API Documentation

Endpoint

export_austria_widget.php

Returns the current daily status of all airspaces available in the Austria Briefing Widget. This includes TRAs from TRA Manager and airspaces evaluated from Air Use Plan and NOTAM data.

https://tra.airspace.at/export_austria_widget.php?importer=abc123

All timestamps in this API are UTC. Local time fields are intentionally omitted. If older internal runtime values exist, they are not exported unless they belong to the current local day.

Access

Importer hash

Use the same importer hash as for the TRA activation exports. Pass it as importer. The sample hash is a placeholder and must be replaced by your assigned six-character hash.

Missing or invalid hash

If public export access is disabled and the hash is missing or inactive, the endpoint returns HTTP 403 with a JSON error object.

Response Object

Unlike the TRA activation export, this endpoint returns one JSON object. The items array contains one current status row per available TRA or Austria Widget airspace.

Field	Type	Meaning
`export`	string	Always austria_widget.
`version`	integer	Schema version. The compact UTC-only API is version 2.
`timezone`	string	Always UTC for this export.
`generated_at`	string	UTC timestamp when the response was generated.
`evaluation_at`	string	UTC timestamp used for status evaluation.
`counts`	object	Total number of rows and counts for TRAs, airspaces and active or scheduled TRAs.
`items`	array	Current daily status rows for every available TRA or airspace.
`summary`	object	Compact current-day source update information. Manual activation details are not included.

Item Fields

Field	Type	Meaning
`id`	string	Stable row identifier, for example tra-2 or an airspace hash.
`type`	string	tra or airspace.
`subject_id`	integer/string	TRA ID for TRAs, airspace designator or bundle ID for airspaces.
`name`	string	Display name used by the Austria Widget.
`group`	string	Tower group for TRAs or category for airspaces.
`status`	string	active, scheduled, inactive or unknown. For TRAs, active means available TRA airspace. For restrictive airspaces, active means closed/restricted.
`source`	string/null	Primary source used for the status: tra, nup, notam or null.
`valid_from` / `valid_to`	string	UTC validity window of the current or relevant daily status.
`updated_at`	string	UTC source update timestamp, if available and relevant.
`sources`	object	Compact source states. Only relevant current-day source data is included; empty unknown source blocks are omitted.
`tra_window`	object	Only for TRAs. Aggregates activation and extension chains into one current from/to window and lists the involved activation IDs.

Status Logic

`active`

For TRAs this means the TRA is active. For AUP/NOTAM airspaces this means the airspace is currently closed or restricted.

`scheduled`

A relevant activation or restriction is scheduled later today.

`inactive`

No active restriction or no active TRA window at the evaluation time.

Airspace status is evaluated from Air Use Plan and NOTAM data. TRA status is evaluated from TRA Manager activations, extensions and deactivations.

Example

Compact UTC-only response

The example shows one TRA with an aggregated extension chain and one restrictive airspace closed by Air Use Plan. The real response contains one row for every available widget item.
