Just wondering ... maps ...
Descending (fast) from 21,000ft through 19,000ft under highly stressful conditions ... Maps give Trans Level FL 190 and Trans Alt 18,000ft ... what altitude setting were they on ... (if not reported, then you would of course need CVR and FDR to answer that one)...
Comparing IAC maps with Jeppesen maps ref indication of ground contours/altitudes. IIRC in for example the Guam case there were comments on the contours/alts, the impact area not being properly indicated. In this case the Jeppesen appears to be superior to the IAC map. The Jeppesen contours say 8,000ft by the way.
There is a nasty isolated hump along the approach path around D5 IMDE. On the IAC map it says 8040ft (but you might overlook that). On the Jeppesen it says 8157ft (indicated more clearly, but i had to check if it said 6157 or 8157 because of the contour line).
So pilots who had been there before and pilots who looked at their maps, forgetting the 12,600/13,100 ft MSA, in an emergency would probably make sure they would stay well above 8,200ft.
Which triggers the question who was PF. The FO being reported talking to ATC, would suggest the Capt to be PF. How familiar was the PF with this specific airport. What kind of terrain map would he have had in mind.
IIRC the Lamia flight at some stage reported being 'visual with ground'. They were flying in the dark. The most likely visual might have been La Ceja. If you look at videos from the approach and aerial pictures, then La Ceja has quite typical contours. Wonder if having grating type contours of towns on the maps would be beneficial in this specific area.
