I did a loiter in my fixed wing and I set my next waypoint to be 300m higher. This next waypoint was several km’s away. I wanted the aircraft to gradually climb to the next waypoint over the distance of the leg. However I noticed the aircraft climb aggressively after the completion of the loiter to get to higher altitude. Is this normal behaviour following a loiter? If so, I will need to set another waypoint after the loiter at the same altitude before it commences the gradual climb.
