AIP data refreshing and assigning of Obstacle Limitation Surfaces

Completely updating, assessing and providing the Aeronautical Information Publication datas to air navigation services. Precise editing of the Aerodrome Obstacle Chart (AOC). As a result of continuous control and updating, the AIP extract data provides information on the state of the current conditions,  including the accuracy, resolution and integrity requirements. All this in accordance with ICAO 8126 AIS Manual, ICAO Doc 9157, ICAO Doc 9674, any related documents and the Regulation (EU) 73/2010 (ADQ).

Categorization of terrain features by ICAO

The surveyed terrain features are sorted according to the set of conditions defined by international and domestic legislations. Terrains – that have reached or exceeded the defined surface of the area (collection surfaces) or the relative altitude criterion are reached – will set on Flying Obstacle databases.

Electronic Terrain- and Obstacle Databases

Erenfield’s software suite in compliance with the relevant regulations (including ICAO Annex 15, etc.), will make it possible to create a obstacle database and edit aeronautical charts.

Survey data package types

The eTOD survey provides different types of data packages to the Airport operator:

  • Assigned Obstacle Limitation Surfaces (OLS)
  • Digital Terrain Model (DTM)
  • Digital Surface Model (DSM)
  • AIP refreshing data package
  • Ortophoto and raster files from the specified areas

During data collection, raw data are integrated into an AIXM data model.
