Can someone teach me how to use the IPad thing on aircraft?

So, I was just about beginning my flight from Beale Airport to St Maarten. Obviously I’ve seen the IPad thing before, but when I type in the airport code (ICAO code) it doesn’t show anything. Can someone who knows how to use it teach me how to make the airport show?

First of all the ICAO of saint marteen is TNCM assuming you want the landing distance there is a show landing in the image so tap that and you'll get landing data

And if your talking about wanting the map of the airport it is not implemented

The thing is, when I tap on the airport after I put the code in, nothing shows up.

Are you able to send me a video so I can see? I can't tell through an image

Are you able to send videos on mobile?

That is the EFB or electronic flight bag. To search for an airport you first open the search menu by pressing the button next to the ARPT label and then type in the identifier. Then press the search ident button to see the results. From there tap on the airport to select it.

Ok, I will try to see if this works.

I have tried this, and the same thing happens. I searched “TNCM” (ICAO code for St Maarten) and searched ident, and when I tap it, it just goes away.
