Oke, thank you both for your help. I am making it in VB.net. BUt what do you mean with ApplicationObjects? And for Previous lat and lon I have add this And should I make another dim.... for the CurrentLat and lon with the same value of lat and lon?

Hi, Mm okay thank you. I took a look at the manual and the distance between you and EGLL. That's works for me. But what I want is the position from that you start FS. So in the DIM where you write down the coordinates from egll. It should be the coordinates of your starting location. But I have no idea how to get that.

Hi, As the name says, is there an offset the monitor your distance flown, because I can't find them in the manual.

oww thank you! I don't took a look in the modules map, but thanks anyway!

Oh, Yes but I didn't saw that offset in de ofsett list. The only one that I found was this http://www.fsxcockpit.com/files/FSUIPCOffsets.pdf.

Okay second topic, my first one goes crazy? But back to work. I am trying to make a simple program to see your landing rate. I am working in VB.net. I have now the following code: And And Okay, how it now works: When you are on the ground so landing.value is 1. I can see the vs from that moment in a textbox. But de VS changes a lot and the 1 means you are on the ground, not at touchdown. So what is the best way to make this? Erik
