In actual fact we aviated then communicated our observations to ATC who were happy for us to continue with our slightly longer than published hold, then we continued to navigate using a mode enabling me to concentrate on the big picture - such as how much fuel we had! It was deemed by myself as the Commander the safer option at that time owing to several other factors!
I agree using Lnav holding above Msa under radar will reduce workload,however you did enter a non standard hold albeit agreed upon by ATC and then started to work out how much holding fuel you had...
How about a brief before descent concerning holding fuel?possible alternates..or was it not deemed important by then?
So you were both concentrating on the same things? How about one flies and the other(captain) makes those last minute decisions?
I dont want to seem too harsh but it seems some just didnt work out well on that flight...dont you think?
