AVIONICS LIMITED II Section Paragraph INSTALLATION 2.1 GENERAL INFORMATION This section provides interconnect diagrams and installation criteria for the INS 422 navigation receiver. By following these instructions, the INS 422 will perform as specified and provide excellent performance to meets its design. 2.2 UNPACKING AND INSPECTING EQUIPMENT Exercise care when unpacking the equipment. Visually inspect the unit for any evidence of damage incurred during shipping.
AVIONICS 2.3 LIMITED EQUIPMENT INSTALLATION The INS 422 installation will conform to standards designated by the customer, installing agency and existing conditions as to the unit location and type of installation. However, the following suggestions should be considered before installing the INS 422. 2.3.
AVIONICS LIMITED 2.3.2.1 PANEL LOCATION The INS 422 is rigidly mounted in a standard 3.125” round cutout on the aircraft panel. Once a location has been selected, a visual inspection should be made of the area directly behind the panel which, will be occupied by the INS 422 and harness assembly for obvious obstructions such as heater ducts, control cables, fuel and oil lines or any other obstruction. Pay particular attention to the control yoke assembly.
AVIONICS LIMITED 2.3.3 NAV/GLIDESLOPE/MARKER ANTENNA INSTALLATION Navigation, Glideslope and Marker antennae should be installed as per FAA Advisory Circular AC43.13-2A Methods and Guidelines and the appropriate manufacturers instructions. Navigation couplers can be utilized to provide multiple system operation from one navigation antenna. 2.3.4 AUDIO INTERFACE Audio output for the INS 422 is rated at 10 MV into a 600 Ohm load.
AVIONICS 2.4 LIMITED POST- INSTALLATION CHECKOUT An operation performance flight test should be made after the installation to ensure satisfactory performance of the equipment in its intended environment. The installing agency using appropriate ramp testing equipment should verify proper unit operation prior to actual flight testing.
AVIONICS 2.4.1 LIMITED POST-INSTALLATION ADJUSTMENTS The INS 422 has been calibrated and adjusted at the factory. Additional adjustments required by the installing agency (with specialized, precision test equipment) to fine tune the Localizer and Glideslope display indications can be accessed through the front panel as follows: A.
AVIONICS 2.4.2 LIMITED PERIODIC MAINTENANCE The INS 422 does not require any regular general maintenance except as described in this section. A. VOR Checks VOR accuracy checks required for IFR flight must be performed on the INS 422 every 30 days to verify the unit does not exceed the allowable bearing error. Refer to CFR 14 paragraph 91.171 B. Cleaning The Display Filter The display filter on the front bezel of the INS 422 can be cleaned with a soft cloth dampened with clean water.
AVIONICS LIMITED Section III OPERATION Paragraph 3.1 POWER ON UNIT It is recommended that power to the INS 422 be turned on only after engine start-up. This procedure increases the reliability of the solid-state circuitry. The ON-VOL/MKR-MUTE/BRG control on the lower left side of the display is used to power up the INS 422 system by rotating the knob slightly clockwise out of the off “detent” position.
AVIONICS 3.3 LIMITED OPERATING INSTRUCTIONS 3.3.1 INITIAL TURN ON On initial activation, the frequency 112.50 MHz is tuned and displayed. The three Marker lights, Localizer course and Glidepath deviation light bars will be momentarily fully illuminated (when off frequency or out of reception range). This self-test feature provides a visual display to confirm that all lamps are operable. 3.3.2 ILS MODE When the test and visual inspection has been completed, select the desired frequency with the “Freq.
AVIONICS LIMITED The appropriate Marker lamp will illuminate with associated audio tone: Outer Marker (Blue) 400 Hz Middle Marker (Amber) 1300 Hz Fan Marker (White) 3000 Hz Indicating the aircraft position throughout the approach. With Marker audio present, a marker audio mute feature can be activated by pushing in momentarily (lightly) on the ON-VOL/MKR-MUTE/BRG knob. This will shut off the marker audio for a few seconds and then audio will resume if it is still present.
AVIONICS LIMITED 3.3.3 VOR MODE The frequencies for VOR stations are assigned from 108.00 MHz to 117.95 MHz. When the VOR frequency is selected and the aircraft is out of range of the VOR station, a flagged condition indicated by a full light bar in both directions vertical and horizontal will be observed on the indicator. When the aircraft comes into range of the VOR station, a horizontal (string of lamps) deflection will be observed.
