1. INTRODUCTION
1.1 BACKGROUND INFORMATION:
The KLR 10 system is primarily designed to improve operational
safety of airplanes by increasing pilot awareness of available lift
during operations at high angles of attack (AOA). Additional benefits
may be reaped by identifying or maximizing aircraft performance
based on a fixed AOA or a constant CL, such as maximum range,
best glide, climbs and approaches.
AOA: Angle of Attack is the difference between the
airfoil’s cord line (a line from the leading edge to
the trailing edge of the wing) and the relative
wind (the inverse of the aircraft flight path).
CL: Coefficient of Lift is a relative measure of an
airfoil’s lifting capabilities.
CLmax: Coefficient of Lift Maximum is the AOA which if
exceeded will cause the airfoil to stall.
CD: Coefficient of Drag is a measure of total drag,
induced and parasite drag.
CL/CD:Coefficient of Lift over Coefficient of Drag is a
ratio between lift and drag.
CL/CD Maximum: The maximum lift-to-drag ratio at which
maximum range and maximum glide distance will
be found for propeller airplanes.

Page 1-2 Rev 0 Jul 2013
1.2 SYSTEM DESCRIPTION
The KLR 10 measures pressure at two points from an AOA probe
mounted solidly to the wing in reference to the cord of the wing that
conveys changing differential pressures, via sense lines, to the
KLR 10 IF module. The IF module converts the pressures into an
electronic signal that is transmitted to the KLR 10 indicator.
The KLR 10 indicator interprets the signal and turns on the
appropriate segments to convey the AOA or lift information to the
pilot. In addition to the visual display, the IF module also has an I/O
connector that allows connection of the remote audio interface
system that provides warning annunciations in the pilot’s headset.
The KLR 10 draws a minimal current of less than approximately ¼
amp (250mA) of electrical power. For the system to operate
correctly, it must be supplied electrical power within a range of 12 to
28VDC and be calibrated correctly.
The AOA probe must be kept clear of any obstructions and be
mounted securely, in clean air flow. The final AOA probe to wing
angle will be determined by the amount the bottom of the wing varies
from parallel to the cord of the wing. For most aircraft, the starting
angle is 50 degrees from the leading edge of the AOA probe
mounting plate. The KLR 10 system will adjust for differences within
a limited electrical signal range. AOA Probe angle readjustment
may be needed to allow for full scale electronic calibration.
Probe heat is an option and if installed requires approximately 7.8
amps of electrical power at 12 or 24VDC to operate. To extend the
life of the probe heat element, it is recommended that the probe heat
not be used for prolonged periods while on the ground.

2. KLR 10 CONTROLS
2.1 POWER UP SELF TEST
When power is first applied to the KLR 10, the KLR 10 runs through
a built in test. During the test, the segments cycle up and then down
the display. When the test is complete, the segments turn off and the
KLR 10 annunciates “AOA test complete”.

2.3 THE KLR 10 DISPLAY SEGMENTS:
The KLR 10 display has chevron and bar styled LED-driven color-
coded segments; which once correctly calibrated, illuminate
corresponding to the AOA of the aircraft. The display will respond to
the linear changes of the aircraft’s AOA from Cruise, up to Stall and
gives a repeatable, instantaneously changing segment
representation of that range. The display will illuminate a series of
transitional segments from no segments to the Green Bar
(“Cruise” indication for the aircraft located at the bottom
of the display),and on through to the flashing Red Arrow
“” (stall indication for the aircraft located at the top of
the display).
A correctly calibrated KLR 10 will provide a linear increase in AOA
indication as the aircraft slows. The final “Too slow Too Slow” alert
with flashing red arrow MUST be active prior to the actual
aerodynamic stall. Ensure during post-calibration testing that the
final KLR 10 alert state is displayed prior to any stall indications.
The 10 possible segment combinations are listed below. Every
aircraft will correlate the lit segment or combination of segments to
the specific aircraft’s AOA dynamics, once calibrated. The
relationship of when and which combination shows is unique to the
aircraft’s AOA and can be accurately correlated ONLY when in-flight.

2.4 DISPLAY BRIGHTNESS CALIBRATION
The KLR 10 indicator is preset at the factory for daytime/nighttime
brightness levels. If the maximum/minimum brightness levels need to
be changes in your aircraft follow the following procedure to preset
both the daytime and nighttime display brightness levels while on the
ground.
Enter the Brightness calibration mode as follows:
•Ensure that power is not applied to the KLR 10.
•Depress and hold the Brightness button on the KLR 10
indicator then apply power to the KLR 10.
•Continue to depress the Brightness button for about 6 seconds
after power has been applied.
•Release the Brightness button.
The system enters its self test causing the colored segment
illumination routine. All segments are illuminated one by one
upwards and then one by one downwards ending with all the
segments being illuminated.
The system is now in Brightness calibration mode.
•With a light applied directly to the photo diode on the KLR 10
indicator for at least 5 seconds, press and release the
Brightness button until the display is at its maximum brightness.
Cycling past the maximum brightness of the colored segments will
cause the indicator to return to the minimum level. There are 16
brightness steps that are sequenced through, increasing brightness
at each step.
•Wait 5 seconds for the unit to store the setting then remove the
light from the KLR 10 indicator.
The display’s brightness will change to the lower brightness level
unless the low light setting was set to maximum brightness or the
cockpit is in daylight.

