The above settings should be adjusted with the aircraft flying in smooth air in a stabilized
mode. Once properly adjusted correctly, these settings should not have to be changed.
7.9.2 Flight Time, Distance and Totalizer Counters
The EZ Pilot contains flight time and flight and distance counters and Flight time and
distance totalizers on two screens within the calibration displays menu.
7.9.2.1 Flight Time and Distance Counters
The Flight time and Flight distance counters on the first display screen and count
the time of flight and flight distance as long as a speed of 50 knots or above is
maintained. This means that the flight and distance counters do not include time
and distance information in the pre or post flight regimes. These counters can be
individually reset to zero at any time by selecting the appropriate display line with
the MODE switch (an arrow will precede the selected field) and then bumping the
L-R switch to perform the zeroing. For these timers to operate the host GPS
must be on and have achieved satellite lock. The time and distance information
is saved in non-volatile memory once each minute so if power is lost momentarily
only a maximum of 1 minute of time and distance information will be lost.
The Distance counter counts actual distance flown and measures and excursions
from the programmed flight plan. This means that if, for example, you did a 50
mile detour between two waypoints 200 miles apart, the actual distance added to
the distance counter will be 250 miles.
All distance measurements are based on nautical miles so it is recommended the
host GPS receiver be programmed to measure the distance in nautical miles vs
statute miles or kilometers.
Pressing the DISPLAY switch will advance from the Flight time and Distance
counters to the Flight Time and Distance Totalizer display
7.9.2.2 Flight Time and Distance Totalizer Displays
This display shows the total accumulated flight time and total accumulated flight
distance in nautical miles. This display cannot be reset and is saved once each
minute in nonvolatile memory.
8.0 Electrical Requirements
For your EZ Pilot to operate properly, it is important to assure that it has been installed properly.
Pay particular attention to assuring correct wire size and careful connector assembly. If
soldering, be sure to use shrink tubing to cover the solder joints, and provide support for the
harness assembly so it is not affected by vibration. If you crimp the wires, be sure to use the
proper tool.
8.1 Primary Input Power
The EZ Pilot requires an input power on pin 13 of 10 to 14 VDC at 1 amp and servo
power on pin 19 or 18 of approximately 1 amp. The EZ Pilot is internally fused and
requires wire from a circuit breaker capable of supplying approximately 3 amps. Both the
autopilot and servo power are normally supplied from the same circuit breaker. 24 gauge
wire is recommended although a larger size (22 or 20) is acceptable. The power ground
should be a minimum 24 AWG wire size and is connected to pin 11. This wire should be
the same size or larger (lower gauge number) as that used for the input power to pin 13.
