Identifying features

Is this really the aircraft type in front of you?

Check off everything that applies to the aircraft you are looking at.

  • Five-blade main rotor on a large, elongated twin-engine helicopter
  • Open three-blade tail rotor – no Fenestron like the H135, H145 or H160
  • Wheeled landing gear instead of skids, like all large offshore helicopters
  • Long row of large, rectangular cabin windows on a smooth, elongated fuselage
  • Large cabin doors on the sides of the fuselage, with a flat cabin floor behind them
  • Mostly in eye-catching offshore colors or as a SAR aircraft with a rescue hoist above the door

Updated: October 2026 – A large, smooth helicopter with wheels instead of skids, five rotor blades and a long row of windows drones toward the coast: if you are out and about in northern Germany, the Netherlands or Belgium, that could have been an Airbus Helicopters H175. The “super-medium” helicopter of the seven-ton class is built for flights far out to sea and brings crews to drilling rigs and wind farms. In Hong Kong it flies rescue missions, and in China it exists as a twin of its own. Here you will learn how the H175 came about, how to recognize it and where you are most likely to get it in front of your lens.

What is the Airbus H175?

The H175 is a twin-engine multi-role helicopter of the seven-ton class. Airbus Helicopters positions it between the smaller H160 and the heavy H225. It was developed mainly for one market: transporting workers to offshore platforms. Long flight distances over open water, many passengers and high safety margins were therefore the requirements.

Two Pratt & Whitney Canada PT6C-67E turboshafts with about 1,776 shp each power it. Airbus cites a cruise speed of over 287 km/h, a range of 1,160 kilometers with standard tanks and an endurance of more than six hours. The maximum takeoff weight is about 7.8 tons, and the five-blade main rotor measures 14.8 meters in diameter.

Depending on the layout the cabin seats up to 18 passengers, up to four per row in the offshore layout. The cabin floor is flat, and Airbus puts the volume at 12 cubic meters plus about 2.3 cubic meters of baggage space. For emergency ditching the H175 has inflatable floats, which according to Airbus are certified up to sea state 6.

The cockpit houses the Helionix avionics, which Airbus also uses in the H145, H160 and other types. This includes a four-axis autopilot that strongly assists approaches to platforms and hovering on SAR missions. You can find more about the manufacturer itself on the page about Airbus Helicopters.

Development with AVIC: a European-Chinese chapter

The H175 is one of the few Western helicopters that was developed together with a Chinese partner from the start. On December 5, 2005, Eurocopter signed the development contract with the Harbin Aircraft Industry Group, which then belonged to AVIC II.

The tasks were clearly divided:

Area Airbus Helicopters (Eurocopter) Harbin (AVIC)
Role technical leadership, systems integration partner and manufacturer of large assemblies
Assemblies main gearbox, tail rotor, doors, glazing airframe, main rotor, intermediate and tail gearbox
Systems avionics, autopilot, hydraulics, electrics fuel system, flight controls, landing gear
Engines of its own version PT6C-67E (Pratt & Whitney Canada) Ardiden 3C / WZ-16 (Safran with AVIC Engine)
Designation EC175, H175 since 2015 originally Z-15, now AC352

The EC175 was publicly presented in February 2008 at Heli-Expo in Houston. The official first flight followed on December 17, 2009 in Marignane near Marseille, the large French plant of Airbus Helicopters near Marseille Airport. Time passed before certification: among other things, certification of the new avionics delayed the program by about two years. In January 2014 EASA granted type certification.

The Chinese variant, the AC352, went its own way. It flies with Ardiden 3C turbines, which Safran (then Turbomeca) developed together with AVIC Engine and which are designated WZ-16 in China. Its first flight took place on December 20, 2016. In 2014 Airbus Helicopters and Avicopter had agreed to split production into two separate final assembly lines.

Practical tip: do not mix up the twin

An AC352 looks confusingly like the H175. Outside China, though, you will hardly ever encounter it. If you photograph an “H175” in China, check the registration and the operator details before you log the sighting.

Entry into service and name change

The launch customer was NHV (Noordzee Helikopters Vlaanderen) from Belgium, which put the first aircraft into service over the North Sea in December 2014 and ordered 16 in total. One of the early aircraft first flew as PH-NHV in the Netherlands and was stationed in Den Helder, a hub for offshore flights to oil and gas platforms. In 2020 it moved to the UK and was registered there as G-NHVV.

In the course of the renaming of Eurocopter to Airbus Helicopters, the EC175 became the H175 in 2015. Airbus also advertises climb records: according to the manufacturer, an H175 reached 6,000 meters in 6 minutes and 54 seconds.

Not all major orders were also delivered. The offshore operator Bristow had ordered 22 H175s but canceled the order in early 2020 as part of its restructuring. In 2019 cracks were also found on two aircraft in the tail boom and vertical stabilizer; Airbus limited the maximum speed until the cause was clarified. The offshore market in particular depends heavily on oil and gas prices, which has dampened sales of the type for years. New momentum recently came from the lessor SKYCO, among others, which ordered six H175s in July 2025.

