EC135 stretcher limits  

I remember seeing one of the earlier Ferno's that calls out the 400, ours is the 28-A1.

28-A1 | Ferno

The site shows it as 700 which is what the placard on the thing says.  Very interesting on the number of people and the limits.  I'm hoping someone can point to a piece of paper for the 350 limit or it might just be a company back saving rule.  We have our girth limits for actually fitting through the tunnel but those are casual numbers, not written in stone.  I'm just doing my best to answer the crews question and now my own about where that 350 came from.
