    Re: Planning a fix with >45 degrees intersection inLOPs

    In the Vulcan, we were looking for a close to 90 cut.  In pre PC and smart phone days, we just used the sky diagrams in the Air Almanac.  They always worked fine for us.  On the diagrams pages, you just got star numbers, you had to find the names elsewhere, but you did get stellar magnitude, which was quite important.  It was no good having a perfect cut if you were going to have difficulty seeing the star.  I believe the UK Air Almanac is a much thinner volume these days, but the US Air Almanac is still the same.  You can download it free at http://aa.usno.navy.mil/publications/reports/aira16_all.pdf .  (downloadable in about 30 seconds)  You need the pages starting at A24 though to A121.  They’re about 9/10 of the way through. 

    With a PC it's easy. With'Navigator'  http://www.tecepe.com.br/nav/ , which I use occasionally although there must be many other programmes, you can generate a sky diagram for any place any time almost instantly.  DaveP
