4 Data Tag
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. If the
intruder is at the same altitude as your aircraft, 00 will be displayed
above the traffic symbol.
The data tag for a vertically out of range TA stays at the maximum or
minimum altitude number of the current altitude display mode until the
intruder aircraft comes within the altitude limits of the altitude display
mode. The
SKY497
only displays data tags for altitude reporting aircraft.

This aural component of a traffic advisory is announced once over the
cockpit speakers or headset when a TA aircraft is first detected.
–“Traffic Advisory System Test Passed”
This message is announced once over the cockpit speakers or headset
after the
SKY497
has passed an operator-initiated self test.
–“Traffic Advisory System Test Failed”
This message is announced once over the cockpit speakers or headset
after the
SKY497
has failed an operator-initiated self test.
Turn On the SKY497
To avoid power surges that could damage the
SKY497
and the optional
WX-1000
, start your engines before turning on the
SKY497
.
1. Turn the
OFF/BRT
knob clockwise to the desired display brightness.
The
BFG
oodrich screen (figure 2-2) appears and stays on the display until the power-
on self test is complete.
If the
SKY497
passes the test, and your aircraft has a squat switch, and your aircraft is
on the ground, the standby screen appears (figure 2-3).
If the
SKY497
passes the test, and your aircraft has a squat switch, and your aircraft is
in the air, the traffic screen appears set on the 6 nmi display range and the normal
altitude display mode (figure 2-4).
If the
SKY497
passes the test and your aircraft does not have a squat switch, the
standby screen appears (figure 2-3).
If a Failed screen similar to figure 2-5 appears, refer to the Failure Response section
on page 2-9. (For installations with an
ARINC 429
barometric altitude input, turning
on the
SKY497
during flight causes a temporary Error 20 message while the system is
syncing up to the
429
data source.)

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
.
The
SKY497
switches out of standby into the above display mode and 6 nmi range.
(See figure 2-7.)
If your aircraft has a squat switch and you don’t manually switch out of standby, the
SKY497
will automatically switch out of standby 8 to 10 seconds after takeoff.
2.To switch into standby from the traffic screen (figure 2-7), press the button
labeled
>>>>>STB
.
The
SKY497
goes into standby and the display switches back to the standby screen.
If your aircraft has a squat switch, the
>STB
button label is not displayed while you’re
airborne and the
SKY497
will not go into standby while airborne, but will automati-
cally go into standby 24 seconds after landing. (This delay allows the
SKY497
to
remain out of standby during a touch-and-go maneuver.)
Change the Display Range
You can change the display range anytime your aircraft is not in standby.
1.Press the display range button to toggle the display range between 6 & 2
nmi. (See figures 2-7 and 2-8.)
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
nm or 6 nm) is displayed next to the button.
The
SKY497
continues to track up to 30 intruder aircraft within its maximum
surveillance range regardless of the display range selected.

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
SKY-
WATCH/STORMSCOPE
mode switch. Once in
STORMSCOPE
mode, you can use the
buttons on the display bezel to control
STORMSCOPE
functions.
If the
SKY497
is in
SKYWATCH
mode, the display will not
automatically switch into
STORMSCOPE
mode to display thun-
derstorms
or STORMSCOPE
errors: You must use the remote
SKYWATCH/STORMSCOPE
mode switch to periodically check
for thunderstorms or
STORMSCOPE
errors.
The
SKY497
does not superimpose
SKYWATCH
data on top of
STORMSCOPE
data or vice
versa; however, if the
SKY497
is in
STORMSCOPE
mode and the
SKY497
detects a
TA
, the
display automatically switches back to
SKYWATCH
mode until the
TA
goes away. Also, if
the
SKY497
is in
STORMSCOPE
mode and the
SKY497
detects a failure, the
SKY497
Failed
screen appears with a message to “Press Any Key to Ack.” Pressing any key switches the
SKY497
back to
STORMSCOPE
mode.
Observe the Display
The
SKY497
relies on information obtained from transponders
in nearby aircraft. The
SKY497
does not detect or track aircraft
which are not equipped with an operating
ATCRBS
transponder.
The
SKY497
does not track intruder aircraft approaching at a
closure rate greater than 900 knots.
Some traffic within the chosen display range may not be displayed
due to traffic prioritizing or antenna shielding.
Optimum
SKY497
performance is realized when intruder aircraft
are reporting their altitude (via a mode C or other altitude
reporting transponder).
Pilot’s Guide 2-9
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.
•Ground Target Filtering – If your aircraft has a compatible Arinc 429 radio altimeter
connected to the
SKY497
,
TA
s and other traffic symbols will not be issued for traffic
detected under 380 ft
AGL
when your aircraft is below 1,700 ft
AGL
.
•Refer to chapter 3 for a description of the
TA
criteria and other factors that affect the
display of traffic symbols.
Respond to Traffic Advisories
Do not attempt evasive maneuvers based solely on traffic informa-
tion shown on the
SKY497
display. Information on the display is
provided to the flight crew as an aid in visually acquiring traffic; it
is not a replacement for
ATC
and See & Avoid techniques.
When the
SKY497
issues a
TA
, look outside for the intruder aircraft. When you spot an
intruder aircraft, use normal right-of-way procedures to maintain separation.
Turn Off the SKY497 and the Optional WX-1000
1. Rotate the
OFF/BRT
knob on the display bezel counterclockwise until the
switch turns off.
Failure Response
All errors indicated by a
SKY497
Failed screen (figure 2-5) prevent continued operation of
the
SKY497
in
SKYWATCH
mode; however, error #20, Barometric Altitude Input, is a
recoverable error. For example, if you turn on the
SKY497
before you turn on the
barometric altitude source, a
SKY497
Failed screen will appear with error #20 and
continued operation of the
SKY497
in
SKYWATCH
mode is not possible; but when you
eventually turn on the barometric altitude source, the
SKY497
Failed screen will disappear
and operation will return to normal.
Respond to a
SKY497
Failed screen as follows:
1. If the Barometric Altitude Input error (#20) occurs, make sure the baromet-
ric 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
SKY497
.
2. If any other error occurs, or if error #20 remains after 5 minutes, write
down the error number and description.
3. If you have a
STORMSCOPE WX-1000
, you can still switch into
STORMSCOPE
mode using the remote
SKYWATCH/STORMSCOPE
mode switch.
2-10 Pilot’s Guide
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 trouble-
shooting help. Be sure to give the troubleshooting personnel the error
number and description that you wrote down in step 2.
Operate the Optional WX-1000 When the SKY497 is Removed
After removing the
SKY497
for maintenance, maintenance personnel will install a jumper
plug that will allow continued operation of the
WX-1000
.
Operate the SKY497 When the Optional WX-1000 is Removed
After removing the

