- [SDK: API Documentation](https://fpassistant.com/sdk-api-documentation/) - As a developer you always need to read the documentation to assist you in your work or get the AI model to learn from. For our aviation SDK, we have a sub domain that hosts all the required information and documentation covering all the API’s and handy development notes. This is effectively a website and
- [SDK: TERPS Geodetic Calcs](https://fpassistant.com/sdk-terps-geodetic-calcs/) - 𝐓𝐄𝐑𝐏𝐒 𝐒𝐭𝐚𝐧𝐝𝐚𝐫𝐝 𝐅𝐨𝐫𝐦𝐮𝐥𝐚𝐬 𝐟𝐨𝐫 𝐆𝐞𝐨𝐝𝐞𝐭𝐢𝐜 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐢𝐨𝐧𝐬 (8260.58) - The following FAA standard formulas with test cases passing have recently been implemented to our Aviation SDK: WGS84CrsIntersect – Computes the coordinates where two geodesic curves intersect WGS84Destination – Computes destination point based on course and a static point WGS84PtIsOnGeodesic – Algorithm determines if a point lies on and within
- [SDK: ICAO OLS Framework](https://fpassistant.com/sdk-icao-ols-framework/) - Most of you are aware that ICAO has a working group looking at improvements to the Aerodrome Surfaces criteria with the Annex 14 document. From November 2030, there will be a new criteria for this and it currently known at the ICAO Obstacle Limitation Surfaces (OLS) Framework. This framework divides the new aerodrome surfaces into
- [SDK: METAR and TAF Parser](https://fpassistant.com/sdk-metar-and-taf-parser/) - The development team are pleased to announce that work has started on a tool to parser a METAR or TAF message. The Parse method is called and this will decode the message to create a report object which contains the expanded data. Some data can be accessed as defined in the message and also available
- [SDK: Aviation .NET Objects](https://fpassistant.com/sdk-aviation-objects/) - To assist in your software development, the SDK comes with a comprehensive set of .NET objects covering Classes and Struct's that have been designed to make working with aviation data and calculations an easier process. Where possible the aviation data has can be used between each objects as data types. Having a specific aviation data
- [SDK: Graticule](https://fpassistant.com/sdk-graticule/) - Currently under development is an API to construct a graticule, this is primarily for our CAD customers but we thought that this might be useful for others to. The options are passed as parameters to the constructor and then a call to create the graticule will return a collection of GeoMapElement's. You can then decide
- [SDK Geographical Coordinates](https://fpassistant.com/sdk-geographical-coordinates/) - This is a large part in the SDK which covers many different aspects including coordinate conversions between different map projects, ability to create simply graphical types (Lines, Polygon, etc) and then display on the graphics system of your choice. Specific features in the SDK do create a collection of these geo types for you to
- [SDK: Aviation Data Import](https://fpassistant.com/sdk-aviation-data-import/) - Introduction... We have just started working on a new section for the FPAssistant SDK and that it to import aviation data from many different sources. Over the years we have seen so many different data formats and our customers have had to write their own import routines. Now, in recent years some formats are becoming
- [FAS Data Block API](https://fpassistant.com/fas-data-block-api/) - Final Approach Segment (FAS) Data Block consists of a set of parameters toidentify a SBAS APV I or CAT I and to define its associated path. In some regions GBAS is supported and this is also covered. You can find documentation regarding the FAS Data Block in ICAO Document 8168 (Part III - Section 2)

- [SDK: Indicated Air Speed](https://fpassistant.com/sdk-indicated-air-speed/) - To calculate True Air Speed (TAS) we can use the IndicatedAirSpeed object. We can also retrieve the value of the K computed component. To offer flexibility, there are two constructors both require the air speed and an altitude value with a temperature variation optional. The air speed and altitude are objects in their own right.
- [SDK - Release 2025.11.17](https://fpassistant.com/sdk-release-2025-11-17/) - Today, we have released the latest version to NuGet, it can be downloaded directly from here.
