<!-- badges: end -->

The `airac` package helps with determining the ICAO's AIRAC ID or the relevant
date intervals as used internationally and by the data services of the
European Network Manager.

AIRAC stands for Aeronautical Information Regulation and Control and it indicates
the period used to publish and disseminate changes to [aeronautical data][aip].

[aip]: <https://en.wikipedia.org/wiki/Aeronautical_Information_Publication> "Aeronautical Information Publication"

# How to build the pakgdown from behind proxied Internet
library(withr)
library(pkgdown)

with_options(list(pkgdown.internet = FALSE),
             build_site())
```

Note that the pkgdown website is generated automatically via GitHub Actions and published on a separate branch.
it will then be served by GitHub Pages as per repo configuration.
