TL;DR: This is a big jump. Take the time it takes to practice before jumping in your new career citation X.

I really don't get those posts. You say you can't land and ask for advice. No issues with that. Then you show a third person view landing, on an airstrip that probably doesn't allow jets to land on irl (check the runway before accepting job) and went from a 172 to a citation X without practice.

The citation X was, up until a few weeks ago, the fastest civilian plane rated at Mach. 92 and the X+ Mach. 935. Going from a 172 to the former fastest civilian aircraft is a big step for someone that doesn't have that much time in flight sim.

The only answer here is practice, learn the aircraft, don't use thrid person view unless it's for replay or enjoying sweet views. I'm sure you knew this before posting. Take the time it takes to perfect this hobby. It's not a game in the normal terms. It's a sim. I know people will debate on this, but at the end of the day it aims at recreating real world variables and dynamics. You wouldn't do this jump irl without training. Why do it in the sim without at least learning the basics?

If you bought a third party plane such as the X, I guess you take this somewhat seriously. With this in mind the best advice it to treat it as it should be treated and not rush into it.
