The paper chart stipulated a minimum altitude of 2500 feet but the computer erroneously gave 2000 feet as the minimum, investigators from the Australian Transport Safety Bureau have revealed in a preliminary report into the June 7 incident.
According to the preliminary report, a cross-checking of the computer and flight-chart data failed to pick up the disparity. The co-pilot at one stage queried the lower altitude but the captain confirmed it by referring to the flight computer.
Don't these guys perform briefings before landing?
Don't they compare their charted approach patterns with the ones given by FMGC?
I can't believe SOP's would allow a pilot to fly below a chartered safety altitude by referring primarily to the computer...
Also, when in doubt (specially when flying low!) one chooses the safer altitude, not the lower. Some call it: common sense.
Others call it also: Professionalism.
