Obstacle Evaluation / Analysis Feature

With the increasing use of electronic Terrain and Obstacle Data (eTOD) there is requirement for fast and effective evaluation of this form of data against 3D surfaces (facets). The FPAssistant SDK will soon offer full support covering the 3 types of obstacles being analysed for intersection on planar and non-planar 3D surfaces. Namespace FpAssistantCore.GeneralAviation.Obstacles There [...]

TAS and Conversion Factor

Question: How can I calculation a True Air Speed and obtain the conversion factor? In the SDK we use the IndicatedAirSpeed struct which has a few different constructors to handle a different temperature variation, the full API documentation can be found here. Two values are required, these are an Airspeed and an Altitude value.  So an example [...]
