VFR Navigation Log

Online Javascript based VFR Navigation Log.

This falls somewhere between fully manual calculations using a E6B flight computer (aka whiz wheel) and using fully automated EFB (Electronic Flight Bag) app based navigation. It gives you the pleasure and control of following a more traditional navigational method but once you’ve gotten the hang of it, this NavLog helps with the manual calculations using interpolation, and the E6B, etc.

Fill out the necessary data, press Compute to calculate computed fields. You can print out the page in Landscape mode and use it as a navigation log enroute.

You can have up to 6 rows of navigation routes and fit it all in one page.

This navigation log remembers your entered values using the local storage of your computer (meaning your data is save and nothing is transmitted).

This was a fun little project to implement and I learned a lot, from optimizing the page for printing (page breaks, omitting unnecessary elements and maximizing margins) to using local storage and keeping track of data, not to mention the actual calculations involved in the navigation log. Utilizing html/css to optimize the output and look like a paper navigation log was also a fun exercise.

If you’re interested in the code and perhaps want to add more functionality (like integrating aircraft operational data to further help with the calculations), you can find the source code on GitHub