The three features that are enough to identify it

Large offshore helicopters often look alike from a distance: long, heavy, with wheels and many windows. For the H175, three observations help you.

Count the main rotor blades

The H175 has five main rotor blades on the Spheriflex rotor head. Four blades on a large twin point more to a Sikorsky S-92 or an older Super Puma.

Look at the tail

Unlike most current Airbus helicopters, the H175 has no Fenestron but an open tail rotor with three blades. That is a very good distinguishing feature against the H160, H135 and H145.

Fuselage and windows

The fuselage is long and smooth, with a continuous row of large, almost square windows. Below it sits wheeled landing gear. Super Puma descendants, by contrast, look more angular and taller.

As always, the final certainty comes from the registration. Offshore helicopters in the North Sea often carry Dutch (PH-), British (G-), Belgian (OO-) or Norwegian (LN-) registrations. How the system works is explained in the article Understanding aircraft registrations; for British registrations in particular, the guide British G registrations helps.

H175, H225, S-92 or AW189?

In the offshore world the H175 competes mainly with the Leonardo AW189, the Sikorsky S-92 and its own stablemate, the H225. For identification it is worth looking at the tail and fuselage shape. The finder helps you narrow it down.

Quick ID: large offshore helicopters

Three questions, one estimate. The registration remains the final authority.

Likely

Airbus H175

Five main rotor blades, a small open tail rotor and the smooth, long fuselage are the typical H175 look. If EC75 shows on the tracker, the case is clear.

Likely

Leonardo AW189 or Airbus H225

These two also have five main rotor blades and wheeled landing gear. The AW189 has a slimmer nose, the H225 the angular Super Puma fuselage. Check the registration.

Likely

Sikorsky S-92

Four blades and a bulky fuselage with a rear ramp point to the American competitor, which is also widespread in the North Sea.

If you want to get deeper into identifying rotorcraft, the guide How to identify helicopter types gives an overview of the most important features – from the tail rotor and blade count to the landing gear shape.

Where you will find the H175

The H175 is not a helicopter for the observation deck of a major airport. It works where the offshore industry and coastal rescue are at home.

North Sea offshore: Most European H175s fly on behalf of the oil, gas and wind energy industry. NHV, as the launch operator, was active with the type in Den Helder and in the UK, among other places. The bases are typically at smaller coastal airfields or at dedicated helicopter terminals of larger airports.

Search and rescue in Hong Kong: The Government Flying Service (GFS) is the launch customer of the SAR version, announced in 2015, and today operates seven H175s. The helicopters are based at Hong Kong Airport and fly rescue missions over the South China Sea, even in typhoons. If you are traveling to Hong Kong anyway, a look at the guide Plane spotting in Hong Kong is worthwhile.

Other operators: The H175 also flies for government agencies and corporate customers, partly with a VIP cabin. The Spanish air force has ordered H175s in VIP configuration, and Airbus markets its own military version with the H175M.

Place Chance of a hit Why
Offshore bases on the North Sea coast high Main market of the type, regular crew flights
Hong Kong Airport (GFS) high seven SAR H175s in service
Airbus plant Marignane medium Final assembly, testing and delivery flights
German inland commercial airports low ferry and maintenance flights rather rare

Fleets change all the time

Offshore contracts often run only a few years, and aircraft are shifted between operators and lessors. Before a targeted trip, check the operators’ current information and do not rely on old fleet lists.

Offshore helicopters usually transmit ADS-B data and are therefore easy to find on flight tracker services. How to search specifically for rescue, police and offshore flights is explained in the article Finding helicopters on a flight tracker.

Put type EC75 on your wish list

In Planetrack, put the H175 or individual registrations on your wish list and get notified by a sighting alert when they approach your airport. Planetrack is launching soon – join the waitlist.

Photo tips specifically for the H175

With helicopters, the shutter speed decides the picture. If a very short exposure freezes the rotor, the H175 looks as if it is hanging motionless in the air. Five blades forgive a bit more than four, because the rotor disc looks “full” sooner.

Show the rotor in motion

Expose much longer than for jets and start with values around 1/125 s. With clean panning the fuselage stays sharp while the blades blur.

Use the side profile

The long row of windows, the wheeled landing gear and the small tail rotor show to their best advantage in profile. Such perspectives suit takeoffs and landings at coastal airfields especially well.

Wind and light on the coast

Helicopters mostly take off and land into the wind. If you plan wind direction and sun position together, you will more often stand in the right light.

Shoot bursts

With long exposure times not every picture works. Shoot bursts and sort them out later.

The technique is the same as for propeller aircraft; details are in the guide Photographing propellers: the right shutter speed. You will find general tips about rotorcraft in the article Helicopter spotting. How to plan light and position in advance is shown in the article Planning around the sun position. With the sun position planner and the weather and wind data in Planetrack you see before the trip which direction light and approach come from.

