Terminal Silhouettes: FRA




Switching Flight Historian to ICAO Regions

Early on during the development of Flight Historian, I realized that I’d have to do some filtering of my maps by region. Most of my travel is within the United States, so a world map of all of my flights left the United States as an unreadable mess of lines. Thus, I gave Flight Historian the ability to toggle between world maps (all flights) and CONUS maps (flights within the CONtiguous United States – that is, the United States except for Alaska, Hawaii, and territories).

Because of peculiarities with how the Great Circle Mapper generates maps, showing region maps wasn’t as simple as setting a map center and zoom level. Instead, I had to know which airports were inside the CONUS and which ones were outside. The easiest solution was to add an is_conus attribute to my Airports table, which would be set to true for CONUS airports and false for OCONUS (Outside CONUS) airports. Once I had that, I could set the world map to use every airport, and the CONUS map to show only airports where is_conus was true.

This worked well enough when I was only showing two regions (world and CONUS). But as I traveled, I realized I was going to want to zoom in on other regions (for example, Europe) as well, which meant that I’d have to have some way match airports to other regions.

Airport #78/100: Peoria (PIA)

General Wayne A. Downing Peoria International Airport
Peoria, Illinois, United States
First visit: 3 August 2017

I didn’t originally plan on visiting PIA. I’d been flying between Tulsa and Chicago O’Hare when thunderstorms forced us to divert.

While this is not the first weather diversion I’ve had, I only count diversions as an airport visit if passengers are allowed to deplane. (If I’ve never been inside an airport, it’s hard for me to say I’ve visited it!) In this case, though, we had to wait several hours, so they pulled up a jetbridge and I was able to visit the airport terminal.
