The airac package

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.

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

with_options(list(pkgdown.internet = FALSE),
