As per the rulebook, page 27:
“If moving past the other figure, use one of the [Straight] Maneuver Templates to continue the flying creature’s move past the other figure, even if it was using a [Bank] or [Turn] when it bumped the ground figure.”
The word “continue” is meant to imply that you still use the original template, but use the [Straight] template just to keep going until you make it past to the other side.
Keep in mind that this is optional. The flying creature can choose to stop in front of the ground creature if it chooses.
