When a flight plan is in effect, iFly places your aircraft icon at the beginning of the flight plan. So, create a flight plan with just one waypoint: where you want the plane to be. (BTW, if it's an airport, I suggest you create a waypoint slightly to the side of the airport so your aircraft icon doesn't get in the way of you clicking on the airport itself.). Then close the flight plan page to return to the map page. Your aircraft will be where you want. At that point you can return to the flight plan page and clear the flight plan -- but I would suggest that you save it first so you can use it again in the future.
