1.7
ACAS/TCAS Phraseology
1.7.1
ACAS/TCAS equipment reacts to transponders of other aircraft in the vicinity to
determine whether or not there is a potential confliction. The warning (Traffic
Advisory), based on the time to an assumed collision enables the pilot to identify the
conflicting traffic, and if necessary, take avoiding action (Resolution Advisory). In the
UK, this equipment is mainly referred to as ‘TCAS’, however, the use of ‘ACAS’ is an
acceptable alternative in phraseology terms.
1.7.2
Pilots should report TCAS manoeuvres.
1.7.3
The pilot should report when returning to the assigned clearance or when the
assigned clearance has been resumed.
(Controllers may issue a revised clearance at this point.)
1.7.4
Pilots should report that they are unable to comply with a clearance as a result of a
TCAS alert.
In these circumstances the pilot should report when clear of the TCAS conflict.
1.7.5
The pilot should report a TCAS manoeuvre even if it was not possible to notify the
controller that a resolution advisory had occured.
1.8
Communications and Loss of Communications
When a controller suspects that an aircraft is able to receive but not transmit
messages, the radar may be used to confirm that the pilot has received instructions.
When further instructions are given they should be passed slowly, clearly and be
repeated.
