A lazy eight airplane maneuver is NOT an aerobatic maneuver ^[1], and does not incorporate a "wingover" which is a completely different type of maneuver. The maneuver is not 'abrupt' and uses pitch and bank angles that are within the range of 'normal flight. ' The lazy eight is a coordination maneuver required for FAA commercial pilot certification. It involves two 180° turns with constantly changing pitch, bank, altitude, and airspeed.

Starting at the recommended entry airspeed, the object of the maneuver is to steadily decrease airspeed to just above a stall at the 90-degree point of the turn. Then to steadily increase the airspeed during the second 90 degrees of the turn, using a constant power setting. Simultaneously the turn must have a constantly increasing bank angle during the first 90 degrees and constantly decreasing bank angle in the second 90 degrees of the turn. At the 180-degree point, altitude and airspeed must match the entry altitude and airspeed. Doing two 180-degree turns in this manner completes the maneuver.

"Lazy"

Though I have no source to cite, I have always supposed that the expression "Lazy 8" comes from the use of "lazy" in just this way in cattle branding. Someone could look into this. -- Thnidu (talk) 16:47, 22 October 2015 (UTC)[reply]
