16.4.1.1.3.5 Resolution Advisory (Dual Threat) Climb/Descent then Level
Off
Scenario specifics:
•
TCAS generates an RA requiring the crew to climb or descend to avoid conflict.
•
Number of intruders specified in this scenario is 2.
•
Own aircraft V/S recommended max limit +/-1000 fpm.
During the maneuver, the crew is required to do a second maneuver to clear the
conflict, due to the maneuver by the second threat.
Two intruders will be asymmetrically positioned (in horizontal and vertical planes)
with respect to own aircraft. Only one of the two intruders will start from the
direction selected on the Horizontal Position pane while the other intruder will be
positioned at a relative bearing which varies from 15 to 45 degrees from the bearing
of the first intruder.
Each intruder remains at the same altitude until the time of collision is approximately
100 seconds before the closest point of approach. One of the intruders will pass above
and the other intruder will pass below the own aircraft during the scenario.
The maneuver of the first intruder is computed to allow the intruder to reach a relative
altitude inside the RA altitude envelope (about 100-150 feet inside) and 10 seconds
before the intruder enters into the RA range envelope. During this maneuver the audio
message “TRAFFIC TRAFFIC” should be heard when the intruder meets both TA
conditions (altitude and range).
During the next 15 seconds, the intruder vertical path is computed to target an altitude
100 feet above (or below) the own aircraft altitude at the closest point of approach.
During this next phase, a corrective advisory message should be issued to avoid this
intruder and will command the crew to fly the aircraft in the direction of the second
intruder.
The crew must follow the corrective advisory rapidly and smoothly without
overshooting the target. The first intruder stabilizes at this altitude and the second
intruder, who was not previously a resolution advisory, becomes a resolution
advisory.
A second corrective advisory message, “LEVEL OFF, LEVEL OFF”, should be
issued to avoid the second intruder. The crew must follow the corrective advisory
rapidly and smoothly without overshooting the target. No other corrective advisory
message will be announced until the “Clear of conflict”.
