P3D v4 Get the current airport ?

Hello all
I'm working on a project with simconnect and i need to get the user current airport, where is the user aircraft parked, just the airport no need for the gate
well i used the simconnect get the nearest observation to get the ICAO, but that seems to work in my weather engine for sure but here i really can't make it works as the project doesn't have relation with the weather so i won't touch the user weather to get what i want

well hope you help me, thnx in advance :)
