FAA 13 Runway Protection Surfaces (Aviation)

Available with Aviation Airports license.

Available with Aviation Charting license.

Summary

Generates runway protection surfaces based on the FAA Advisory Circular AC 150/5300-13B specification.

Safe and efficient landing and takeoff operations at an airport require that certain areas on and near the airport are clear of objects or restricted to objects with a certain function, composition, or height. These clearing standards and criteria are established to create a safer environment for the aircraft operating on or near the airport.

Usage

• The Input Runway Features parameter value must be z-enabled.

• The Target OIS Features parameter value must be z-enabled.

• This tool generates runway protection surfaces in an existing polygon or multipatch feature class. If a feature class is used for the Target OIS Features parameter value, it must have a vertical spatial reference. It should have Name and Description text attributes, which will be populated in the output features. Suitable Target OIS Features parameter values can be the following features classes from the Airports 18B schema (Airports18B_NAD83_GX.xml): Airspace\ObstructionIdSurface, ObstructionIdSurface_MP, or RunwayProtectArea.

• This tool generates runway protection surfaces based on design matrices defined by the FAA. A design matrix consists of an approach category and approach design group. Use the Approach Category and Approach Design Group parameters to set the design matrix for the surfaces.

  Some design matrices only apply to aircrafts under 12,500 pounds. Use the Aircraft Type parameter to specify the design matrix for an aircraft.

• If the Runway End Features parameter is specified, the corresponding field values in this layer will override the values specified in the Approach Category, Aircraft Design Group, and Approach Guidance parameters. This is useful for providing specific input per runway end. The Airfield\RunwayEnd feature class is suitable input for this parameter with the Approach Category, Approach Guidance, and Design Group fields populated.

• High end of the runway refers to runway direction identifiers 19 through 36. Low end of the runway refers to runway direction identifiers 01 through 18.

• The Airport Elevation parameter has a default value of 0. If you use an elevation value greater than 0, it takes precedence and overrides any existing airport elevation value read from the Input Airport Control Point Feature parameter.

• The Input Airport Control Point Feature parameter can be used to supply x-, y-, and z-geometry for displaced threshold features. If displaced thresholds are included, surfaces will be constructed based on their x-, y-, and z-geometry instead of their corresponding runway feature endpoint.

• To create a .json file for the Custom JSON File parameter value, use the CustomizeOIS.exe file that is part of the ArcGIS Aviation data package available from My Esri.
