AIUI, the iPad Air does not support full dual screen multitasking - it just plays at it.
I believe the Air 2 does, and the iPad Pro's definitely do. I have a Pro 12.9" and have dispensed with kneeboards and charts, and now run SkyDemon on the left hand side of the screen, and an note pad app called Goodnotes on the right hand side, in which I have created a simplistic plog template. Using an Apple Pencil, I can scribble on the plog with SD running perfectly on the left.
When I get home this weekend I'll be trying it out with a browser on the right hand side, displaying PAW Radar!
