In Arkham City there are points covered with Bats flying everywhere where you can switch characters from Catwoman to Batman. It's the same with Catwoman, there's a point with Cats laying on the ground usually positioned on rooftops.
Well, I've played this game at my friends house. All I remember how to get a helicopter is by climbing up all the ladders and rooftops that you can, but, I do not recommend flying the helicopter.
