C# flight programming

[robbie2g2 0]

Hello guys, I was wondering if anyone with knowledge or experience with C# programming for Xplane could help me out. I have been tasked to program a flight journey on Xplane using visual studio with no user control input as a mini project. Meaning that the plane has to take off do a round trip and then land by means of a C# code. So far I have managed to get the plane (cessna) to take off, maintain a heading and climb to a certain altitude. My problem now is how do I get it to follow a path and then land using C#? I would be very grateful if someone could point me to the right direction on this regard and thank u in advance.
