It's not Pilotwings 64, but the original Pilotwings for the SNES is set to hit the Wii U Virtual Console pretty soon, with a tentative July 4th release date. Like most Wii U SNES games it'll be priced at $7.99, with the option to upgrade (if you own the Wii VC original) for $1.50.
This game was pretty earth shattering at release due to the insane Mode 7 visuals, but by today's standards, it will look pretty dated to some. If you're into flight simulators and don't mind retro games though, you may enjoy it.
