Thanks for the Feedback This project is building of a new version of PANS-OPS software. The testing of this software has been completed. Thank you for providing your feedback of the previous version. We really appreciate several inputs were made from the ICAO IFPP and the IFPDAVA members. We will offer this software at no cost to ICAO if needed. Please do not hesitate to contact ICAO IFPP Japan member or advisor.

Small Gift This is a small gift to all of you who helped us. You can use this to create KML files which can be viewed in 3D on Google Earth. After you select aerodrome name in sample aerodrome information box or fill any actual or fictitious airport runway coordinates into custom aerodrome setting box like OAS software, you can get the KML file by pressing the KML button on the bottom left. We would be happy if you could use this software for research or educational purposes.
