Can the Goodrich Skywatch HP Traffic Avoidance System be certified as TCAS I?
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.
Will the L3/Goodrich Skywatch interface with the Bendix/King KMD-250/550/850 MFDs?
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.
Will the Skywatch HP (SKY899) directly replace the standard Skywatch (SKY497)?
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.
Is an STC required for installation of a TAS or TCAS I System?
No, an STC is not required for TAS (Traffic Awareness) and/or TCAS I installations on Part 91 and Part 135 aircraft. FAA order 8300.10 provides guidance for a follow on field approval by the FAA. An FAA approved Aircraft Flight Manual Supplement is required as well.
How can I display the traffic information from the Skywatch traffic system?
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.
