Insert Picture

The purpose of lazy eights Drawing of 2 half circles

  • Is designed to develop the proper coordination of the flight controls across a wide range of airspeeds and attitudes

  • flight control pressures are constantly changing

  • Similar to S-turns across the road

  • The longitudinal axis of the airplane traces a symmetrical eight on its side with segments of the eight above and below the horizon

Procedures

Setup

  1. Select an altitude that will allow the maneuver to be completed no lower than 1500’ AGL.

  2. Perform the PRE-MANEUVER FLOW and make a position report (see page 2-26).

  3. Adjust the pitch and power to maintain altitude and 105 KIAS (approx. 2350 RPM). Re-trim as necessary.

  4. Select 45°, 90°, and 135° reference points on or out toward the horizon

    1. Make to not have them to close to your position

Entry/ Maneuver 

  1. From straight and level flight, initiate a climbing turn (simultaneously increase bank and pitch slowly) in the direction of the 45° reference point. 

    1. At the 45° reference point the maximum pitch up (highest) attitude (approx. 18-20°) should be achieved with a 15° bank angle continuing to increase to 30°.

  2. From the 45° reference point, while allowing the bank angle to continue increasing, 

    1. allow the pitch to decrease so that at the 90° reference point the maximum bank angle (30°) is achieved and the pitch attitude is passing through level flight at minimum airspeed (5-10 kts. above VS).

  3. From the 90oreference point, 

    1. allow the pitch attitude to continue decreasing and

    2.  initiate a slow decrease in the bank angle, continuing a descending turn in the direction of the 135° reference point.

    3.  At the 135° reference point, the maximum pitch down (lowest) attitude (approx. 18-20°) should be achieved with a 15° bank angle continuing to decrease to 0°.

  4. From the 135° reference point,

    1.  continue decreasing the bank angle while allowing the pitch to increase 

    2. so that the airplane returns to the entry airspeed and altitude by the 180oreference point.

Rudder control/ coordination

  • during the climbing portion of the maneuver considerable rudder pressure will be needed to remain coordinated. 

  • This will be required to counteract torque at the top of the eight in both the left and right turns. The pressure is greatest at the top of the turns.


Common Errors

  • Poor selection of reference points

  • Uncoordinated use of flight controls

  • Unsymmetrical loops resulting from poorly planned pitch and bank attitude changes

  • Inconsistent airspeed and altitude at key points

  • Loss of orientation

  • Excessive deviation from reference points


Conclusion

  • The purpose of lazy eights

  • Procedures

  • Common Errors