KLR 10 Pilot’s Guide
KLR 10 Controls P/N D201306000109
Page 2-8 Rev 0 Jul 2013
•Next, cover the photo diode on the display for at least 5 seconds
with your thumb or a piece of black electrical tape, quickly press
and release the Brightness button on the KLR 10 indicator until
it’s at a minimum or lowest level.
•Wait 5 seconds for the unit to store the setting than remove your
thumb or tape.
•Observe that the display’s brightness level changes from dim to
bright when light is applied and removed from the photo diode.
•Remove power, wait a few seconds and re-apply power.
The system will enter its self test, display illumination routine in
which all colored segments are illuminated one by one upwards and
then one by one downwards. The system enters the active mode if
calibration has been completed or the inactive pre-calibration display
mode, needing OAA and Cruise calibration.
2.5 BRIGHTNESS ADJUSTMENT WHEN ACTIVE
To change brightness when the unit is active, quickly push and
release the Brightness button until the desired brightness level is
reached.
There are 16 brightness levels and a photo cell to detect
“nighttime” and “daytime”ambient light levels and automatically
switches to the stored level. The new brightness levels are stored
when powered off.
2.6 IN-FLIGHT CALIBRATION FLOW CHARTS
The following flow charts contain an abbreviation version of the in-

Good
OAA Set
point?
In-Flight calibration requires the pilot to climb to a
safe altitude for slow flight maneuvers. The pilot will
fly the aircraft to the condition of Optimum Alpha
Angle (OAA): Aircraft is at OAA, when:
1.)
Aircraft is at a safe altitude for slow flight
maneuvers.
2.)
Minimum controllable flight, lower power
setting, (such as a down wind or landing
pattern power setting).
3.) Able to hold altitude, 0 Vertical Speed, not
descending, zero sink (5 to 10 fpm climb
OK if your aircraft looses fl
ight control
stability at 0 VS).
4.) Full aileron, elevator and rudder control, not in
a buffet
, pilot to identify the set point by
pitching back slowly to a pitch no longer able
to climb but able to hold altitude with full
control of the airplane.
Once a good OAA Set point has
been achieved, the pilot
continues to STEP 2 and MUST
enter into the Cruise Calibration
Mode or repeat the OAA Set

3. OPERATION
The KLR 10 Lift Reserve Indicator improves pilot awareness of
available lift during operation at high angles of attack such as slow
flight, takeoffs and landings.
The system is calibrated with the aircraft in the clean configuration.
When flaps are extended, the KLR 10 AOA indications will be more
conservative (showing higher AOA) when flaps are extended.
This section explains the procedures to be flown to develop a
reference list that shows the segments that are lit on the KLR 10
Indicator during the different phases of flight.
Section 3.1 on page 3-2 gives the procedure to practice a high AOA
flight regime with the use of the KLR 10 Indicator.
Section 3.2 on page 3-7 gives the procedures to practice takeoffs
and climb outs with the use of the KLR 10 Indicator.
Section 3.3 on page 3-11 gives the procedures to maintain best glide
speed with the use of the KLR 10 Indicator.
Section 3.4 on page 3-13 gives the procedures to practice
approaches with the use of the KLR 10 Indicator.

Page 3-2 Rev 0 Jul 2013
3.1 PRACTICE HIGH AOA FLIGHT REGIME
To familiarize you with the KLR 10 indications during a high AOA
flight regime, use the following outline as a guide:
•Plan a flight to an area where high AOA flight can be performed
without any undue hazards (reference § 91.303 & § 91.305).
•Review the stall recovery procedures for your aircraft. If an
inadvertent stall occurs, immediately recover from the stall using
per your training and the aircraft manufacturers instructions. At
no time is a stall required to correctly calibrate or operate the
KLR 10.
•Acquaint yourself with the KLR 10 indicator and its functions.
•Preflight and operate the aircraft as you would normally.
•When in an area and at a safe altitude that safe operation at
slow flight can be performed and the air is smooth, perform
clearing turns to ensure the area is clear.
•Follow the aircraft procedures and slow the aircraft, in the clean
configuration (No Flaps).
•Maintain coordination.
•Maintain altitude.
•Monitor the KLR 10 indicator.
•Slow to just above the stall. If any stall warning device activates
or an impending aerodynamic stall is imminent, recover
immediately using the appropriate procedure for your aircraft.
•Return to normal flight.
•Using the abbreviations from table 2-2 on page 2-4, write down
the illuminated segments in the space provided below and in the
Table 3-1: Observed Indications Chart on page 3-17.
