Ix Task C Chandelle

Front 1

C-1 Chandelle Objective

Back 1

Develop coordination, orientation, planning and accuracy of control during maximum performance flight

Front 2

C-2 Definition

Back 2

A Chandelle is a maximum performance climbing turn beginning from approximately straight and level flight and ending at the completion of a precise 180 degrees of turn in a wings level, nose high attitude at the minimum controllable airspeed

Front 3

C-3 Set Up:

Back 3

Flaps and Gear should be in the up position

Power set to cruise condition

Min Alt is 1500 AGL

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)

Front 4

C-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

C-5

Back 5

Confirm appropriate airspeed and power setting ave been established

(C-172 120 MPH)

Front 6

C-6

Back 6

Start by smoothly entering a coordinated turn with an angle of bank appropriate for the airplane

Usually not more than 30 degrees

Front 7

C-7

Back 7

After bank is established:

Smoothly apply back elevator pressure to increase pitch attitude at a constant rate and to attain the highest pitch attitude as 90 degree of turn is completed

For fixed pitch Props, smoothly apply maximum ALLOWABLE r.p.m. Constant speed Props power may be left at normal cruise

Front 8

C-8 First 90 degrees is marked by

Back 8

Maintain SET Bank Angle And Varying Pitch

Aircraft may want to continue to bank more as the maneuver continues.

Front 9

C-9

Back 9

At the arrival of the 90 degree mark from the initial heading, the pilot should begin rolling out of the bank at a constant rate while maintaining a constant pitch

Front 10

C-10 Second 90 degrees is marked by

Back 10

Set Pitch and Varying Bank Angle

Front 11

C-11

Back 11

Reduce slight bits of back pressure as the horizontal component of lift is increased

Nose of the aircraft should not rise as Pitch is set for this 90 degrees

Front 12

C-12

Back 12

Approaching the completion of the 180 degrees of turn, the pitch attitude should be noted by checking outside references and the Artificial Horizon

Hold this attitude as aircraft should be at MCA

Front 13

C-13

Back 13

During the maneuver as A/S is constantly decreasing the effects of engine torque will become more prominent Therefor Right Rudder pressure is gradually increased to control yaw

Front 14

C-14

Back 14

Through Out the Chandelle,

Watch for Coordinated Flight by periodically observing the ball in the turn and slip indicator

Front 15

C-15 For Left turn, use considerable Right Rudder

Back 15

For a Chanedlle to the Left:

To roll out of the Left turn the Left Aileron will be deflected down creating more lift to raise the Left wing creating additional drag yawing the aircraft to the LEFT

The slow A/S and high R.P.M. of the engine and P-Factor from the prop will cause a yaw to the LEFT

This will necesatate the use of more Right Rudder

Front 16

C-16 For a Right turn

Back 16

The downward deflecting aileron and Engine and Prop forces tend to neutralize each other and little to no Left rudder could be necessary to achieve a coordinated roll out of the turn. Normally just the slight releasing of some Right Rudder will be sufficient to remain coordinated

Front 17

C-17 The End of the Maneuver

Back 17

At Slow flight wings level, Right Rudder will need to be held as to maintain directional control and coordinated flight as Engine and Prop forces will pull the nose of the aircraft to the Left

Front 18

C-18

Back 18

Complete the maneuver by:

Confirming 180 degree turn completion

Verifying Aircraft is at MCA

Front 19

C-19

Back 19

Return the aircraft to straight and level flight by slowly relaxing back elevator pressure but controlling the loss of Altitude.

Slowly Adjust Rudder inputs to remain in coordinated flight condition as Airspeed increases

Maneuver is complete when aircraft is back in the pre maneuver condition at a heading change of 180 degrees at a higher than beginning altitude

C-20

Back 20

Commercial PTS

Establishes 30 degrees of bank

Roll Out on the 180 degree is within +of- 10 degrees

Resume Straight and level flight with minimum loss of altitude

Front 21

C-21 Common Errors

Back 21

Improper pitch, bank & power coordination during entry or completion

Uncoordinated use of flight controls

Improper planning & timing of pitch & bank attitude changes

Factors related to failure in achieving mazimum performance

A stall during the maneuver