Table 3-1. Ten Situations in Which a Traffic Advisory Will Occur
Sensitivity Levels
The
SKY497
uses one of two sensitivity levels, A or B, to determine when to display a
TA
.
Having two sensitivity levels allows the
SKY497
to reduce the number of nuisance
TAs
during takeoff and landing (sensitivity level A), and to maximize the detection of
TAs
during the cruise phase of your flight (sensitivity level B).
3-2 Pilot’s Guide
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.The intruder aircraft approaches your aircraft on a course that will intercept your
course within 15 or 20 seconds (within 15 seconds for a non-altitude reporting
intruder aircraft; within 20 seconds for an altitude reporting intruder aircraft).
The
SKY497
uses sensitivity level A in the following situations:
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. (Sensi-
tivity level A is not used if you have fixed landing gear and no radio altimeter.)
Sensitivity Level B
Sensitivity level B consists of two criteria for displaying a
TA
:
1.The intruder aircraft enters into a cylinder of airspace surrounding your aircraft
defined by a 0.55 nmi horizontal radius and a height of ±800 ft from your aircraft.
(See figures 3-1 through 3-3.)
OR…
2.The intruder aircraft approaches your aircraft on a course that will intercept your
course within 20 or 30 seconds (within 20 seconds for a non-altitude reporting
intruder aircraft; within 30 seconds for an altitude reporting intruder aircraft).
The
SKY497
uses sensitivity level B in the following situations:
1.Your aircraft has a radio altimeter and is above 2,000 ft
AGL
.
2.Your aircraft has no radio altimeter but its retractable landing gear is up.
3.Your aircraft has fixed landing gear and no radio altimeter.
Audio Inhibit, SKY497
This audio inhibit feature prevents the aural part of
TAs
, “traffic traffic,” from being
announced during takeoff and landing in order to minimize pilot distraction. The
corresponding
TA
symbols are still displayed.
The
SKY497
uses this audio inhibit feature in the following situations:
1.Your aircraft has a radio altimeter and you’re below 400 ft
AGL
. (See figure 3-1.)
2.Your aircraft has no radio altimeter but its retractable landing gear is down. (See figure
3-2.) (Audio is not inhibited if you have fixed landing gear and no radio altimeter.)

Audio Inhibit, GPWS
If your aircraft has a Ground Proximity Warning System (
GPWS
) interfaced with the
SKY497
and a
GPWS
alarm occurs, the
SKY497
will sense the alarm and delay the aural
“traffic, traffic” component of any
TAs
issued during the
GPWS
alarm until the alarm clears.
TA Symbol Duration
The
TA
symbol remains on screen for a minimum of 8 seconds even if the intruder aircraft
no longer meets the
TA
criteria as long as the
SKY497
continues to track the aircraft.
Ground Target Filtering
Ground target filtering reduces the clutter of visual symbols and aural announcements that
would otherwise be generated for intruder aircraft that are typically present on or near the
ground near airports.
Ground target filtering prevents the issuing of
TAs
and other traffic symbols for intruder
aircraft determined to be below 380 ft
AGL
.
The
SKY497
uses ground target filtering only if your aircraft has a radio altimeter and you’re
below 1,700 ft
AGL
.
