    Re: Kollsman Periscopic Bubble Adjust

    I guess you didn't see my prior post and the attached photos.

    I was at the EAA convention in Oshkosh two weeks ago. I visited the cockpit of a brand new C-130 with eight bladed propellers and had a discussion with the navigator. Celnav is alive and well in our airforce in 2019."

    I posted the photos for the original poster, a former air force navigator since he would recognize the items immediaely. For those who are not familiar with this equipment, the first photo shows the periscopic sextant mount in the overhead, the second is the box containing the Kollsman periscopic sextant strapped to its place and the third is HO 249, the standard computation tables.
