If you have Apple TV, I believe you can use that to get your iPad to the big screen.
On one hand, I do agree that actually flying in a good location is best for learning to fly your phantom. Early on and regardless of the software you have at hand on screen, you tend to focus almost fully on just the bird and the sticks, and that's a good thing. The hands and the eyes and the brain need to make sense of what's going on and nothing does it better than watching your bird respond in flight to what you're doing with the sticks. However, the dji simulator is an excellent tool as well. I'll go so far as to say that if you've never flown a drone, use the dji simulator first for a bit. You can safely fly the drone and learn stick control. Even more importantly, you learn the what, where and why's of all the app information too, which is is actually critical information for safer flight. There's a lot to absorb as far as the app is concerned. Learn it all in the simulator. Be comfortable with it. Then on a nice calm day, go and fly. You'll find that actually flying is different than having worked in the simulator, but you'll also benefit a lot and feel that much more comfortable from having gotten very familiar with the app, the telemetry, and all that information has to offer. Enjoy!
