python-airac

Regular, planned Aeronautical Information Publications (AIP) as defined by the International Civil Aviation Organization (ICAO) are published and become effective at fixed dates.

AIRAC cycle definition as published in the ICAO Aeronautical Information Services Manual (DOC 8126; AN/872; 6th Edition; 2003). Test cases validate documented dates from 2003 until 2022. They also assert that the rare cases of a 14th cycle, e. g. in the years 2020 and 2043 are correctly handled.

This project provides a Python library to deal with AIRAC cycle dates.

This project is not maintained by ICAO. Please use this project at your own risk.

Installation

python-airac is not currently a Python registered package.

Currently only developer version is available. It can be installed by running commandline:

$ pip install git+https://github.com/scls19fr/python-airac

Usage

Airac object

Get current AIRAC cycle

In [1]: from airac import Airac

In [2]: airac = Airac()

In [3]: airac
Out[3]: <Airac 2101 2021-01-28>

Get first AIRAC cycle of a given year

In [4]: Airac.from_year(2021)
Out[4]: <Airac 2101 2021-01-28>

Get properties of an AIRAC cycle

In [5]: airac.date
Out[5]: datetime.date(2021, 1, 28)

In [6]: airac.ident
Out[6]: 2101

In [7]: airac.year
Out[7]: 2021

Iterating over AIRAC cycle

In [8]: airac = Airac.from_year(2021)

In [9]: airac.next()
Out[9]: <Airac 2102 2021-02-25>

In [10]: airac.move(12)
Out[10]: <Airac 2113 2021-12-30>

In [11]: airac.previous()
Out[11]: <Airac 2014 2020-12-31>

Showing all cycle dates for a given year

In [12]: g = (Airac(d) for d in airac_cycle_dates(2021))

In [13]: list(g)
Out[13]:
[<Airac 2101 2021-01-28>,
 <Airac 2102 2021-02-25>,
 <Airac 2103 2021-03-25>,
 <Airac 2104 2021-04-22>,
 <Airac 2105 2021-05-20>,
 <Airac 2106 2021-06-17>,
 <Airac 2107 2021-07-15>,
 <Airac 2108 2021-08-12>,
 <Airac 2109 2021-09-09>,
 <Airac 2110 2021-10-07>,
 <Airac 2111 2021-11-04>,
 <Airac 2112 2021-12-02>,
 <Airac 2113 2021-12-30>]

Showing all cycle dates between 2 dates

In [14]: 

Parsing an AIRAC ident string

In [15]: Airac.from_ident("1913")
Out[15]: <Airac 1913 2019-12-05>
