You don't get so much more use of an IR than without it?
You certainly can get lots of out of an IR. A lot of pilots don't like being forced into a small gap below the clouds, but it's perfectly safe to fly above the clouds. You can also fly in very poor visibility, down to just a mile or two, with an IR.
What about big birds when getting engine failure in 200 ft cloud base?
They generally have more than one engine!
