Bombardier Challenger 650

Updated: October 2026 – On the business aviation apron stands a white jet with a T-tail and two engines at the rear. It is no longer than the slim super-midsize jets next to it, yet it looks much bulkier, almost as if someone had squashed a regional jet. Very likely it is a member of the Challenger 600 family, and if it is a recent one, a Bombardier Challenger 650. Here you’ll learn how to recognize the type, why you can hardly tell it from the 605 on the outside, and where to get it in front of your lens in the German-speaking world.

What is the Bombardier Challenger 650?

The Challenger 650 is a twinjet large-cabin business jet from the Canadian manufacturer Bombardier. It is the latest stage of a family that began in the late 1970s at Canadair as the Challenger 600. Bombardier later developed the CRJ100/CRJ200 regional jet from the same basic design – hence the wide, almost airliner-like fuselage that shapes the whole family.

Bombardier unveiled the 650 on October 19, 2014 at the NBAA show in Orlando. Until then, the project had run internally as the Challenger 605 “NG,” the next generation of the 605. The launch customer was NetJets: the fractional provider had already signed a firm order for 25 aircraft plus options on 50 more in 2012. In December 2015, NetJets took delivery of the first Challenger 650; it was also the 1,000th Challenger ever delivered. Bombardier announced European certification by EASA in March 2016.

Legally, the 650 is not a new type. Like the 604 and 605, it runs under the type designation CL-600-2B16 and in flight plans under the ICAO type designator CL60. For you as a spotter, that has a clear consequence: neither the type code nor the silhouette tells you the exact variant. The registration does.

What the 650 changes compared with the 605

The Challenger 650 is a refresh, not a new design. Bombardier started where customers feel the difference: in the cabin, the cockpit and takeoff performance.

Cabin: The interior was redesigned and follows the design and ergonomics of the Challenger 350. Seats and galley are new, plus a cabin management system, large HD displays, audio and video on demand, and Bluetooth and internet connectivity.

Cockpit: The Bombardier Vision Flight Deck runs Collins Pro Line 21 Advanced avionics. These include a synthetic vision system that shows terrain and obstacles in three dimensions, a new flight management computer and the MultiScan weather radar. A head-up display is available as an option.

Engines: The two GE CF34-3B engines run in the MTO version with about 41 kN of thrust each. Compared with the 605, they deliver about five percent more power on takeoff. That shortens the takeoff distance and increases payload at demanding airports, for example at high elevation or in hot weather.

The most important visual dividing line is therefore not between the 605 and 650, but between the 604 and 605: the 605 brought the larger cabin windows and a modified tail cone. If you see the small windows of the earlier generation, you can rule out the 650.

The three features that are enough to identify it

Many business jets have a T-tail and rear-mounted engines. Three checks will still quickly narrow down the Challenger 650.

How to find an aircraft specifically by its registration or hex code is explained in the article How to track an aircraft by registration. What lies behind four-character codes like CL60 is covered in ICAO type designators explained.

Lookalikes: Challenger 350, Gulfstream and Falcon

In business aviation traffic, several jets of similar size often stand side by side. The finder helps you narrow it down.

The Challenger 300/350 and the Challenger 3500 are almost as long, but slimmer and fitted with outward-angled winglets. The Gulfstream G450 gives itself away with its large oval windows and longer fuselage. The Dassault Falcon 2000 is also a twinjet with rear engines, but its horizontal stabilizer doesn’t sit at the very top of the fin. The Embraer Praetor 600 and the Cessna Citation Longitude play in a similar league; type code and registration help fastest here. Bigger and with a much longer fuselage is the Global 6000/6500, Bombardier’s long-range line. An overview of the features of all the big families is in the guide How to tell Gulfstream, Global, Falcon, Citation and Challenger apart.

Who flies the Challenger 650

The Challenger 650 is in demand mainly with companies, private owners and fractional providers. According to available figures, NetJets operates more than 50 and is thus the most important single customer. Charter operators also use the type on longer routes because of its wide cabin.

A special case is the special-mission platform. The wide fuselage and solid range make the 650 interesting for agencies and armed forces:

• The Swiss air rescue service Rega replaced its Challenger 604s from 2018 with three Challenger 650 ambulance jets. The cabin is set up like an intensive care unit, and up to four patients can be transported lying down at the same time, two of them in intensive care.
• The US Army has operated two Challenger 650s as the ARTEMIS reconnaissance platform since 2020.
• The Finnish Border Guard ordered two Challenger 650s in 2024 for border and maritime surveillance.
• The United Arab Emirates Air Force ordered one in February 2019.

For you, that means: the ordinary white corporate 650 is not a rare catch. It gets exciting with rescue and agency aircraft, eye-catching paint schemes or unusual countries of registration. Why many business jets are registered in places like Malta or the Isle of Man is explained in the article Offshore registrations and leasing. You can gauge whether your sighting is something special with How rare is my sighting?.

Where to find the Challenger 650

Business jets fly without a published schedule, and some operators have their data filtered in trackers. But the Challenger 600 family is widespread, so you have good chances at airports with business travel. The 650 itself is only part of the CL60 movements; many aircraft are older 604s and 605s.

Switzerland: Geneva Airport is one of Europe’s most important business jet airports, driven by international organizations, banks and, in winter, ski tourism. Tips for the spots there are collected in the plane spotting guide for Geneva. At Zurich Airport, Rega has its jet base, and the red-and-white ambulance jets take off and land there in regular traffic. In January the World Economic Forum in Davos brings a spike in business jets.

Austria and Germany: At Vienna Airport, congresses and international meetings regularly bring large-cabin jets. In Salzburg, the festival and the winter season are the high points, in Munich and Frankfurt trade fairs and large events.

European hotspots: In summer, Nice is a magnet for private jets, and Paris-Le Bourget is a pure business airport with a high share of large-cabin jets all year.

Location	Chance of a hit	Why
Geneva	high	Heavy business jet traffic year-round
Zurich	medium to high	Rega base, business traffic, peaks around the WEF
Paris-Le Bourget	high	Pure business airport
Nice (summer)	high	Côte d’Azur, lots of private travelers
Vienna, Salzburg, Munich	medium	Congresses, trade fairs, season
Small regional airports	low	Individual, often unannounced arrivals

Spotting tips for Geneva, Zurich, Vienna and Salzburg

In Geneva, the observation deck is the obvious starting point; because the airport has only one large runway, every jet passes the same spot. In Zurich, the Butzenbüel offers a good view of the runway system, and with a bit of luck of a Rega jet on approach. In Vienna, the spotters’ hill is a good choice, in Salzburg the observation deck, from where you can get business jets close up in your lens while they taxi. In Munich, the visitors’ hill is the classic.

Photo tips for the Challenger 650

At just under 21 meters, the 650 is shorter than an A320, but its tall fuselage makes it a rewarding subject.

The shape of the wingtips helps tell it from the 350; which designs exist is shown in How to recognize winglets, sharklets and raked wingtips. You work out when the light suits your spot with the sun position planner – how that works is explained in Planning sun position for your photo spot.

Common mix-ups and how to rule them out

Conclusion

The Challenger 650 is the newest and best-equipped version of a family that has been a fixture on Europe’s business aviation aprons for decades. A wide fuselage, T-tail and the type code CL60 show you the way into the family. The last step – 650 rather than 605 – only the registration can take off your hands. That is exactly what makes the type a nice collecting project: if you keep your CL60 sightings tidy by registration, you quickly see how many real 650s are among them, and with the Rega jets in Zurich there is one you can plan for deliberately.
