During a ground reference maneuver, if the groundspeed is doubled while the bank angle remains constant, the radius of turn will

When practicing a rectangular course near an airport with its long sides oriented parallel to the runway, similar to the airport traffic pattern, if the wind is 20 knots directly from the runway heading and true airspeed is 100 knots, the groundspeed on the downwind leg of the rectangular course will be

When practicing a rectangular course near an airport that utilizes a standard left-hand traffic pattern, the turns of the rectangular course should be

What is the primary purpose of ground reference maneuvers?

When performing the north leg of a rectangular course during a ground reference maneuver, aligned with a north-south road, with a 15-knot wind from the west and true airspeed of 90 knots, the approximate heading required to maintain the ground track directly along the road is
