the target track vector and may delay display of the intruder information. However,
intruder distance and altitude typically remain relatively accurate and may be used to
assist in spotting traffic. The following errors are common examples:
• When the client or intruder aircraft maneuvers excessively or abruptly, the tracking
algorithm may report incorrect horizontal position until the maneuvering aircraft
stabilizes.
• When a rapidly closing intruder is on a course that intercepts the client aircraft
course at a shallow angle (either overtaking or head-on) and either aircraft abruptly
changes course within 0.25 nm, TIS-A may display the intruder aircraft on the
incorrect side of the client aircraft.
These are rare occurrences and are typically resolved within a few radar sweeps once
the client/intruder aircraft course stabilizes.
Pilots using TIS-A can provide valuable assistance in the correction of malfunctions
by reporting observations of undesirable performance. Reports should identify the time
of observation, location, type and identity of the aircraft, and describe the condition
observed. Reports should also include the type of transponder and transponder
software version. Since TIS-A performance is monitored by maintenance personnel,
not ATC, malfunctions should be reported in the following ways:
