iPad controller requirements for Mavic - WiFi or WiFi + Cellular?

[Shoei39]

When using an iPad with your Mavic controller, is WiFi + cellular required or will WiFi work just as well? Thanks for any advice you can provide on this issue.

Neither is needed. I fly in airplane mode so no WiFi or cellular is being used.

Does your return to home and other gps related features work flying in airplane mode?
