Hello

After the current update all planes are in the hangar but not the A310. the installation went well and the plane is in the store but the A310 cannot be selected

hello, not to assume anything.  Did you install the A310 in the content manager.  If you did, I'm not sure what the issue may be.  

 

If on PC, please download the Enhanced version from the marketplace.

Also, does the A310 show up in your content manager?

I installed everything via the contend manager and it is still not visible in the airplane menu

You can´t install anything in the content manager. So let me ask again, can you see the A310 in your Content Manager like so?

PMDG Fenix all are o.k. 
The A310 is Not selectable

Yes

From The contend manager i have installed the enhanced Version

Uninstall the enhanced version, reinstall it and try again please.

If the issue still persists, please report over on the Microsoft forums as we can´t help with installation issues.
