Preliminary
“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.
The
SKY899 does not track intruder aircraft approaching at a
closure rate greater than
1200 knots.
Some traffic within the chosen display range may not be displayed
due to traffic prioritizing, antenna shielding, or ground intruder
filtering.
Optimum
SKY899 performance is realized when intruder aircraft
are reporting their altitude (via a mode
C or other altitude
reporting transponder).
Monitor the activity of any traffic displayed. Keep in mind the
following points when watching traffic on the display:
• Traffic Prioritizing – The
SKY899 tracks up to 35 intruder
aircraft simultaneously, but to reduce clutter, it displays
only the
8 most threatening aircraft of those tracked.
• Ground Intruder Filtering – If a radio altimeter is
connected to the
SKY899, no traffic symbols are displayed
for traffic detected under
380 ft Above Ground Level
(AGL) when your aircraft is below 1,700 ft AGL.
• Refer to chapter
4 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 on the display. Information on the display is provided to the
flight crew as an aid in visually acquiring traffic; it is not a
replacement for
Air Traffic Control (ATC) and See & Avoid
techniques.
CAUTION
