21 Take Off and Landing Performance Assessment (TALPA)

The Takeoff and Landing Performance Assessment (TALPA) initiative reduces the risk of runway overruns by providing airport operators with a method to accurately and consistently determine runway conditions when a paved runway is not dry. Airports use TALPA procedures to conduct runway assessments and to report those conditions to aircraft.

21.1 Latest for an Airport

Request the latest TALPA for an airport and runway. See tables below for supported airport (ICAO code) and associated runways.

GET /aviation/observations/talpa/airport/{ICAODesignator}/runway/{runwayDesignator}/latest

21.1.1 API Call:

GET /aviation/observations/talpa/airport/{ICAODesignator}/runway/{runwayDesignator}/latest

21.1.2 Path Parameters:

Path Parameter	Example	Description
ICAODesignator	NZWN	A supported ICAO airport code (upper case). See table below for valid codes. This parameter is Mandatory.
runwayDesignator	34	The runway heading as defined by official publications. See table below for valid codes. This parameter is Mandatory.

21.1.3 Example:

This example would return the latest TALPA for Wellington Airport for Runway 34.

GET /aviation/observations/talpa/airport/NZWN/runway/34/latest

        }
    ]
}

21.2 Last n minutes or hours for an Airport

Request the last n hours or minutes of TALPA data for an airport and runway. See tables below for supported airport (ICAO code) and associated runways.

21.2.1 API Call:

GET /aviation/observations/talpa/airport/{ICAODesignator}/runway/{runwayDesignator}/last/{n}/{timeUnits}

21.2.2 Path Parameters:

Path Parameter	Example	Description
ICAODesignator	NZWN	A supported ICAO airport code (upper case). See table below for valid codes. This parameter is Mandatory.
runwayDesignator	34	The runway heading as defined by official publications. See table below for valid codes. This parameter is Mandatory.
n	10	The duration in time units to return the data for. Valid values: up to 6 hours or 360 minutes. This parameter is Mandatory.
timeUnits	minutes	The time unit for the duration parameter (n). Valid values: hours or minutes (lower case). This parameter is Mandatory.

21.2.3 Example:

This example would return the TALPA’s for the last 10 minutes for Wellington Airport runway 16.

GET /aviation/observations/talpa/airport/NZWN/runway/16/last/10/minutes
