Embraer 500 Phenom 100, 100E, 100EV & 100EX
The smallest of the Embraer corporate jets is a bit of a crossover between the Cessna CitationJet and the Raytheon Premier I. The Phenom 100 has a quite pointed, streamlined nose, with rather smal cockpit windows but a large, two step dorsal fin. Its straight wings go under the fuselage. They have no winglets, but two wing fences on each side. The Phenom 100 has four cabin windows with a nearly square shape with rounded corners.
There are four versions, which as externally the same. The Phenom 100 is the baseline version. A different spoiler system on the wings is the main characteristic of the Phenom 100E. The Phenom 100EV (for Evolution) has a better performance due to weight savings and a higher thrust setting for the engines. Finally, the Phenom 100EX has a lighter interior, updated avionics and a (fifth) side facing seat as standard. The latter was optional on other previous versions though...
In Brazilian military service the Phenom 100EV is designated as U-100. The Royal Air Force calls them Phenom T1.
Confusion possible with
Embraer 505 Phenom 300
You are very likely to mix-up the Phenom 100 and Phenom 300, as they have a lot in common, externally that is. The main difference it however clear: the Phenom 100 has straight wings, the Phenom 300 swept wings with winglets. Also the Phenom 300 is longer, with five cabin windows, and has a single step dorsal fin.
Cessna CitationJet/Citation CJ series
Another possible confusion is with the Cessna CitationJet and Citation CJ family. The Phenom 100 can especially be distinguished by its more pointed, streamlined nose, smaller cockpit windows and large dorsal fin.
Raytheon 390 Premier I
Like the Phenom 100 the Premier I has a pointed nose, but a larger diameter cabin, three cabin windows different cockpit windows, smaller dorsal fin and swept wings.
Eclipse 500
The shape of the cabin windows and small engines may make you think this is a Phenom 100, but the Eclipse 500 has a tapering fuselage, tip tanks and different cockpit windows.
