    Re: A noon fix inland with an peri-sextant

    Excuse my lack of knowledge, what is a peri  sextant?

    Sorry.  I should have said periscopic sextant.  It fits into a mounting inside the fuselage and can be raised into the slipstream.  There have been many photos on NavList, so to save repeating them, just type ‘periscopic sextant’ into the search box of Google Images, and you’ll see a selection.  DaveP
