For example it would be useful in practicing landings to snapshot the plane position / game state during approach. Then restore it as needed allowing the landing to be practiced multiple times?
You can also do it using Sky Dolly.

Well usually for me I used to select a destination runway and I just “Set as Arrival” without any departure points. It should give me a spawning point not far from the runway already facing the same heading.
Once I’m done with my landing practice, I just reset the flight and I’m back in the air just before landing again.
If that doesn’t work anymore, I find having a short flight from Macau Airport to Hong-Kong is a nice place to practice take off and landing with only a few minutes.
