The speed brakes are located on the rear fuselage rather than the wings and are aerodynamically limited, meaning that at high speed they only deploy a small amount; at low speeds, they deploy fully. The result is that the pilot gets
the same deceleration over the entire speed range, but without the rumble and buffeting that sometimes occurs with wing-mounted brakes.
proactive actions required of the pilot. Dual ice detectors feed information to the de-ice system, which then triggers bleed air on the wing and an electro-impulsive system for the tail. All external lights are LED and are handled automatically. That is, the plane knows what phase of flight it is in, as well as flight conditions, and selects the lights appropriately. For example, once you release the brake, the taxi light comes on. Once you go to takeoff thrust, the landing lights and strobes illuminate. As gear is retracted, the recognition lights come on; at FL180, the recogs and ice lights go off.
Similar to what is found on the much larger Gulfstream G650 or Dassault Falcon 7X, the aircraft is equipped with UTC Aerospace Systems SmartProbes that each have dedicated air data computers to provide airspeed, angle of attack and other flight data. There is no pneumatic tubing or pitot tubes that can potentially fail or get iced up. There is a third backup probe that feeds to a three-in-one Meggitt EFIS standby gauge. As the ultimate backup, this third probe can feed the PFD should the aircraft lose both primary air data probes or if both generators go offline.
