Another 3.1 Stair_ Headroom-COACH PLEASE REVIEW-TEST TOMMOR

Postby carpar » Sat Dec 16, 2017 9:57 pm

Hi all,

I tried out another stair version to test headroom rules. I calculated headroom clearance to be 9'2" (8' door + 2" frame + 1' stair/landing depth).
This rationale is correct?

Also:

I doubt this will be encountered in the vignettes but:
What is the max ramp run? (30" rise)?
What is the max stair flight between landings? (12' measured vertically)?

And is more than one intermediate landing allowed (if in a jam)?

Thank you!!!

Yes, but I don't see that condition here.

I doubt this will be encountered in the vignettes but:
What is the max ramp run? (30" rise)?

If the exam code doesn't say anything about that it doesn't exist.

Of course.
