Thank you very much for taking the time to reply. I've been building my knowledge thanks to this forum and of course numerous youtube videos. Today I finally realized
I could unlock restricted zones and after some back and forth learning from the web, was able to fly in an area that I thought was off-limits.
You’ve achieved one of life’s small victories...congrats! I know the frustration of not being able to take off, so unlocking is still a delight to me. Keep in mind that sometimes, when you’re on the edge of an authorization zone, you’ll need to walk away from the zone a little to achieve an unlock.
Two meters seems about right. Once you’re a little below that, you‘re initiating an auto-land. And unless you’re in an empty paved parking lot, the zone below two meters tends to have greater potential for obstacles (foliage, signage, people).
