The first time you play, you will be given the controls of the helicopter, which will be in a position to allow you to perform your will with ease. You can use the left and right controls to move the helicopter and the up control to fly it. When you start flying, you will be given a visual representation of the environment that you are flying in, so that you can easily navigate and see where you are in the world. 

In order to complete your mission, you will have to fly to the required location and perform the task that is given to you. For example, if you are given the task to pick up a package that is located at a certain location, you will have to fly to that location and find the package.
