The Embraer Legacy 600 corporate jet is a very popular corporate jet mainly due to its range and size. It can fit up to 16 passengers comfortably (37 in standard aircraft seating) depending on its configuration. It does however require 2 pilots but a flight attendant is of course optional. It is powered by two Rolls Royce AE 3007 turbo fans which gives the aircraft a top speed of 834 kph. The range is actually very good for a jet its size as it can fly from New York to London in one go.
