Airbubba, something to chew on in the old "what would you do if _____?" ready room discussion.
From the IGARI waypoint, what point could they get to and land within about 15 minutes?
I recall a "rule of thumb" (which I have seen discussed here on PPRuNe regarding in flight fire scenarios) that if you don't get the fire out / aircraft on the ground in about fifteen minutes, the chances of it all ending in tears increases dramatically.
IF fire is what's happening, a location he can get to in 15 minutes strikes mes as the first target for a Captain of that experience level.
Complications include:
It's now a non-moonlit night
Flying a heavy with a substantial fuel load still on board
Few airports open at night.
Crash crew potentially available
Further this thought:
IF fire, and IF ALSO successful fire put out (hooray for the crew!) Captain still wants to land soon, but as fire is no longer burning more time available and thus more landing options.
