SKY899 Installation Manual 1.3.4 Directional Antenna (NY156 P/N 805-10003-001 or NY164 P/N 805-10890-001) The directional antenna is a teardrop-shaped antenna. Connections are made through two TNC and one BNC connector. The antenna is sealed against environmental extremes and is non-repairable. To ensure a tight seal between the airframe and antenna, an O-ring seal (i.e., an O-ring groove for an MS28775-044 Oring) has been incorporated into the design.

SKY899 Installation Manual CHAPTER 2 INSTALLATION 2.1 INTRODUCTION The information and instructions provided in this section are directed toward fixed-wing aircraft. The complex nature of rotorcraft installations (e.g., antenna placement; composite versus metal blades, available ground plane, rotor mast interference, strike kits, etc.) requires that each installation be evaluated on a case-by-case basis.
PAGE 36
SKY899 Installation Manual 2.3 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: The mounting site should be on the top forward fuselage, as close to the centerline as possible, and within -10° of the in-flight horizon (see figure 2-1).

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. NOTES 1.
PAGE 45
SKY899 Installation Manual 2.6.1 Antenna Cables NOTES 1. Use of any cable not meeting BFGoodrich Avionics Systems specifications voids all system warranties. 2. If you fabricate your own cables, you must verify that the attenuation and VSWR does not exceed the specified values. 3. To add strain relief and alleviate stress caused by aircraft vibration, place 46 inches (10.2 to 15.2 cm) of heat shrink tubing over each antenna connector and cable.

SKY899 Installation Manual 2.6.6 Suppression Bus Cable For the suppression bus use any size low capacitance shielded cable. Cable runs should be as short as practicable and the shields should be grounded at both ends. 2.6.7 WX-1000/SKY497 Display and WX-1000 Processor Cable The display cable connects the TRC to the WX-1000/SKY497 Display. Cable specifications are listed below (see paragraph 1.7 for cable vendors).

SKY899 Installation Manual 2.7 AIRCRAFT DISCRETE INPUTS The aircraft discrete inputs are used to assist in determining the aircraft's phase of flight or flight condition (e.g., on ground or in flight). Inputs are diode isolated inside the TRC, do not install isolation diodes externally. The active or inactive state of the inputs can be high or low, they will be saved in the System Configuration Module during system setup using the service menu. 2.7.

SKY899 Installation Manual NOTE If the aircraft is not equipped with a squat switch, it is recommended that a squat switch be installed. Squat switch connection: SQUAT P1-24 If a squat switch is not available, this input could be tied to an airspeed switch inline with the pitot system as an alternate input for the squat switch. In this configuration care should be taken to ensure the switch is set to trigger at a speed consistent with take-off and landing.

SKY899 Installation Manual 2.9 ARINC-429 The ARINC-429 interface can be divided into four sections: general sensor inputs, mode S transponder input/output, alternate display output and future input/output options. The TRC has seven receive channels and three transmit channels that are used to accomplish the various interfaces. However, two receiver and two transmitter channels are not used at this time (future option). ARINC-429 labels accepted and transmitted are listed in tables A-3 and A-4.
PAGE 52
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 RGC250). The transmitter speed is fixed at 100 kHz. The display driver must be selected via the service menu. The display drivers control the ranges and information that will be presented on the alternate display. The drivers are listed in table 2-1 along with their specifications.

SKY899 Installation Manual 2.11 BAROMETRIC (UNCORRECTED) ALTITUDE INPUTS The TRC requires an uncorrected barometric altimeter input. The barometric altitude can be gilham code or ARINC-429 (air data computer (ADC)). NOTES 1.

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.
