SECTION 1: INSTRUMENT DESCRIPTION
1.1 GENERAL DESCRIPTION
An attitude indicator, also known as a gyro horizon or articial horizon, is an instrument used in an aircraft to inform
the pilot of the orientation of the airplane relative to the earth. It indicates pitch (fore and aft tilt) and bank (side to
side tilt), and is a primary instrument for ight in instrument meteorological conditions. Attitude indicators also have
signicant applications under visual ight rules.
The KMC 2000-2 Digital Electronic Attitude Indicator receives digital information from a series of accelerometers
which is processed to actuate a display that has two dimensions of freedom, simultaneously displaying pitch and
bank. The display is colored to indicate the horizon as the division between the two colored segments (blue for sky
and black for ground), and is intended to be intuitive to use. The actual bank angle is calibrated around the circum-
ference of the instrument dial. The pitch angle is indicated by a series of calibration lines, each representing 5° or
10° of pitch.
On the attitude indicator you will see two yellow horizontal lines with a dot between them. The horizontal lines repre-
sent the wings and the dot represents the nose of the aircraft. If the symbolic airplane dot is above the horizon line
(more blue background) - the aircraft is nose up. If the symbolic airplane dot is below the horizon line (more black
background) - the aircraft is nose down. When the dot and wings are on the horizon line, you are in level ight. If the
lines representing the wings roll to the left or the right, the aircraft is probably starting a turn.
The magnetic direction indicator gives the pilot a general heading in relation to magnetic north. This is used as a
reference and does not indicate true geographical north. The pilot should be aware of the difference of magnetic
heading versus true heading in the area of operation in order to compensate as required.
The slip/skid indicator is a digital version of the traditional glass and ball inclinometer. The ball gives an indication
of whether the aircraft is slipping, skidding or in balanced ight. The ball’s movement is caused by the force of grav-
ity and the aircraft’s centripetal acceleration. When the ball is centered in the middle, the aircraft is in coordinated
ight. If the ball is on the inside (wing down side) of a turn, the aircraft is slipping. And nally, when the ball is on the
outside (wing up side) of the turn, the aircraft is skidding.
1.2 PHYSICAL DESCRIPTION
The KMC 2000-2 is a direct reading attitude indicating instrument which provides a real-time visual display of
aircraft pitch and roll in reference to the horizon. The instrument utilizes a series of accelerometers and complex
mathematical formulas to determine pitch and roll. The attitude indicator is not required to conform to FAA TSO
certication with light sport aircraft.
The instrument also has an integrated magnetic direction indicator to comply with the ASTM required equipment for
night ight in a Light Sport Aircraft. An additional digital slip/skid indicator is also displayed. Refer to table 1 below
for leading particulars.

Figure 1.1, Display Features
1.3 DISPLAY FEATURES
See Figure 1.2 below for typical display features.
ROLL DIAL
The Roll Dial shows the degree of roll against the Roll Pointer.
PITCH DIAL
Indicates the pitch angle as determined by the Symbolic Airplane dot.
ROLL POINTER
The Roll Pointer points to the degree of roll against the Roll Dial.
SYMBOLIC AIRPLANE
Represents the orientation of the aircraft’s wings and nose in relation to the horizon. The dot represents the
nose of the aircraft and indicates Pitch. The wings indicate roll.
HORIZON LINE
The line where the ground (black) meets the sky (blue) indicates earth horizon relative to aircraft pitch and roll.
SLIP INDICATOR
Also referred to as an Inclinometer, the Slip Indicator measures the relative strength of the force of gravity and
the force of inertia caused by a turn; thus indicating whether the aircraft is slipping or skidding.
DIMMER / MODE BUTTONS
Individual buttons will dim (left button) or brighten (right button) the display screen when pressed individually.
Press and hold both buttons simultaneously to change screen mode.
HEADING
Indicates current magnetic heading.

