7.24.2 Calibration of the C-05606-1 Lift Computer
NOTE
For calibration of the stall warning points, reference King Air 200 Series
Maintenance Manual, listed in Table 1-2, section 27-31-00. The procedures
listed here are provided to augment the King Air 200 Series Maintenance
Manual and allow the installer to adjust the stall warning points (Pots 0, 1 and
2) and LAA output (Pots 3, 4 and 5) simultaneously to save setup time.
1. Connect the SK100360 breakout box between the Safe Flight P/N C-05606-1 lift computer and
the mating aircraft harness (see Figure 7-15).
2. Make sure the stall warning heater system is turned OFF.
3. Remove the potentiometer access cover plate from the lift computer.
4. Simulate an in-flight condition as follows: Bypass the landing gear safety switch by connecting
an electrical ground to TP7 of the breakout box. This is best accomplished by placing a jumper
between TP2 and TP7 of the breakout box.
CAUTION
The anchor tab of the force applicator can be bent if the knob that applies
tension to the transducer mounting plate is over tightened. Use care when
installing the force applicator to prevent damage to the anchor tab. Refer
to the data supplied with the force applicator.
5. Install the appropriate gauge, 1952-1 gauge (0.5 to 3 gram scale) or the 1952-3 gauge
(2 to 15 gram scale), in the force applicator (see Figure 7-16), onto the left wing in accordance
with the manufacturer's instructions. Refer to the data supplied with the force applicator. The
force arm must be positioned so that the applied force is within 1/32 inch of the transducer vane
tip. Forces applied forward or up will be classified as minus values. Forces applied aft or down
will be classified as plus values. Make sure that the vane is free to move with the force
applicator.
6. Apply external power to the aircraft.
7. Place the BATT master switch to the ON position.
8. Verify the STALL WARN circuit breaker on the copilot circuit breaker panel is set.
WARNING:
Make sure that all personnel are clear of the flap area before proceeding
with these procedures.
