"Both pilots told investigators that they had previously experienced failure of primary flight instruments at low level and at night in different aircraft (without synthetic vision systems). They had been able to disregard the erroneous or failed instruments and reference the standby instruments to maintain control of the aircraft and situational awareness. However, the pilots told the ATSB that the prominence of the synthetic vision display was so prominent that it was difficult to ignore the erroneous information and locate valid information. Additionally, the pilot flying reported feeling a level of motion sickness, probably associated with the combined effects of the prominent synthetic vision display and conflicting vestibular sensory information."
I am surprised there isn't a flag immediately when incoming data from multiple sources has a conflict. GPS says you are ascending, radio altimeter with terrain data says you are descending - one of them has to be wrong.