H175M and government variants

Besides the offshore and SAR versions, Airbus offers the H175 as a VIP helicopter and as the military H175M. According to Airbus, the VIP cabin holds six to twelve passengers. Airbus offered the H175M to the British Air Force, among others, for its New Medium Helicopter program. Spain has ordered H175s in VIP configuration for its air force.

Military and government aircraft often carry their own identifiers instead of civil registrations and fly less predictably. What to keep in mind when photographing near military facilities is in the article Photographing military airfields: rules.

Common mix-ups and how to rule them out

It points to the H175 if …

  • you see five main rotor blades and a small, three-blade open tail rotor
  • the fuselage is long and smooth, with large rectangular windows
  • wheeled landing gear instead of skids sits under the fuselage
  • the tracking service lists EC75 as the type

Take a closer look if …

  • you only see the helicopter from below – then the H175, H225 and AW189 look very alike
  • you are photographing in China – there it could be the twin, the AC352
  • the livery belongs to an operator that flies several large types in parallel

It is not an H175 if …

  • a Fenestron sits in the vertical stabilizer – then more likely an H160 or H145
  • you only count four main rotor blades
  • the helicopter stands on skids
  • you recognize the angular fuselage of a Super Puma (H215)

Another candidate in the medium segment is the Leonardo AW139. It is somewhat smaller and lighter, also has five main rotor blades and wheeled landing gear, but looks shorter and stockier. If in doubt, a size comparison with people or vehicles nearby helps.

Conclusion

The H175 is a specialist: built for long flights over open water, with lots of room in the cabin and high safety margins. Its history as a joint project with AVIC makes it a special chapter in helicopter development, and its Chinese twin, the AC352, still creates potential for mix-ups. For spotters in Central Europe it is a rather rare but all the nicer encounter – most likely on the North Sea coast. Five main rotor blades, the small open tail rotor and the wheeled landing gear give you the type, the registration the confirmation.

Quick summary

Large, smooth fuselage, five main rotor blades, open three-blade tail rotor and wheels: that is the H175. Watch for offshore flights on the coast, expose a bit longer for a moving rotor and note the registration – then even this rare sighting becomes a clean entry.

Summary

  • The development contract between Eurocopter and the Harbin Aircraft Industry Group was signed in December 2005, and the EC175 was officially presented at Heli-Expo in 2008.
  • After its first flight in December 2009 and EASA certification in January 2014, the type entered service with NHV in December 2014 and has been called the H175 since 2015.
  • Typical missions are offshore transport in the North Sea, SAR missions (for example with the Government Flying Service in Hong Kong) and VIP and government tasks.
  • Blade count, tail rotor design and landing gear are enough to identify it; the registration and the code EC75 provide confirmation.

Frequently asked questions

Is the H175 the same as the EC175?

Yes. The helicopter was developed and certified under Eurocopter as the EC175. When Eurocopter became Airbus Helicopters, it received the new designation H175 in 2015. You will find both names in databases and registration registers.

What is the H175’s ICAO type designator?

The H175 is listed as EC75. The code recalls the original designation EC175 and shows up that way in flight plans and tracking services too.

What does China have to do with the H175?

The type is a joint development with the Harbin Aircraft Industry Group, a subsidiary of the Chinese aviation group AVIC. Harbin builds the airframe, main rotor, landing gear and fuel system, among other things, while Airbus Helicopters supplies the main gearbox, avionics and autopilot and is the systems integrator. In China the AC352 version is built with different engines; it first flew in December 2016.

Where do I see the H175 in Europe?

Mainly around the North Sea, where offshore operators fly crews to platforms and wind farms. The launch operator NHV had its aircraft stationed in Den Helder in the Netherlands, for example. At ordinary commercial airports the H175 is more of a rare encounter.

What is the difference between the H175 and the H225?

Both are large twins with a five-blade rotor and wheeled landing gear. But the H225 is heavier and comes from the Super Puma family with its typical, rather angular fuselage. The H175 is a new design with a smoother, longer fuselage, large rectangular windows and a three-blade tail rotor.

Is there a military version?

Yes, Airbus offers the H175M for military and government tasks; among other things it was offered to the UK for the New Medium Helicopter program. Spain’s air force has ordered H175s in VIP configuration. For spotters in Central Europe, though, the civil offshore H175 remains the more common variant.

May I photograph offshore helicopters at their base?

From public ground, usually yes. The bases themselves, though, are mostly behind fences on airfield grounds, and there the operator’s house rules apply. Respect barriers and ask if in doubt before you enter any grounds.

Collect the Airbus Helicopters H175, don’t just see it

Post a photo with registration, type, airport and spot, check off the type in your hangar and get an alert when a registration you are looking for lands. Planetrack is launching soon – join the waitlist and get early access.
