Thanks for the updated app I downloaded it as soon as it notified me. I'm having an issue using it with the FF777 though. I connect to XP through the app and it displays the FMC but not any display. The buttons on screen can control the aircraft FMC but the display is blank. I've tried auto connect, manually setting IP and I don't have any firewall restrictions. Any ideas?

Whoops, entirely my fault, my apologies!

At some point in time Apple introduced a security scheme for apps that make HTTP connections whereby these have to be specifically allowed and based on SSL by default.

In the making of this new version I had completely forgotten that the 777 (and indeed the 757 and CRJ) use a non-standard scheme to fetch the contents of the CDU screen; they make an HTTP connection to X-Plane on port 18387.

As AirFMC was compiled with the latest Apple SDK, this connection got blocked by this new setting with:

"Transport Security has Blocked a cleartext HTTP"

I've fixed this in a new version 1.3.1 which I just sent to Apple; so as soon as this update is approved you'll have a new version 1.3.1 to download which fixes it. For the time being I removed 1.3 from the App store to avoid breaking it for other people who might not have updated yet.

Again sorry for the problem and thanks for bringing it to my attention.
