Missed_again
The incident is not nnecessarily due to lack of basic flyin skill. Any normal ILS approach preparation should take into consideration FAF altitude and distance, average ROD and some altitude Vs DME checks and during execution monitoring that it's happening. Even when they were made aware of a threat they didn't seem to have evaluated it so they didn't have any plan to tackle it. That is why they didn't notice the ROD and DME VS height error which they should have monitored even otherwise.They were simply unaware that anything is amiss till the GPWS sounded which is very poor flying. Without that awareness even manually they would have blindly followed the false GS with same result and if they were aware then even with auto pilot on it was possible to prevent it.
