## Introduction
The Aeronautical Data APIs, part of the [Laminar Data Hub](/apis/laminar-data-hub/overview) provide information on airspaces and microlights. 

Cirium is transitioning [Aeronautical V1 APIs](/apis/laminar-data-hub/aeronautical-v1) to v2 APIs and will eventually retire v1. In the meantime, please see [Aeronautical V1 APIs](/apis/laminar-data-hub/aeronautical-v1) for more Aeronautical APIs. 

## Licensing
The Aeronautical Data APIs currently require a contract to use. 

## Schemas

Aeronautical Data V2

Retrieves full details for airspaces within the provided ISO 3166 Country Code in GeoJSON.

The ISO country code for an airspace e.g. FRA (Case sensitive)

country.iso

user_key

The request sent was not understood by the system

The request sent was not authorized by the system. e.g. The user_key does not have permission to request data for the given country code.

The request sent could not be authenticated by the system

Retrieves full details for microlight aerodromes within the provided ISO 3166 Country Code in GeoJSON.
 
Microlight aerodromes are small, often grass runway, aerodromes that are used mostly for hobbyist flights. They may not appear in our other aerodrome APIs as they are often
 too minor to appear in many official databases.
 
 *Important:*
 - This API is *NOT* AIRAC cycle based and may update on any day.
 - Currently only France (FRA) is supported. If any other country code is requested
 you will receive a 422 error response.
 - Use of data provided by this API is subject to clause 1.6 of the Laminar Data End User License Agreement.</p>


The ISO country code to filter aerodromes by, e.g. FRA (Case sensitive)

The request sent could not be processed by the system

Microlight Aerodromes By ISO 3166 Country Code

fir.icao

Retrieves a list of airspaces for a FIR, depending on response content type chosen the format will be
different:

- application/geo+json will produce a GeoJSON formatted response
