    01/04, 02/04 or higher will not report negative values of altitude on the ARINC 429 digital bus unless expressly configured to do so. This feature is required for installations with Honeywell EFIS 40/ 50. One of these two unit versions (-0101 or -0202) must be used when interfacing the digital output of the KRA 405B to equipment which expect non-negative values.

    KRA 405B RADAR ALTIMETER INSTALLATION MANUAL GENERAL INFORMATION This section contains general suggestions and information to consider before installation of the KRA 405B. Close adherence to these suggestions will assure optimum performance from the equipment. The conditions and tests required for the TSO and MOPS approval of this article are minimum performance standards.

  • Page 28: Configurable Parameters

    Failure to provide cooling to the equipment will lead to increased avionics maintenance costs and may also void the Honeywell warranty. CONFIGURABLE PARAMETERS The installer may alter some of the operational characteristics of the KRA 405B by installing a CM 2000 Configuration Module that has been programmed with customized preferences.

    KRA 405B RADAR ALTIMETER INSTALLATION MANUAL A calibration in an excessively noisy environment will not be accepted by the KRA 405B. A post calibration altitude of thir- ty to one hundred feet indicates a failed calibration. If this condition occurs, the calibration must be completed in a dif- ferent location.

The following procedure duplicates a flight altitude greater than 2,500 feet AGL in order to find these RF leakage paths.

Re-bond the antenna if the point- er is now stowed. If the indicator pointer still does not stow, this in- dicates an RF cable or connector problem.
  • Page 47 KRA 405B RADAR ALTIMETER INSTALLATION MANUAL (3) Test Procedure Connect the test equipment as shown in 405B TEST EQUIPMENT installation. Adjust the variable attenuator to 0 dBm (this setting yields approximately 65 dBm loop loss). The KNI 415/ 416 should indicate 900 to 1100 feet. Slowly increase the variable attenuator until the KNI 415/416 pointer goes clockwise behind the mask.
