The first maneuver of intruders is computed to allow them to always respect a relative
altitude of 100 to 150 feet inside the RA altitude envelope. As soon as one of the two
intruders meets both TA conditions (i.e. altitude and range), the audio message
“TRAFFIC TRAFFIC” is heard.
The intruders should stabilize at an altitude inside the RA altitude envelope and
maintain a level flight until the end of the scenario. During this scenario, TCAS will
give preventive advisory like “MONITOR VERTICAL SPEED” when the first
intruder satisfies both RA conditions (i.e. altitude and range). No corrective advisory
should be heard until the “CLEAR OF CONFLICT” message is issued and no crew
action is required for this scenario.
16.4.1.1.3.3 Resolution Advisory (Single Threat) Climb/Descend
Scenario specifics:
•
TCAS generates an RA requiring the crew to climb or descend to avoid conflict.
•
Number of intruders specified in this scenario is 1.
•
Own aircraft V/S recommended max limit +/-1000 fpm.
In this scenario, the intruder starts from the direction selected on the Horizontal
Position pane and remains at the same altitude until the time of collision is
approximately 100 sec before the closest point of approach.
The first maneuver of the intruder is computed to allow the intruder to reach a relative
altitude within the RA altitude envelope (which is approximately 100 ft inside the
envelope) and 10 seconds before the intruder enters into the RA range envelope.
During this maneuver, the audio message “TRAFFIC, TRAFFIC” should be heard
initially when the intruder satisfies both TA conditions (i.e. altitude and range).
In the next 15 seconds, the vertical path of the intruder is computed to target an
altitude of 100 feet above (or below) the own aircraft altitude at the closest point of
approach.
During this phase, a corrective advisory message should be issued to avoid the
intruder. The crew must follow the corrective advisory rapidly and smoothly without
overshooting the target. The intruder will continue his descent (or climb) at a rate
between 1500 and 2000 feet/minute until 5 seconds after the closest point of approach
and stabilize at this altitude. No other corrective advisory message will be announced
until the “CLEAR OF CONFLICT” message.
