This tutorial is rather simple and quick (but can be very challenging at first).
Here we are tasked with Marshelling duty to help guide the plane to its correct parking spot and to help it stop in the correct place by using the commands we have available.
Be aware, however, that the SlowDown/Stop part is what makes this more challenging as it takes some time for the full thing to happen and therefore practice and timing may be required before you start to get it in the right place. ^-^
Hope this is short and clear enough to be helpful if you need a quick guide!
