Turn off backward flight

Im a complete novice with a new Spark wanting to avoid ever crashing.
I have turned off “backward flight” as a beginner, but what does that mean? What happens when I push the right joyslick down with backward flight off? Does the Spark turn around 180 degrees the other way and go forward? Im confused! Many thanks for some help!

That will prevent the Spark from flying backward when using an automated flight mode like ActiveTrack.

The Spark will move backward.

Many thanks. That’s clear now. I get worried when I read all the posts about drones going haywire and being lost and want to avoid that!!
