    OK. Different animal. I remember the late John Luykx – who was an acknowledged expert on aircraft sextants -- giving a most animated and entertaining description of the operation of one of those models. I have never seen one first-hand.

     

    It is amazing to see the variety of systems that were developed to produce a reliable artificial horizon. In the final analysis, it appears to me that the simple spirit level, or bubble turned out to be the most accurate and reliable. Of course I am not including in this lot, the sophisticated sextants used on the Apollo missions.

    Yes, I think they were but also on surface vessls I understand.

    They are spun up with an air pump rather like a bicyle pump.

    I have the operation booklet in German. Apparently they were spun up then carried up the conning tower to take a sight. All a bit hairy it sounds.

    Mine was badly damaged but I got it working enough to see that it would work, accuracy similar to the bubble version.

    Paul.
