There is no way you spawn helicopter in VC.You can only find in the city on helipads.
There is not a cheat to spawn a helicopter in vice city stories.

As you cannot spawn helicopter using a cheat code.You need to download Ultimate trainer for gta Vice city.Then use it to spawn the helicopters and other vehicles.
