I’ve started flying with my iPad properly mounted on my leg.
Previously I had it loose in the cockpit, usually in the back pocket of passengers seat. Easily accessible, but not always, as I had to stow it in critical portions of the flight.
Finally, I found an inexpensive and really good iPad mount, case or whatever you call it. It’s Otterbox Latch Case.
It allows me to use the iPad either horizontally or vertically ( can sometimes block full movement of controls, just like any large knee-board ).
Has interesting pouch which contains additional straps, and basic iPad cover, but the best thing about it, is that it functions as a “wedge” to raise one side of the iPad to increase visibility.
It’s a solid product and you don’t have to spend hundreds of pounds to have it properly attached. It just works!
