Answer 2

Explanation:

It is about to land at a location and the pilot is doing a high orbit and then a low orbit to scope at the landing zone. (not sure how many circles you meant). It is a news helicopter and there is something newsworthy that it is filming, so the pilot is circling to keep the camera on the event.
