    System Installation Manual - KLR 10 Lift Reserve Indicator 1 GENERAL READ ME FIRST!! Important Notes to Avoid Common Errors Probe Placement PLANNING NOTE: The AOA probe must be positioned where it will be in clear, undisturbed airflow through all normal flight maneuvers. The probe must be at least 2 feet outside the propeller arc.

  • Page 10: Calibration

    CALIBRATION WARNING: On certified aircraft, the KLR 10 system should be calibrated to be slightly conservative to the certificated stall warning system. This means that the final KLR 10 visual (flashing red down arrow) and aural (“Too Slow! Too Slow!” annunciation) should occur just before the aircraft stall warning system activates.
  • Page 11 System Installation Manual - KLR 10 Lift Reserve Indicator CALIBRATION NOTE: There are three calibration set points for the KLR 10. The ZERO set point, the OAA set point, and the CRUISE set point. The ZERO set point is done ONE TIME immediately after installation while the aircraft is in the hangar with no air movement over the probe.

  • Page 12: Objective

    Product Nonconformance. All Products repaired or replaced are warranted only for the unexpired portion of the original warranty period. BendixKing offers a two year warranty from date of purchase against manufacturer defect for material and labor. After expiration of standard warranty, repair coverage will be available for a fixed fee of $200 per occurrence until five years from date of purchase.

  • Page 13: Available Kits And Components

    A complete KLR 10 SYSTEM contains one kit from Table 1-1, one AOA Probe from Table 1-3, and one Indicator Mount from Table 1-4. There are 5 different KLR 10 kits that can be ordered from Table 1-1 that differ only in the length of the Blue and White Hose Kit and the size of the Mounting Plate. The components for these kits are found in Table 1-2.

  • Page 14: System Description

    1.8 SYSTEM DESCRIPTION The KLR 10 measures pressure at two points from an Angle of Attack (AOA) probe mounted to the wing in reference to the wing chord that conveys changing pressures, via sense lines, to the KLR 10 IF module.

  • Page 15: Restrictions And Limitations

    6. No operational credit may be taken for such items as reduced approach speed and shorter landing distances. 7. The KLR 10 is required to have a placard located in plain view, that is unable to be altered or obstructed, and that must state the following phrase exactly with no changes: "Not for use as a primary instrument for flight".

    CAUTION The KLR 10 indicator CANNOT be placed in the cockpit in such a manner as to obstruct the pilot's view or cause distraction. Listed below are four different installation scenarios. Find and complete the one that pertains to your installation.

  • Page 22: Establish The Location For The If Module

     The IF module must be bonded to the airframe (grounded for shielding).  The IF module must be mounted within six feet of the KLR 10 Indicator.  The IF module must be mounted within six feet of the power source or the optional on/off switch.

  • Page 23: Figure 2-1: Aoa Probe In Wing

    System Installation Manual - KLR 10 Lift Reserve Indicator Figure 2-1: AOA Probe in Wing NOTE: Remove the inspection cover and use it as a template to cut the mounting plate to the same shape and drill the same holes. If required, install a “doubler” plate for strength.

  • Page 24: Establish A Plan To Route The Sense Lines

    The KLR 10 requires less than ¼ Ampere (AMP) (250 mA) of electrical power within its acceptable voltage range of 12-28 VDC. Our recommendation is to have the KLR 10 get power from the avionics bus through an on/off switch in series with the positive lead for the control module (this would offer some protection from surges during starts and the on/off switch would enhance operational flexibility).

  • Page 37: Setup And Calibration

    AOA system is calibrated by an indication of illuminated Optimum Alpha Angle (OAA): The term BendixKing identifies as a set point for calibration of the AOA system at a 30% safe margin above Stall. This set point is easily identified, in flight, as 1.3Vs and is identified by the illumination of the segment approximately at the middle of the display.

  • Page 42: Calibration Flight Overview

    Review the stall recovery and minimum controllable flight procedures for your aircraft. If an inadvertent stall occurs, immediately recover from the stall per your training and the aircraft manufacturers instructions. At no time is a stall required to correctly calibrate or operate the KLR 10. Setup and Calibration Pub.
  • Page 43 NOTE: The OAA set point calibration and the Cruise set point calibration can be practiced on the ground. NOTE: While KLR 10 in-flight calibration can be accomplished by a solo pilot, it is advisable that the pilot flying focuses on safely and correctly achieving the calibration set points while a second person assists in performing the indicator calibration.

  • Page 44: In-Flight Optimum Alpha Angle (Oaa) Calibration

    To enter an OAA Set Point, press and release the Calibration Set (CAL SET) push button using a pencil or other small blunt pointer on the KLR 10 indicator when the aircraft is flown at OAA. NOTE: This operation can be repeated as many times as desired at this point to continuously attempt a new OAA Set Point, as long as the system is in the OAA Calibration Mode.

  • Page 45: Invalid Set Points

    System Installation Manual - KLR 10 Lift Reserve Indicator Invalid Set Points • The KLR 10 indicator returns to an inactive state, discards the attempted set point (values out of range). • If the AOA probe angle is too low, the KLR 10 indicator’s flashes three times and announces “Invalid Set Point”.
