Altitude Conversion in Guided Flight Mode

  1. During flight in auto mode

  2. Right click on the map and execute fly here, At this time, the flight mode is changed to Guided.

  3. The plane takes a turn flight at the point I designate.

  4. I want to lower the altitude little by little, so I right-click on the map (the location I specified in item 3) - Fly here - and enter the altitude to fly.

  5. The plane hopes to descend slowly while flying in a large circle, but this will almost always be a dive of more than 45 degrees.

  6. In a situation where plane flying in a big circle from a point on the map, I want the elevation to change slowly.

Can this be modified with a simple parameter setting? If yes, what parameters?
