SKY899 Pilot’s Guide

3-5

Preliminary

With each press of the button, the screen changes to display

the traffic detected within the chosen display range. The

numerical value of the chosen display range (

2, 6, or 15 nm)

is displayed next to the button.

The

SKY899 continues to track up to 35 intruder aircraft

within its maximum horizontal surveillance range (

35 nmi

radius) regardless of the display range selected.

Change the Vertical Display Mode

You can change the vertical display mode when the SKY899 is

in normal operating mode.

1. Press the vertical display mode button to toggle between

above, normal, below, and unrestricted.

With each press of the button, the screen changes to display

the traffic detected within the chosen vertical display mode

(figure

1-5). The name of the chosen vertical display mode

(

ABV, NRM, BLW, or UNR) is displayed next to the button.

The

SKY899 continues to track up to 35 intruder aircraft

within its maximum vertical surveillance range (±

10,000 ft)

regardless of the vertical display mode selected.

Switch Between SKYWATCH &

Stormscope

If you have a Stormscope WX-1000 installed with the SKY899,

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.

If the

SKY899 is in SKYWATCH mode, the display will not auto-

matically switch into

Stormscope mode to display thunderstorms or

Stormscope errors. Use the remote SKYWATCH/Stormscope mode

switch to periodically check for thunderstorms or

Stormscope errors.

The

SKY899 does not superimpose SKYWATCH data on top of

Stormscope data or vice versa; however, if the SKY899 is in

Stormscope mode and the SKY899 detects a TA, the display

automatically switches to

SKYWATCH mode until the TA goes

away. Also, if the

SKY899 is in Stormscope mode and the SKY899

detects a failure, a special SKY899 Failed screen appears that

doesn’t have a

TEST button label, but does display the message

Observe the Display Chapter 3 – Operating Instructions “Press Any Key to Ack.” Pressing any button or waiting 10 seconds switches the SKY899 back to Stormscope mode. Observe the Display The SKY899 relies on information obtained from transponders in nearby aircraft. The SKY899 does not detect or track aircraft which are not equipped with an operating Air Traffic Control Radar Beacon System (ATCRBS) transponder.

Message Response Chapter 3 – Operating Instructions When the SKY899 issues a TA, look outside for the intruder aircraft. When you spot an intruder aircraft, use normal rightof-way procedures to maintain separation. Turn Off the SKY899 and the Optional WX-1000 Rotate the OFF/BRT knob on the display bezel counterclockwise until the switch turns off.

Respond to a Failed System Chapter 3 – Operating Instructions If you see a SKY899 Failed screen, respond as follows: 1. If the Barometric Altitude Input error (#20) occurs, make sure the barometric altitude source has been turned on and given enough time to warm up. Most #20 errors are due to the failure of equipment external to the SKY899. y r 2.

Respond to a Degraded System Chapter 3 – Operating Instructions If you have a WX-1000 Stormscope and you haven’t already manually switched into Stormscope mode, the display will automatically switch into Stormscope mode once you disconnect power from the SKY899 regardless of the position of the SKYWATCH/Stormscope mode switch. 13. Contact your authorized BFGoodrich Avionics Systems dealer for troubleshooting help.

Once the faults responsible for the degraded condition are corrected, the MSG symbol disappears from the traffic screen, but remains on the Standby screen. Pressing the message button in this case on the Standby screen displays the message screen with no messages (figure 3-9). y r 3.

Chapter 4 Principles of Operation Introduction a n y r This chapter describes, lists, and illustrates Traffic Advisory (TA) criteria and other factors that affect the display of traffic symbols including Automatic Dependent Surveillance Broadcast (ADS-B). Table 4-1 on the next page summarizes the criteria necessary for the SKY899 to display a TA. Sensitivity Levels m il i The SKY899 uses one of two sensitivity levels, A or B, to determine when to display a TA.

TA Criteria Chapter 4 – Principles of Operation Table 4-1. Fourteen Situations in Which a Traffic Advisory Will Occur The SKY899 Will Issue a Traffic Advisory… And Your And Your If Your Aircraft’s Landing No. Aircraft… Altitude Is… Gear Is… 1 has a radio altimeter* below 2000 ft AGL 2 3 above 2000 ft AGL 4 5 does not have a radio altimeter* 6 down 7 up 8 9 11 12 13 14 P e r Sensitivity Level A And An Intruder Aircraft Is Detected… within a 0.
PAGE 9
Sensitivity Levels Chapter 4 – Principles of Operation The SKY899 uses sensitivity level A in the following situations (corresponds to numbers 1, 2, 5, 6, 13, and 14 in table 4-1): 1. Your aircraft has a radio altimeter and is below 2,000 ft AGL. 2. Your aircraft has no radio altimeter but its retractable landing gear is down. y r 3. Your aircraft has no radio altimeter, a fixed landing gear, and your ground speed is available and is less than 120 knots.

Ground Intruder Filtering Chapter 4 – Principles of Operation TA Symbol Duration A TA symbol remains on the screen for at least 8 seconds, even if the intruder aircraft no longer meets the TA criteria, as long as the SKY899 continues to track the aircraft. Ground Intruder Filtering y r Ground intruder filtering reduces the clutter of visual symbols and aural announcements that would otherwise be generated for intruder aircraft typically present on or near the ground near airports.
PAGE 13
ADS-B Chapter 4 – Principles of Operation The SKY899 anticipates the future Free Flight environment by continuously monitoring the dedicated data link frequency (1090 MHz) for ADS-B mode S extended squitter messages within 50 nmi. These messages are broadcast, without interrogation, from aircraft with ADS-B-capable mode S transponders. The SKY899 does not require a mode S transponder, ADS-Bcapable or otherwise, to perform its ADS-B surveillance.
