     2.               DFE3.2 – Operate manual propeller pitch control during ground and flight operations
            1.        operates manual propeller pitch control on the ground within the limitations and conditions specified in AFM and POH, ensuring:
                   1.          idle RPM within limits;
                   2.         propeller RPM responds appropriately to throttle;
                   3.       engine RPM is within limitations when take-off power is set;
            2.        operates manual propeller pitch control in flight within the limitations and conditions specified in AFM and POH and:
                   1.          sets RPM is set as required;
                   2.         monitors RPM remains within specified limits;
                   3.       synchronises engine RPM using propeller control on multi-engine aircraft;
                   4.       avoids oil congelation in cold weather operations by cycling engine RPM.
     3.               DFE3.3 – Manage abnormal and emergency procedures for a manual propeller pitch control
            1.        identifies abnormal or emergency operations of manual propeller pitch control or CSU;
            2.        maintains control of engine RPM;
            3.         performs appropriate abnormal or emergency procedures;
            4.        feathers and unfeathers propeller.

 2.                     Range of variables
        1.        activities are performed in accordance with published procedures;
        2.        day VFR in variable weather conditions;
        3.         approved aircraft fitted with tail wheel or conventional undercarriage;
        4.        single- and multi-engine aircraft;
        5.        piston or diesel engine;
        6.          featherable or non-featherable propeller;
        7.        CSU with or without counterweights;
        8.        simulated abnormal and emergency situations;
        9.          simulated hazardous weather.

 3.                     Underpinning knowledge of the following:
        1.        effects of loss of oil pressure to the CSU;
        2.        effects of loss of oil pressure on the pitch of the propeller (if applicable);
        3.         effects of counterweights on engine RPM (when applicable);
        4.        the function of oil pressure on the CSU fitted to the aircraft;
        5.        the function of the fine and coarse pitch stops;
        6.          the effect that failure of the fine pitch stops may cause in the aircraft type flown;
        7.        the effects of the use of carburettor heat on an aircraft fitted with a CSU;
        8.        propeller over-speed in an aircraft fitted with a CSU;
        9.          indications of engine ice in an engine fitted with a CSU;
       10.          indications that carburettor ice has been cleared in an engine fitted with a CSU;
       11.         effects on manifold pressure of reducing engine RPM in a normally aspirated engine below full throttle height.
