So what are you proposing FJJP? Mandatory asymmetric commital heights? Let's say we make it 600 ft. That sounds like it has a nice additional safety margin included.
So I'm approaching my destination which is giving 2000m vis, BKN004 in my light twin. Not too challenging for a symmetric ILS approach. I'm solo, and at the end of my flight so I'm light. An engine starts to surge, to the extent that I feel the best strategy is to shut it down. Now what?
Options:
1) Fly the approach, knowing that by 600 ft I probably won't be visual so I'll have to do an asymmetric go around?
2) Fly to my alternate with a non-precision approach, reporting 3000m BKN007 but sufficiently far away that I need to fly for 30 mins on a single engine and I consume all my alternate fuel getting there.
3) Something else?
Your call.
