test pilot Trevor Egginton flew G-LYNX at an average 400.87 km/h (249.1 mph) over a straight course near Glastonbury, England, setting the FAI absolute speed record for helicopters.

Compound helicopters have flown faster since, in runs their makers called unofficial records. The X3 used two propellers mounted on short wings beside its main rotor. Sikorsky’s X2 reached 250 knots (288 mph) in level flight on September 15, 2010, and the Eurocopter X3 reached 255 knots (293 mph) in level flight on June 7, 2013.

Airbus’s Racer demonstrator, which builds on the X3’s layout of a main rotor plus two lateral rotors, hit 420 km/h (227 knots) on June 21, 2024, less than two months after its first flight. Its target is a fast cruise of 220 knots (253 mph), well above any production helicopter in our tables.

Tiltrotors go faster still, but they are not helicopters. Bell’s V-280 Valor reached its 280-knot (322 mph) cruise speed in 2019. Its US Army derivative, named the MV-75 Cheyenne II in April 2026, still had its first test aircraft under construction that summer.

Are helicopters faster than airplanes?

Not usually. A fast helicopter can outrun a light piston airplane like the Cessna Skyhawk, but no helicopter comes close to a jet airliner.

Helicopters trade speed for the ability to hover, land on a rooftop or a ship deck, and lift loads on a hook. Our guide to how fast airplanes go covers everything from trainers to airliners.
