In my opinion these radars will detect and show small islands and rock regardless of mode and that they are safe and for awoiding terrain when flying over sea. Of course, as with all equipment, you need to be trained with to use it and I think we can safely assume that this crew was trained.
Earlier days of SAR only had the SAR/Wx-radar to rely on, combined with paper maps/sea carts for close-to-land operations, at least where I come from. In my world the radar picture superseeds moving map if seing ground/osbtacle on the radar( of course you should use all system that adds on SA).
I would absolutely think that the radar could be trusted, and that the radar should have been one of the first slice of the swiss cheese. The EGPWS should be one of the last. Said to see that it did not do the work this time.
Well said AAKEE!
Unfortunately 10 nm scale is not that perfect to detect obstacles within range 1,3-0,6 NM.
