SKY497 Controls and Indicators (Continued) Description Data Tag + 10 These two digits indicate, in hundreds of feet, the relative altitude of the intruder aircraft. For example, +10 means the intruder aircraft is 1,000 feet above you. A positive data tag is displayed above the traffic symbol to emphasize that the intruder aircraft is above your aircraft. Similarly, a negative data tag is displayed below the traffic symbol.

Operating Instructions SKY497 Switch Between Standby and Normal Operating Mode You must switch out of standby if you want the SKY497 to display traffic information. The ability to switch out of standby on the ground in conjunction with the above display mode is especially useful for scanning the airspace around the airport before takeoff. 1. To switch into normal operating mode from the standby screen (figure 2-3), press the button labeled >OPR.
Operating Instructions SKY497 Change the Altitude Display Mode You can change the altitude display mode anytime your aircraft is not in standby. 1. Press the altitude display mode button to toggle the altitude display mode between above, normal, and below. With each press of the button, the screen changes to display the traffic detected within the chosen altitude display range. (See figure 2-9.) The name of the chosen altitude display mode (ABV, NRM, or BLW) is displayed next to the button.
Operating Instructions SKY497 Switch Between SKYWATCH and STORMSCOPE Modes (Optional) If you have a STORMSCOPE WX-1000 installed with the SKY497, you can switch between SKYWATCH and STORMSCOPE screens (figures 1-2 and 1-3) using the remote SKYWATCH/STORMSCOPE mode switch. Once in STORMSCOPE mode, you can use the buttons on the display bezel to control STORMSCOPE functions.
SKY497 Operating Instructions Monitor the activity of any traffic displayed. Keep in mind the following points when watching traffic on the display: • Traffic Prioritizing – The SKY497 can track up to 30 intruder aircraft simultaneously, but to reduce clutter, it displays only the 8 most threatening aircraft of those tracked.
Operating Instructions SKY497 4. Remove power from the SKY497 at the circuit breaker. If you haven’t already manually switched into STORMSCOPE mode, the display will automatically switch into STORMSCOPE mode once you disconnect power from the SKY497 regardless of the position of the SKYWATCH/STORMSCOPE mode switch. 5. Contact your authorized BFGoodrich Avionics Systems dealer for troubleshooting help.
Principles of Operation SKY497 Chapter 3 Principles of Operation Introduction This chapter describes Traffic Advisory (TA) criteria and other factors that affect the display of traffic symbols. Table 3-1 summarizes the criteria necessary for the SKY497 to display a TA. Figures 3-1 through 3-3 show the TA zones for various aircraft configurations. Table 3-1. Ten Situations in Which a Traffic Advisory Will Occur The SKY497 Will Issue a Traffic Advisory… And Your If Your Aircraft’s No.
Principles of Operation SKY497 Sensitivity Level A Sensitivity level A consists of two criteria for displaying a TA: 1. The intruder aircraft enters into a cylinder of airspace surrounding your aircraft defined by a 0.2 nmi horizontal radius and a height of ±600 ft from your aircraft. (See figures 3-1 and 3-2.) OR… 2.

Display Interpretation SKY497 Chapter 4 Display Interpretation Introduction This chapter explains the meaning of several sample screens. If you have a STORMSCOPE WX-1000 installed, refer to the STORMSCOPE WX-1000 pilot’s guide for interpretation of the STORMSCOPE screens. The abbreviation CPA used in some of the figures means closest point of approach. OFF + 10 Traffic Advisory: Intruder aircraft at 9 o’clock, 2 nmi away, 200 ft below you, ascending at a rate greater than 500 fpm.
Display Interpretation SKY497 OFF Other Traffic: Non-altitudereporting intruder aircraft at 7 o’clock, 5 nmi away. No immediate threat. ABV BRT STB 6nm Figure 4-3. Non-Altitude-Reporting Traffic OFF BRT SKY497 Standby TEST When in standby, the SKY497 does not transmit interrogations or track intruder aircraft. Press the button labeled >OPR to begin tracking intruder aircraft. OPR Figure 4-4.
