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

The optimum tool for obstacle limitation analysis

Obstacle Surface Planner™+ offers functions that provide for fast and reliable obstacle clearance organization, analysis and in-depth studies based on geographical input. These extended capabilities even allow users to assess user-defined obstacle and terrain clearances. 


Obstacle Surface Planner+ Software Package

Ensure maximum safety in all aircraft operations

Obstacle Surface Planner+ ensures compliance with International Civil Aviation Organization (ICAO) and Federal Aviation Administration (FAA) regulations, which in turn helps to ensure maximum safety in all aircraft operations.


The application effortlessly creates the various Obstacle Limitation/ Clearance Surfaces through a series of built-in algorithms and analyzes the impact on these surfaces of any obstacle or terrain data that has been defined or imported. The surfaces can be depicted based on either ICAO or FAA (several optional National Guideline packages are also available) standards in a 2D or 3D Autodesk® AutoCAD® environment, to allow for easy integration into an Airport Layout Plan, an airport’s obstacle map, or other types of software including GIS applications.




Feature Spotlight


Ensure clarity, efficiency and cost savings

Obstacle Surface Planner™’s 3D capabilities provide an unparalleled level of clarity whereby obstacle penetrations are shown in a clear and presentable format. The program can automatically generate the Obstacle Limitation Surfaces you need in just a matter of seconds, efficiency including those timely-to-generate contour elevation interval lines. All this means a reduction in CAD drawing time and decreased plan generation costs.
