On 31 October 2016, Obstacle Surface Planner was succeeded by SkySAFE™.


Guaranteeing safe operations through the protection of departure and approach paths is of critical importance to every airport. Transoft Solutions’ SkySAFE™, the successor to Obstacle Surface Planner™, assists with this challenge. The AutoCAD®-based software allows planners to easily control existing or potential obstacles in an airport’s surrounding environment against regulatory guidelines which in turn, helps to ensure maximum safety in all aircraft operations

Create Obstacle Limitation Surfaces in 2D or 3D

Through a series of built-in algorithms, Obstacle Surface Planner users are able to effortlessly create and graphically present the various Obstacle Limitation / Clearance Surfaces. Surfaces can be depicted based on either FAA or ICAO standards, in a complete 2D or 3D AutoCAD environment, allowing for easy integration into an Airport Layout Plan, an airport’s obstacle map, or other types of software including GIS applications.


Obstacle Surface Planner features include the following, amongst others:


Runway creation

  • Create as many runway environments as necessary based on FAA Airplane Design Group or ICAO Code Letter, including single or multiple runway scenarios, parallel runways or intersecting runways

  • Create approach and departure scenarios based on the types of approaches and aircraft approach categories

Building & Object creation

  • Create individual 3D obstacles using the intuitive ‘Create buildings/objects’ command

Obstacle Limitation / Clearance Surfaces

  • Create obstacle surfaces and obstacle free zones including as defined in ICAO Annex 14 and FAA AC 150/5300-13/18B and Part 77

  • Generate contour lines for at intervals specified by the user

  • Visually analyse the impact of user-defined obstacles in 2D and/or 3D
  • Review detailed numerical information such as the object height at surface and/or amount of penetration
  • Export results to Excel 

Administrative controls

  • Change layers and colors to create a CAD-based graphical depiction

  • View surfaces and zones in 2D and 3D using standard orbiting tools
