More about final CENIPA/NTSB report:
"Cenipa investigators also suggested more rigorous requirements (inspection) of foreigner pilots that operate in the country, requiring needed familiarity with Brazilian air traffic system. In this case, concluded that Legacy’s pilot-in-command didn’t have complete familiarity with glass cockpit technology, by which instructions of flight and operation of aircraft are virtually displayed in cockpit windshield. This partially explain the not intervention in the transponder, although alerts showed that it was off. One recommendation in this case is to reinforce the training for this virtual environment."
CDN_ATC,
Do you know how far is Manaus from Brasilia and how intense is the traffic in this airway? It's equal to crossing all Europe on wrong level. There is a chance of 100% to face another aircraft.
