Ix Task D Lazy Eights

Front 1

D-1 Lazy Eight Objective

Back 1

Develop perfect coordination of controls through a wide range of airspeeds and altitudes Execution of dive, climb and turn are all combinedAll of the forces on the controls are constantly changing

Front 2

D-2 Definition

Back 2

A Lazy Eight consists of 2 180 degree turns in opposite directions, while making a climb and a descent in a symmetrical pattern during each of the turns.

Front 3

D-3 Set Up:

Back 3

Flaps and Gear should be in the up position

Power set to cruise condition

Airspace behind and above clear of other air traffic

Entered from straight and level flight (or a shallow dive)

At a speed no greater than the maximum entry speed recommended by the manufacturer (usually Va)

(C-172 is IAS 120 MPH)

Identify an area with land markings at each 45 degree mark

Front 4

D-4 Start of Procedure

Back 4

Clear the Area using two procedure turns equaling at least 90 degrees in opposite directions.

Roll from one right to the next.

Use these turns to scan for traffic

Front 5

D-5

Back 5

Confirm appropriate airspeed and power setting ave been established

Will NOT add additional power for the maneuver

(C-172 120 MPH)

Front 6

D-6 Start of the maueuver

Back 6

Start with a gradual climbing turn in the direction of the 45 degree reference point.

At the 45 degree mark Aircraft should be at:

Maximum pitch-up attitude

Front 7

D-7 At the 45 Mark

Back 7

Aircraft is at Max Pitch and Max Angle of Bank

Added Right Rudder will be needed to remain coordinated due to slow A/S High Angle of Attack and High RPMs

Front 8

D-8 Towards the 90 degree mark

Back 8

Nose of aircraft should be lowered toward the 90 degree mark allowing the bank angle to increase

A slight amount of opposite aileron pressure may be required to prevent the bank from becoming too steep.

Front 9

D-9 At the 90 degree mark

Back 9

At the arrival of the 90 degree mark:

Bank Angle should be at the maximum of 30 degrees

Airspeed should be at its minimum (5 to 10 knots above stall speed

Front 10

D-10 Passing through the 90 degree

Back 10

Aircraft bank should begin to decrease gradually and the airplane's nose allowed to continue to lower so that at the 135 degree mark, the nose should be at the lowest pitch attitude.

Front 11

D-11 At the 135 degree mark

Back 11

Pitch should be at the lowest and bank angle should continue to be decreasing.

Front 12

D-12 Past the 135 degree mark

Back 12

As Speed Increases, Rudder and Aileron pressure will need to be relaxed and to simultaneously raise the nose so that it is approaching level flight.

Front 13

D-13 At the 180 degree Mark

Back 13

Aircraft should be in wings level back at starting altitude

Front 14

D-14 At the 180 degree mark

Back 14

A climbing turn in the opposite direction should be initiated.

Front 15

D-15 Things to consider

Back 15

Considerable Right Rudder gradually applied to counteract torque at the top of the 8 in both directions

Controls will be slightly crossed in right climbing turn because of the need for left aileron to prevent overbanking and right rudder overcome torque

Power setting must be correct so that the maneuver does not yield a gain or loss of Altitude at the completion of each 8

Front 16

D-16 Common Errors

Back 16

Failure to adequately clear area

Using top of engine cowl instead of the true longitudinal axis, resulting in unsymmetrical loops

Not looking for reference points

Too High or Too Low of pitch attitude

Attempting to perform the maneuver rhythmically

Allowing the aircraft for fall out of the tops of the loops

Slipping / Skidding

Failure to scan for other traffic

Front 17

D-17 Instructor Must Be able to

Back 17

Demonstrate and simultaneously explain lazy eights from an instructional standpoint

Analyze and correct simulated common errors related to lazy eights
