The accident airplane was equipped with an avionics package known as automatic dependent surveillance-broadcast (ADS-B), which is also known as "Capstone." ADS-B technology provides pilots with situational awareness by displaying the airplane's position over terrain, while using GPS technology, coupled with an instrument panel mounted, moving map display. The ADS-B equipment installed in the accident airplane included two Chelton multifunction display (MFD) units. One MFD provides the pilot with a moving map with terrain awareness information, and the other provides primary flight display information. The two MFD units were removed from the wreckage and shipped, to the NTSB vehicle recorder laboratory, Washington, D.C.
That's a lot of equipment to be flying into a cliff, even in marginal VFR/IMC
