To be clear, we're actually talking about two separate things, they both just use an iPad.
You're talking about what's known as an electronic flight bag, which is using a tablet as a replacement for paper maps and charts. This is legal and has been for some time.
What I and Animats are talking about is running an app on a ipad as a "replacement" for equipment or training that is required for safe, legal, operation. NOT legal.
Maybe because the iPad has a more user-friendly interface than most avionics.
Here's the cockpit of the Gripen, Saab's current fighter aircraft.[1] One big screen across the whole panel. No sign of a classic altimeter or compass. There's a HUD as well, so there's a second device for the basic flight instruments.
