b. Using the force applicator, deflect the transducer vane forward (UP) to the (Pot 0) TG
force measured in step 10 in Section 7.24.1. If the stall warning horn is already ON, turn
(Pot 0) CCW until the horn is OFF and then slowly turn the (Pot 0) CW until the horn is
ON again. Press down on the vane until the horn is OFF and slowly release the vane. If
the horn is not ON when the vane is released, turn the (Pot 0) until the horn is ON.
c. Reduce the force on the vane to 0 TG and reposition the force applicator to apply a
downward force on the vane.
d. Calculate the (Pot 3) TG force by adding +10 TG to the (Pot 0) TG force.
Example:
If the (Pot 0) force is -4 TG, add +10 TG and the (Pot 3) force is +6 TG.
e. Install voltmeter leads between TP18 (Lo) and TP19 (Hi) of the SK100360 Breakout
Box.
f. Apply the calculated (Pot 3) TG force to the vane with the force applicator.
g. Adjust the (Pot 3) on the lift computer until the voltage output from TP18 (Lo) and TP19
(Hi) reads 2.2 ± 0.2 VDC on the voltmeter.
h. Return the force on the force applicator to 0 TG.
10. Approach Flaps calibration:
a. Run the flaps to the APPROACH position.
b. Using the force applicator, deflect the transducer vane forward (UP) to the (Pot 1) TG
force measured in step 11 in Section 7.24.1. If the stall warning horn is already ON, turn
the (Pot 1) CCW until the horn is OFF and then slowly turn the (Pot 1) CW until the horn
is ON again. Press down on the vane until the horn is OFF and slowly release the vane. If
the horn is not ON when the vane is released, turn the (Pot 1) until the horn is ON.
c. Reduce the force on the vane to 0 TG and reposition the force applicator to apply a
downward force on the vane.
d. Calculate the (Pot 4) TG force by adding +14 TG to the (Pot 1) TG force.
Example:
If the (Pot 1) force is -9 TG, add +14 TG and the (Pot 4) force is +5 TG.
e. Install voltmeter leads between TP18 (Lo) and TP19 (Hi) of the SK100360 Breakout
Box.
f. Apply the calculated (Pot 4) TG force to the vane with the force gram applicator.
g. Adjust the (Pot 4) on the lift computer until the voltage output from TP18 (Lo) and TP19
(Hi) reads 2.2 ± 0.2 VDC on the voltmeter.
h. Return the force on the force applicator to 0 TG.
11. Flaps Extended calibration:
a. Run the flaps to the FULL DOWN position.
b. Using the force applicator, deflect the transducer vane forward (UP) to the (Pot 2) TG
force measured in step 12 in Section 7.24.1. If the stall warning horn is already ON, turn
the (Pot 2) CCW until the horn is OFF and then slowly turn the (Pot 2) CW until the horn
is ON again. Press down on the vane until the horn is OFF and slowly release the vane. If
the horn is not ON when the vane is released, turn the (Pot 2) until the horn is ON.
c. Reduce the force on the vane to 0 TG and reposition the force applicator to apply a
downward force on the vane.
d. Calculate the (Pot 5) TG force by adding +17 TG to the (Pot 2) setting.
