Bombardier Global series
The large cabin business jets built by Bombardier are clearly a derivative of the Challenger series and Regional Jet series 100/200. This is especially visible when looking are the front of the fuselage as the cockpit windows and cabin windows are the same. However, the Globals have a different tail and engines with a single exhaust.
To differentiate between the subtypes you have to look at
- the fuselage length
- the number of cabin windows
- the size of the cabin windows
- the top of the vertical stabiliser
Bombardier BD-700-1A10 Global Express, Global Express XRS & Global 6000/6500
The Global Express was the first version of the Global series. The Global Express XRS is an improved Global Express. It is as big as its predecessor and is supposed to have an additional windows on each side: thirteen to the left, fourteen on the right. This results in less space between the cockit windows and the first cabin window. This is especially visibile on the right side, see photos below. However, we are not sure whether older Global Expresses have this extra cabin window as well.
Global 6000 is a new marketing name for the Global Express XRS, to bring it more in line with the rest of the Global line-up. It is not different from the XRS.
The Royal Air Force operates an airborne battlefield and ground surveillance version of the BD-700, designed as Sentinel R1. It is fitted with large bulbs on top of and below the fuselage. The US Air Force has a similarly configured aircraft for battlefield support, known as E-11A.
The Global 6500 is a Global 6000 with Rolls Royce Pearl engines and re-contoured wings. The engine nacelles are the same however, and the wing shape change is probably not visible either. So there is no way of distinguishing the Global 6500 from the Global 6000.
Bombardier BD-700-1A11 Global 5000/5500
The Global 5000 is somewhat shorter than the Global Express. So if you think: “what a short Global Express!”, it is probably a Global 5000. But you probably have to see them side by side to make the difference clearly visible. You can probably not trust the number of windows considering the story for the Global Express XRS.
Like the Global 6500 the Global 5500 is an improved Global 5000 with different engines and re-shaped wings. However, the external differences are not noticable.
Bombardier BD-700-2A12 Global 7500
The Global 7500 is an improved Global 6000 to compete with the Gulfstream G650ER. It is more than three metres longer than the Global 6000, which makes it look like a Regional Jet Series 700. The main difference compared to the CRJ700 is that the engines have a single exhaust, whereas the CRJ700s have a separate fan exhaust. Also the Global 7500 has a different top of the vertical stabiliser. Finally the cabin windows are significantly larger and the winglets are tilted outward.
Bombardier BD-700-2A13 Global 8000
The Global 8000 is to be the business jet with the largest range, designed as 7,900 nautical miles. It is somewhat more that 0.5 m longer than the Global 6500, and thus shorter than the Global 7500. That is probably what will make it as difficult to recognise it as a Global 5500 from a 6500. We will learn when the aircraft flies.
