NEVER OPERATE THE WINDSHIELD WIPERS ON A DRY WINDSHIELD - Remove the spring
tension on the hub end of the wiper arm by inserting a 1/8-inch-diameter pin through the hole
in each side of the wiper arm
.

with pitch, pitch trim, and roll servos running
Tune VHF COMM NO. 1 to a frequency appropriate for test transmissions.
Transmit
on COMM No. 1 (no
modulation is necessary).
13. Observe the G1000/GFC700 DC electrical load from the amp meter and record in Table 1 as DP3.
14. Discontinue transmitting on COM 1. Disengage Autopilot
15. Turn off windshield wipers and remove the pin from the holes in the wiper arm.

Data Point
Bus
Amps DC
DP1
Non-switchable DC electrical load (EXT PWR ON)
DP2
DC electrical load (EXT PWR ON, BATT charge, External
lights, anti-ice systems
DP3
G1000/GFC700 DC Electrical load (AFCS engaged, COM TX)
Table 1 - Measured DC Electrical Loads
17. Using the data points from Table 1, obtain the total electrical load by the following formula:
DP2 + DP3 – DP1 +2 amps = Total Electrical Load _________________ DC amps ( GWX 68
maximum power loads is 2 amps )
Verify adequate capacity of the aircraft electrical system with the addition of the G1000 and GFC 700
systems.
