No anti skid. No TRs or TAs. No spoilers. The MTOW went from 4500 lbs to 6000 lbs with no braking system changes. On top of that, they blow tires like Ford Explorers. Being certified under part 23, there are no runway contaminant charts. There's no moving map in this revolutionary airplane; nowhere to enter a flight plan. There are two GPSs on board, but the pilots have no way to interface with them. The airplane is /W. That's right. No RNAV. It's VOR to VOR navigation, or just ask for vectors and use the Garmin 496 that comes with the airplane 'cause it's easier. There's no TCAS. No TAS. No TIS. There's no TAWS. There's a radar in the nose, but it's not plugged in. The windshield heat? Also not plugged in. The boots take about 60 seconds to suck back down, so it's not approved for known ice. Its 'circuit breaker' is collared anyways. The autopilot can hold a heading, hold a pitch, and capture an altitude. No coupled approaches - it can't even track a course. Autothrottle permanently inop. There's a fancy keyboard, but with the lack of a FMS or a usable GPS, it's mostly inop too. Uncommanded trim is a normal occurance. Random fuel gauging issues on all of the ones I've flown. CAS messages come and go with no rhyme or reason. The computer is in control of everything you do - there are two hard circuit breakers on the airplane, everything else is software. There are all sorts of cool ideas incorporated into the design but no software to make any of it work.
FADECs misbehave.
Parts fall off. Lost all electrical power? No way to shut down the engines. Can't change power or even shut off the fuel. The type certificate was issued WAAAAY prematurely and the guys operating them now are test pilots. Thank baby jesus it's not fly by wire or people would be dead already.
On the plus side, it's got a pretty sporty roll rate.
