    SKY899 Installation Manual Section 2 Installation INTRODUCTION The information and instructions provided in this manual are directed toward fixed-wing aircraft. Installation must be made by qualified personnel, in conformance with applicable government regulations. The information furnished is for convenience only. CAUTION Installing SKY899 on float-equipped aircraft can result in degraded performance.

  • Page 44: Antenna Location

    SKY899 Installation Manual ANTENNA LOCATION Location is an important factor for maximum antenna performance. Optimum location for a particular aircraft type is usually available from the aircraft manufacturer. In selecting a location, consider the following: Directional Antenna The mounting site should be on the top forward fuselage, as close to the centerline as possible, and within -10 degrees of the in-flight horizon (see Figure 2-1).

  • Page 45: Trc Location

    SKY899 Installation Manual TRC LOCATION Typically the TRC is installed in the electronics bay. In selecting a location, consider the following: Cable Length Cable runs should be as short as practicable in order to minimize potential electrical interference. Cable length to antennas must not exceed the values listed in table 1-9.

  • Page 59: Cable Requirements And Fabrication

    SKY899 Installation Manual CABLE REQUIREMENTS AND FABRICATION The installer will supply and fabricate all system cables. Cable specifications and approved vendors are provided in paragraph 1.7, equipment required but not supplied. Appendix A defines the electrical characteristics of all input and output signals and identifies the cable requirements for each signal. Required connectors and contact pins are supplied in the installation kits.

  • Page 60: Antenna Cables

    SKY899 Installation Manual 2.6.1 Antenna Cables NOTES 1. If you fabricate your own cables, you must verify that the attenuation and VSWR does not exceed the specified values. 2. To add strain relief and alleviate stress caused by aircraft vibration, place 4-6 inches (10.2 to 15.2 cm) of heat shrink tubing over each antenna connector and cable.

  • Page 61: Data Cable

    SKY899 Installation Manual 2.6.3 Data Cable RS-232, RS-422, and ARINC-429 data cables are #22 AWG (minimum) twisted, shielded cables. The shield shall be grounded at both ends and at all breaks. Cable runs should be as short as practicable. 2.6.4 Heading Input Cable The heading input cable connects the TRC899 to the aircraft synchro heading system (refer to the Interconnect Wiring Diagram, Figure 2-2, Figure 2-3 or Figure 2-4).

  • Page 62: Power Cable

    SKY899 Installation Manual 2.6.5 Power Cable For the power cable, use #16 AWG (minimum) twisted shielded pair cable (Beldon 83322, Alpha 2826/2, or equivalent). The power cable runs from the aircraft circuit breaker panel to the TRC. The power cable is connected to the TRC using the MS3126F12-3S connector included in the TRC installation kit.

    SKY899 Installation Manual Figure 2-6: Display Cable The sub-cable color-coded jackets and shields should be left on the sub-cables as close to the connectors as practical to provide the required shielding and to identify the sub-cables. 2.6.8 Converting Existing Aircraft Wiring from SKY497 to SKY899 In some instances, it may be desirable to convert an existing SKY497 installation to a SKY899 installation.

  • Page 64: Aircraft Discrete Inputs

    SKY899 Installation Manual AIRCRAFT DISCRETE INPUTS The aircraft discrete inputs are used for ViP™ extended audio callout, audio suppression and to assist in determining the aircraft's phase of flight or flight condition (e.g., on ground or in flight). The discrete inputs are configured in the service menu and saved to the System Configuration Module.

  • Page 65: Squat Switch (Weight-On-Wheels)

    SKY899 Installation Manual 2.7.4 Squat Switch (Weight-On-Wheels) This input is to be connected to the squat switch (weight-on-wheels) to sense when the aircraft is on the ground. NOTE If the aircraft is not equipped with a squat switch, it is recommended that a squat switch or an alternate switch be installed.

  • Page 66: General Sensor Inputs

    SKY899 Installation Manual 2.9.1 General Sensor Inputs The TRC can use four general sensor inputs: barometric altimeter, radio altimeter, magnetic heading, and GPS navigation data. Five receive channels have been designated for these inputs and will allow various combinations of speed and equipment types. It is also possible for multiple data inputs (barometric altimeter, radio altimeter, magnetic heading and GPS navigation) from one source to be received on one channel (e.g., ARINC-429 superbus).

  • Page 67: Alternate Display Output

    SKY899 Installation Manual 2.9.3 Alternate Display Output The TRC has one transmit channel designated for alternate displays (i.e., EFIS, MFD and weather radar via a Radar Graphics Computer). The transmitter speed is fixed at 100 kHz. A maximum (typical) of ten loads (displays) can be connected to the output channel.

  • Page 68: Gilham Code (Encoding Altimeter)

    SKY899 Installation Manual 2.11.1 Gilham Code (Encoding Altimeter) These signals are Gilham code inputs coming from an airdata computer or altitude digitizer (encoding altimeter). These 11 lines may be connected in parallel with the aircraft transponder. If the aircraft is equipped with selectable altitude encoders, connect the altitude inputs so that SKY899 is always connected to the selected encoder.

    SKY899 Installation Manual D.3 CHECKOUT PROCEDURE The T-49C Flightline Tester simulates ground based secondary surveillance radar (SSR) when the TCAS INTRUDER selector switch is in the ATCRBS/Mode-S XPDR TEST position. When the T-49C intruder type switch is set to ATCRBS, the unit responds to ATCRBS Mode C interrogations. A varying delay time, controlled from the microprocessor, delays the replies returned to the SKY899 from as far as 14 nautical miles and as close as a few hundred feet.
