Je to manévr na vytracení výšky bez přílišného vzdálení se od místa přistání. Přeletíš nad místo přistání, snížíš kolektiv, hodíš vrtulník na bok do ostré zatáčky a dostaneš se rychle tou zatáčkou zase před místo přistání, kde podrovnáš. V knížce Rattler One Seven je to popsáno, jak to létali ve Vietnamu na Hueyi
„…we would fly over the LZ so that wind was 90 degrees off the left side of the helo, altitude about 2500 feet – a good margin for safety from small arms fire. When we were directly over the LZ, we would lower the collective, and roll the bird into a steep left turn. This would set up the helicopter in a steep descending turn. Rate of descend would be 2-3000 feet/minute as we made our 450 degree turn. Within seconds of starting the approach, we would begin our roll out and be established on short final to the LZ. All we had to do was flare the helicopter while adding power, and within seconds we would be hovering in the LZ. Benefit of it was it took a mninimum amount of time to get into the LZ, and if we get hit while the approach, we just continued down into the LZ where friendly troops were located. Many pilots would do 360 degree high overheads, but I liked the 450 better."
"...due to aerodynamics of the helicopter it was better to execute a high overhead approach in a left turn, instead of right. ..." and "...being the AC, you wanted to be on the side of the aircraft in which you were making the turn, which allowed you to see better what was taking place on the ground as you shoot your approach."
