 During the second 90° of the change of heading, the pitch angle is held constant, while the bank angle is smoothly decreased to reach 0° of bank, the end of the turn and return to straight-and-level flight at exactly the reciprocal heading (180° away from the heading at the start of the maneuver), and with the airspeed close to the stall speed.The aircraft should not lose altitude during the last part of the maneuver, nor during the recovery, when engine power may be used to re-establish normal cruising speed on the new heading.The decreasing bank angle together with the decreasing airspeed during the second half of the chandelle will maintain a constant turn rate.
