Yes. Depending on the indicator configuration utilized, the Skywatch HP System can be certified for TCAS I operation. Sextant IVSIs, Collins EFIS systems (provided that EFIS has traffic software in the processor unit) can display the traffic information from the Skywatch HP for TCAS I approval. Proline IV and Proline 21 MFDs are approved interfaces as well. Various radars, with the use of the Goodrich RGC-250 radar graphics computer, can display this traffic information as well. These MFDs in include the Avidyne Flightmax, Honeywell KMD-550/850, UPS Aviation MX20 and the Goodrich i-Link MFD. Garmin series units such as the GNS-430 and GNS-530 GPS/Nav/Comms are approved for traffic advisory TSO C147 but not for TCAS I TSO C118.
No. Although both the Skywatch and Skywatch HP use the same antenna, optional display and processor mounting tray, the processor connector is different. In order to upgrade a Skywatch system the Skywatch HP system, you must change and wire the 100 pin connector for the HP processor. In addition, the HP processor uses a configuration module for parameter settings while the original processor used strappings. The HP processor can also accept an analog radio altitude input for aircraft so equipped.
Yes, the KMD-250, KMD-550, and KMD-850 Multi Function Displays will all display traffic information from a Skywatch (TRC497) or Skywatch HP (TRC899) processor. However, the Skywatch processors do not accept ARINC 429 control from the KMD units for Test (TST), Standy (SBY), and ON controls. The TRAFFIC CONTROL on the Traffic Setup Page of the KMD MFD must be set to DISABLED. In addition, the installer must provide two push buttons to control the operating mode of the Skywatch processor unit. These buttons provide a momentary connection to aircraft ground when pressed and should be labeled as indicated.
No. The mounting rack and connector for the system processors (TRC899 and TRC497) are the same. In addition, both systems utilize the same NY-156 antenna (non TCAS I). However, the wiring of the connector for each processor is different. Therefore, upgrading the SKY497 (Skywatch) to SKY899 (Skywatch HP) would be a wiring change only.
No, an STC is not required for TAS (Traffic Awareness) and/or TCAS I installations on Part 91 and Part 135 aircraft. FAA order 8900.1 provides guidance for a follow on field approval by the FAA. An FAA approved Aircraft Flight Manual Supplement is required as well.

The Skywatch 497 and Skywatch 899 (HP) are compatible with multiple indicators and displays. The original display interface was the WX-1000 Stormscope display Part Numbers 78-8060-5900-8 and 78-8060-5900-9. A toggle switch was installed between the Stormscope and Skywatch to switch the display between the 2 systems. The Skywatch system can also be interfaced to some weather radar indicators using L3's RGC250/350 series radar graphics computer. The current, most common display option is to interface the Skywatch to modern Multi-Function Displays (MFD) which accept standard traffic information. Some integrated nav/comm systems such as the Garmin GNS430/530 series systems are cabable of displaying traffic information as well.

In order for the Skywatch / Skywatch HP NY-156 or NY-164 antenna to fit on specific airframes, an adapter plate may be required. Specific part number installation kits with the necessary adapter plates are available. Please refer to the following chart for aircraft applications and kit part numbers.
