how do i load the boxes?

I like the name

@furla The CRS is short for Course. Heading and Course are two seperate things but both steer the plane in the direction you want to go. Heading is, that the plane is just flying in the direction of the compass number. It does not check for wind or other issues that might let you drift away from your course. Course is, as i just said, the actual course you want to fly to a certain point, with which the aircraft will always calculate for wind, drift, steering inputs, etc. to get you to that exact point. So they are both important in aviation but a little different. Also the CRS button activates the AP to fly to the Coordinates you put in via the Keyboard.

what is the CRS?

Very cool though!

I fucking hate the Atlas Corporation............................... (reference)
