A venerable LJ35 will gracefully outperform it any time.
Not if you look for a nice, decent cabin (and a decent cockpit, Proline 21!). That is the strong point of the 400.
All the rest....I donīt now really (havenīt flown the 35), but the numbers donīt look that bad IMO
Long Range Cruise Speed 437
High Speed Cruise Speed 460 (I guess thats faster than the 35 innit?)
Takeoff Length @ MTOGW (SL/ISA st. day) 3906ft (isnīt that better than the 35?)
Landing Distance (4 Pax NBAA IFR Res.) 2960ft
Time to Climb All Engines 14min/FL370
The direct comparison to the 400A is very interesting:
Range (4 Pax NBAA IFR Res.) 2005 50% 1333
Long Range Cruise Speed 437 6% 414
High Speed Cruise Speed (kts) 460 2% 450
Takeoff Length
@ MTOGW (SL/ISA std. day) 3906 - 3906
Landing Distance
(4 Pax NBAA IFR Res.) 2960 - 2960
Single Engine Climb Rate 745 144% 305
Operating Cost per mile $1.91 30% $2.72
Time to Climb All Engines 22/FL430 33% 33/FL430
Stage IV opposed to real noisy (the 400 based at our field is bloody annoyingly loud) and 30% less fuel...that might be appealing to current owners that can`t sell the crappy thing. (and wait til NetJets want to get rid of theirs....the market will be even more flooded then...)