SECTION 2: OPERATION
2.1 PRE-FLIGHT
The following describes the start-up process:
2.2 SCREEN MODES
At any time, you may change to any of the 3 screen modes. Press and hold BOTH Dimmer/Mode buttons simulta-
neously to scroll through the 3 screens; the Instrument screen, the ICON Logo screen, the Instrument Data screen
and back to the Instrument screen. The instrument continues to run in the background so ight data will not be lost.
NOTE
You can instantly return to the Instrument Screen from the ICON Logo and Instrument Data Screens
by pressing any one of the two Brightness/Mode buttons.
INSTRUMENT SCREEN
When the instrument is fully functional, the standard attitude indicator screen
will appear. This includes the magnetic direction indicator in the lower left corner
and the slip indicator in the lower center.
ERROR SCREEN
After a few seconds, the Error screen may appear momentarily.
While the instrument is calculating pitch and roll angles, and magnetic head-
ing, the Error screen may be displayed. The red “X” and the “Excess rotation
Rate” warning indicates that the instrument reading is not reliable.
Figure 2.2, Screen Modes
ICON LOGO SCREEN
When power is applied to the instrument, the ICON logo splash screen is
shown. This indicates that the instrument is powering up.

2.3 DIMMER CONTROLS
The screen brightness can be modied by using the Dimmer/Mode buttons. When in the Instrument screen, press
the left button to dim the screen. To brighten the screen, press the right button. You can tap the buttons to move up
or down in stepped intervals of brightness or hold the button down until the desired brightness is reached.
NOTE
The instrument can only be dimmed or brightened while in the Instrument mode. However, once you have
dimmed the instrument, all modes will be dimmed accordingly. Pushing the Dim (left) or Brighten (right)
button will put you into the Instrument screen mode and will adjust the screen as needed.
2.4 INSTRUMENT CARE
The most easily damaged part of your instrument is the screen. Special care should be taken when cleaning the
screen to prevent scratches and other damage. Avoid touching the screen at all times.
To clean light spots and dust, use a soft, lint free cotton cloth slightly moistened with distilled water.
For harder to clean spots, use a 50/50 solution of isopropyl alcohol and distilled water. Vinegar may also be used in
a 50% solution with water. You may also use cleaners approved for LCD TV’s and laptop computer screens.
Always apply the cleaner to the cloth and not the screen.
-CAUTION-
●Do Not use paper towels, facial tissue or napkins. These products are made from recycled paper
and may contain metals and wood chips that will scratch the screen.
●Do Not use acetone or cleaners containing ammonia.
By avoiding all screen contact and by using proper cleaning methods, the user will be rewarded with many years
of service.
2.5 FLIGHT LIMITATIONS
There are no ight limitations to the KMC 2000 attitude indicator. The instrument will operate in a full 360 degrees
of turn and may be used in light aerobatic type maneuvers.
Extreme turns may cause the instrument display to temporarily disable itself. This is indicated by a red “X” across
the screen and an “Exceed Bank Angle” warning notice at the bottom of the screen (see gure 2-1 Error screen).
This means that the instrument reading is temporarily not reliable. The instrument should automatically reset the
display within 3 to 10 seconds. This situation is due to the speed the processor repaints the display. The attitude
sensors are not affected and there is no action required by the pilot.
2.6 SERVICE
The KMC 2000-2 is totally digital and uses no moving parts as with traditional mechanical gyroscopic instruments.
Because of this, there is no service schedule.
Service is only required when indication accuracy exceeds the tolerance listed in Table 1, or there are discrepancies
with the modes/functions detailed in this Operation Guide.

SECTION 3: TROUBLESHOOTING
3.1 INSTRUMENT MAGNETIC COMPENSATION
The KMC 2000-2 senses the earth’s magnetic eld for the magnetic direction indicator. Because the engine and
other instruments generate electrical elds that may interfere with the magnetic eld, The instrument has been
calibrated to compensate for this electrical interference to enhance accuracy.
If, in the unlikely event that the magnetic direction indicator becomes erratic or when deviations in the heading is
noticed, due to new electrical interference, the instrument can be re-calibrated.
Refer to the following steps to re-calibrate the magnetic heading:
1. When in ight and at least 3 minutes after turning on the instrument.
2. Press and hold the two buttons at the same time until the message “Gathering Mag Data” is shown on the
display (approximately 10 seconds). Note that the display will rotate through the 3 screen modes until the mes-
sage appears. This operation resets any previous compensation and the instrument begins to gather data for
10 minutes to perform the magnetic compensation.
3. During the 10 minutes the instrument is gathering data, perform two 360 degree turns to the right and two 360
degree turns to the left.
4. When the 10 minutes time is over, the instrument will show the message “Mag Data SAVED”.
5. This message will remain visible until the instrument has been restarted. The instrument is now calibrated for
the magnetic eld of the aircraft (hard iron correction).
NOTE
During the re-calibration process, the instrument could behave erratically and may not be relied on
for accurate directional indication.
