Table 12 is a matrix that shows typical protection times and volumes for 7.0 units. (These
include units with dash numbers that end in 07 or greater.) When radio (AGL) and pressure
altitude (MSL) select different sensitivity levels, the TCAS uses the lower level.

Description
Sensitivity
Level 0
Level 0
In automatic mode, sensitivity level is selected by altitude or by ground
command. Sensitivity level 0 is selected manually when the control unit
function switch is in the TA/RA mode position (in-flight). This selection
enables all TCAS surveillance, tracking, and resolution advisory functions.
command. Sensitivity level 0 is selected manually when the control unit
function switch is in the TA/RA mode position (in-flight). This selection
enables all TCAS surveillance, tracking, and resolution advisory functions.
Sensitivity
Level 1
Level 1
In sensitivity level 1, TCAS stops all surveillance, tracking, and resolution
advisory functions. The traffic advisory display is blank except for a
STANDBY mode annunciation. Sensitivity level 1 requires one of the
parameters that follows:
(1)
advisory functions. The traffic advisory display is blank except for a
STANDBY mode annunciation. Sensitivity level 1 requires one of the
parameters that follows:
(1)
On the control unit or MCD, the
function switch is set to ATC 1 TEST,
ATC 1 STBY, ATC 1 ON, an ATC 2 position, or the ALT SOURCE switch
is in the OFF position.
is in the OFF position.
(2) TCAS is in STANDBY mode or TEST mode.
(3) TCAS has failed.
(3) TCAS has failed.
Sensitivity
Level 2
Level 2
In sensitivity level 2, TCAS performs surveillance and tracking functions and
provides traffic advisories only. Sensitivity level 2 requires one of the
parameters that follows:
(1) Own aircraft is in-flight and TA or TA/RA is below 1000 feet AGL.
(2) Own aircraft is in-flight and transponder/TCAS control unit is set to TA.
(3) Own aircraft is on the ground and transponder/TCAS control unit is set
provides traffic advisories only. Sensitivity level 2 requires one of the
parameters that follows:
(1) Own aircraft is in-flight and TA or TA/RA is below 1000 feet AGL.
(2) Own aircraft is in-flight and transponder/TCAS control unit is set to TA.
(3) Own aircraft is on the ground and transponder/TCAS control unit is set
to TA or TA/RA.
Sensitivity
Level 3, 4,
5, 6, and 7
Level 3, 4,
5, 6, and 7
In sensitivity levels 3 thru 7, TCAS performs surveillance and tracking
functions and supplies both resolution advisories and traffic advisories. Note
that the transponder TCAS control panel must be in the TA/RA mode for
these sensitivity levels. The parameters for sensitivity levels 3 thru 7 are
based on own aircraft altitude as follows:
(1) Sensitivity level 3 - Own aircraft altitude is between 1,000 and 2,350 feet
functions and supplies both resolution advisories and traffic advisories. Note
that the transponder TCAS control panel must be in the TA/RA mode for
these sensitivity levels. The parameters for sensitivity levels 3 thru 7 are
based on own aircraft altitude as follows:
(1) Sensitivity level 3 - Own aircraft altitude is between 1,000 and 2,350 feet
AGL (radio altitude).
(2) Sensitivity level 4 - Own aircraft altitude is between 2,350 feet AGL and
5,000 feet MSL (pressure altitude).
(3) Sensitivity level 5 - Own aircraft altitude is not higher than 10,000 feet
MSL.
(4) Sensitivity level 6 - Own aircraft altitude is 10,000 to 20,000 feet MSL.
(5) Sensitivity level 7 - Own aircraft altitude is above 20,000 feet MSL.
(5) Sensitivity level 7 - Own aircraft altitude is above 20,000 feet MSL.
