EGPWS is not the panacea you would imagine it to be and can never be trusted as a primary navigation aid. The Regulator makes that clear as does the manufacturer.
The WX Radar, If used reasonably competently should show a clear coastline. Islands, ships and boats. It's hard to accept that this crew, doing such a procedure, at such heights AMSL, would not have the Radar trimmed for optimum performance. At the heights implied large ships become a hazard. This was their bread and butter day job after all.
It's as hard to accept they navigated to the wrong waypoint.
While there is always potential for human error, In this case there were multiple layers of "humans" experienced and authorotive enough to reduce the chances of an error exponentially.
It is for these reasons that Soggy Boxers is getting irritated because in the end, the only real answers may come from the wreckage, FDR and CVR data. Without this information, nothing of this incident makes any sense when the experience and skills of that crew are considered.
BER nooly. Hope that explains Soggies frustration.
Childlike but also a good question? Which is it? So a downward radar tilt while flying at 220 ft would have no problem detecting something say 2 km ahead?
I never said EGPWS was a panacea or their primary means of navigation, quite the opposite in fact.
There is a way to answer questions, which the vast majority of people have done in a civil way. There is just one senior member that seems to have a chip on his shoulder, as also evidenced in some of his replies on other threads too.
