    Re: Navigate by Skyline
    From: Bill Ritchie

    I initially used three transits but I thought this fell within Frank's caution of ‘cheating’, so after much head scratching I used the ‘hinted’ single transit from ESB through ‘Luna’ supplemented with a distance derived from pixels and Google lat/longs.

    I chose a third point, the near left corner of 601 Lexington (sloping roof) and measured the pixels from ESB, thus obtaining an angle 2.078°. I used the Google lat/longs to calculate the distance between them  (0.898nm) and an angle from the transit of 48° 49.7’. The Sine of this angle makes the ‘apparent’ distance 0.676nm. Such distance subtends that 2.078° at 18.64nm, which is about 150m S of my three transit position. As with “A flag flying visit”, I attach annotated images. (The right transit uses the near right corner of 601 Lex.)

    Alas my result does not accord with the second clue … the nearest steeple is 4.2nm further due South.

    Like Antoine, I have seen magnificent views of the NY skyline from the air, but by far my best was during the left turn after a night take off from EWR 22R. (B767-236)

    What is NavList?

    NavList is a community devoted to the preservation and practice of celestial navigation and other methods of traditional position-finding. We're a group of navigators, navigation enthusiasts and hobbyists, mathematicians and physicists, and historians interested in all aspects of navigation but primarily those techniques which are non-electronic.

    To post a message, if you are already signed up as a NavList member, start a new discussion or reply to any posted message and use your posting code (this is a simple low-security password assigned when you join). You may also join by posting. Your first on-topic messsage automatically makes you a member, and a posting code will be assigned and emailed to you for future posts.

    Uniquely, the NavList message boards also permit full interaction entirely by email. You can optionally receive individual posts or daily digests by email, and any member can post messages by email (bypassing the web site) by sending to our posting address which is "NavList@NavList.net". This functionality is similar to a traditional Internet mailing list: post by email, read by email, reply by email. Most members will prefer the web interface here for posting and replying to messages.

    NavList is more than an online community... more about that another day.
