Sorry if this has been posted here elsewhere, but with all the time I spent searching the web last weekend, I've used up my monthly wasting valuable time on the web allowance. Hopefully someone can point me in the right direction.
I have heard different discussions on this subject numerous times over the years but am looking for something official in writing. This should be easy and maybe it is.
One does not have to look too far to find required runway markings for paved runways. My FAR/AIM manual is full of it along with thousands of other places in the web. Everything official I found was on paved runways.
My quest is for standards and/or requirements for grass runways. I'm interested both public use or private strips. I do not recall where, but I found a document stating markings for turf runways is the same as paved. I should have saved a link to it, but I was too far beyond to go back.
Thank you in advance for any input.
