Hi,
First thing there is no Air Player for iPad. To get working what you want you will need an iPad app that turns th3 device into an additional windows monitor. There are a few apps that do this of which Spacedesk is one. Most do it wireless but there are some wired ones out there too.You basically popout the displays from the sim and place one each on an iPad screen. The popular option to do this step is POPM (popout panel manager) because it automated the moving and sizing process and adds also adds touch and sim mouse refocus too.
Air Manager is used to display other instruments/controls and the all essential G1000 bezel controls.
Running iPads will have size limitations. I run dual 24” touch displays for my main instrument panel and plan to also add an overhead and pedestal because even what I currently have is not ideal for some aircraft.
