The folks over at Bombardier have really dropped the ball with this airplane. They could have put the Hawker production line out of business with this aircraft, but they have let so many opprotunities slip away. As for the 45, it was not well planned and has too many problems and a terrible reputation in terms of dispatch rate, Bombardier support, and MX problems. The 60 is a great airplane performance wise, but some of the things the Bombardier designers have come up with makes one scratch their head. Taking the brakes and gear off the 55 and slapping them on the 60 without compensating for the extra weight is just 1 foolish example. On the other hand, they have done some good things like putting the overpowered derated P&Ws on the 60 as well as going with the Collins Pro Line 4. If they do come out with a plane to fill the gap between the 60 and CL300, doing the following would make the folks over at the 800XP-C and Soverign production line sweat.
Must Haves:
trailing link gear
upgrade brakes (Carbon Fiber) enough to lower or eliminate energy limitations as well as a tandem nose wheel configuration
6 foot plug in the fuselage in order to seat 10-12
Brake and Steer by wire (substantial weight savings)
Tiller
EVS
Xenon Landing and Taxi Lights
APU that can be used in flight if needed for Pressurization, ACMs, and DC power with its own battery for start
Huge External baggage
Wing/Slats off of the Global 5K (size adjusted for the 60 Fuselage)
Unleash more power from the P&Ws: be able to T/O out of ASE or EGE at MGTOW/30c with enough fuel to go 1250NM and climb at 1K/Min on 1 engine
Rudder Bias/Boost for SE ops
Increase Mmo (.87-.90)
a true 3000 miles range
Honeywel Primus or Collins proline 21 up front
Auto Throttles would also be nice, but not a must have
price less than 16M
I know this would be a long shot to get all of these things put on a 60, but airplanes would be flying off the production line if these items could be had in an airplane for less than 16M
