RA Communication and Coordination
In a case where both aircraft are TCAS equipped, the TCAS communicates with the other aircraft to coordinate evasive strategies. This coordination may occur before an advisory is issued, and is calculated for optimum safe separation using the least disruptive maneuver possible. For example, if one aircraft is in a particular vertical speed (VS) profile, it may be advantageous for that aircraft to increase or decrease its VS, as opposed to the other assuming an evasive VS. Whatever maneuver is selected, this information is communicated to other aircraft and ground facilities.
If the other aircraft is not TCAS equipped, the corrective or preventive maneuver responsibility is assumed by the TCAS-equipped aircraft, and only the ground facility communication is possible.

TCAS RAs and some aural alerts are inhibited below certain radio altitudes. Radio altitudes and the associated RA status are as follows:
TCAS RA Inhibits (Limits)
ADVISORY OR MODE LIMITS
Increase Descent RA Prevented below 1,550 feet AGL during a climb and 1,450 feet AGL during a descent.
Descend RA Prevented below 1,000 feet AGL during a descent and 1,200 feet AGL during a climb. Resolution Advisories (RAs)
Prevented below 1,100 feet AGL during a climb and 900 feet AGL during a descent (TCAS automatically changes to the TA or TA ONLY mode).
Self-Test
The TCAS self-test is initiated from the ATC/TCAS control page by pushing the TEST line select key, or selecting TEST in the MFD/TCAS tuning window. The following indications should be displayed during the test:
.
TCAS TEST is presented on the TCAS mode line of the PFD/MFD navigation display.
.
Each PFD displays flashing red TRAFFIC right of the heading and vertical traffic resolution cue on the VSI (red/green).
.
TCAS format traffic display shows the TCAS self-test pictorial representation. The display shows four intruder symbols.

GLOBAL POSITIONING SYSTEM (GPS)
Description
The GPS is a space-based navigation system that provides highly accurate three-dimensional position, velocity and time information to ground or aircraft receivers.
The GPS is a sensor used by the flight management system to compute an accurate position. All GPS data is accessed through the FMS CDU.
The GPS has three main segments:
