Earlier quoted context omitted.

Each country has slightly different requirements! For the US, here is the FAA rule for it: https://www.ecfr.gov/current/title-14/chapter-I/subchapter-D... A lot of people still use paper (and fill it in after landing each flight), but there are quite a few digital options on the market now. I use one called LogTen, which stores everything in a SQLite file behind the scenes which is what I used to make this.

What happens if you lose it?

You go back to every airline you ever worked for, beg for your flight logs, hope they are willing to provide them, and then over the course of weeks re-enter them into your paper logbook or software. Then you hope that the airline will also be willing to sign-off your logbook.

TL;DR: you're screwed.

That is beautiful. Besides the globe and the cool animations I like the dashboard that shows summary stats. This made me think. Either Frauenhofer or Helmholtz in Germany used to have a site where you could enter your specific flights and it would tell you your overall radiation exposure. This was meant mainly for flight personnel and it was not nearly as beautiful. The accumulated exposure would be a useful addition…

A great idea! The company that I work for does actually provide us with our cumulative dosage data for the month/year/lifetime, but not at such a granular level. Do you know of any statistical way that I could calculate this? I suppose I could work out the great circle routes and the approximate dosage in that airspace at a given time?

For any third parties (I'm getting a wee bit old for these diversions) geophysical survey companies (the ones with crop dusters with stingers on their tails, high wing twin props with stingers and wing tips sensors, etc.) have ongoing globally spread about calibration flights for radiometric (environmental ground radiation) surveys.

The surveys are (usually) 200m spaced grid lines 20km (or so) long flown 80m above ground, the calibration flights are stacked lines from quite high up down to ground level so that the post processing can estimate and subtract cosmic radiation "from above" and how it falls off through the current atmosphere (density, humidity, etc. thinning out current gamma inflow from up high).

Such things, if accessed, would fine tune a radiometric exposure by height model in the same way that using the global magnetic model(s) (there are two main ones) can tune up true north magnetic readings .. it's a fine adjustment that only matters to some.

Some working airport that your cross somewhere in the world likely has a hanger full of geophys survey craft (helicopters and planes) .. might be worth chasing up.

This is awesome and I love it. Thanks for sharing! I'm just wondering what made you wanna be a pilot instead of sticking with a regular software engineering career, especially since you’ve got a degree in that and, of course, your talent here :)
