TCAS II Pilot’s Guide
Effective Date 2/04 006-08499-0000 Rev 7 69
WARNINGS AND LIMITATIONS (CONT’D)
• TCAS can be wired to inhibit display of traffic on the ground
when your own aircraft is below 1700 ±50’ AGL. If configured this
way, aircraft on the ground disappear as you descend through
1650’ and reappear on the traffic display as you climb above
above 1750’. TCAS II designates “On-Ground” traffic by compar-
ing own aircraft radio altitude and pressure altitude. Any intruder
estimated by TCAS to be within 380 feet of the ground descend-
ing or 400 feet ascending will be categorized as “On-Ground.”
If not configured this way, all On-Ground intruders are displayed
as non-threat traffic (open white diamond).
• Increase Descent Resolution Advisories are inhibited below
1450 feet AGL.
• All Resolution Advisories are inhibited below 900 feet descend-
ing or 1100 feet ascending.
• All TCAS II audio warnings are inhibited below 900 feet Radio
Altitude on approach and up to 1100 feet Radio Altitude on
departure.
CAUTIONS
Always attempt to visually clear the airspace before maneuvering
your aircraft in response to a TCAS advisory.
The TCAS installation can be wired to give GPWS and Wind
Shear higher priority than TCAS. In case of simultaneous audio
alarms, the TCAS II system is placed in TA ONLY mode and the
RA/VSI flag will show the RA OFF.
