Your iPad's wifi circuity (and cellular circuitry, if it has any) draw some power whether you're connected to a network or not and whether you're actively transferring data or not. Swithcing to Airplane Mode will save a bit of power in situations where you do not need a network connection.

A little bit, but not much. It's still worth doing though.
Hope This Helps!
