4 /4 Project 12.2.2 Phased Development Plan
Wake Vortex Decision Support System is built in three iterative phases dealing with the three steps of the SESAR Concept Story Board
TBS (Time Based Separation) step 1 Acquisition and processing of information about position, strength and behavior of
wake vortex in case of significant headwind
WDS (Weather Dependant Separation) step 2 Real time assessment of wake vortex position, strength; and prediction of wake
vortex behavior to allow separation reduction; depending on weather conditions
PWS (Pair Wise Separation) step 3 Demonstration of the system capacity to dynamically deliver separation per aircraft
pairs; requires aircraft characteristics database (generation of wake vortex, sensitivity to wake vortex). Customization to different airports and runways configurations
WVDSS is an enabler for validation of operational conceptWVDSS pragmatic & iterative developmentWVDSS able to optimize runways throughput and reduce delays on different kind of airports as well as to be adapted to several runway configurations

Wake-Vortex Sensors Requirement Recommendations
Thanks to XP0 results, it has been demonstrated that, in high altitudes, wake vortex behavior, being affected only by the wind, is predictable. out of ground effect, wake vortex predictors will be able to compute wake vortex behavior based
on theoretical models.
They need as input an accurate wind speed and direction.
In these areas, no wake vortex monitoring sensor is recommended. On the opposite, close to the ground, where wake vortex behavior is affected
by IGE, sensor-based wake vortex monitoring is mandatory. sensors scanning domain must be large enough to cover both landing & take-off.
the best sensors position is demonstrated to be sideways, few hundred meters upstream from the touch down area.

Wake-Vortex Sensors Recommendations
The main results were convincing in terms of wake vortex detection: Most of wake vortices were detected in both critical areas The detection range has been demonstrated to be over the detection needs. wake vortex was detected as long as it was in the sensor scanning domain, except for some
cases where detection algorithms must be tuned.
Results show that RADAR and LIDAR are complementary depending on weather conditions: X-band RADAR performances are optimal under humid conditions LIDAR performances are optimal in dry air.
Nevertheless, some improvements have to be done on these sensors to reach the performances needed by an operational system: Update rate needed to scan the Wake-Vortex 3D volume should be around 10 s. This capacity is
already available for LIDAR, but should be developed for RADAR by Electronic scanning A gap in data availability has been observed in particular weather conditions, after rain when air
has been cleaned from aerosols. Thus, the RADAR power budget must be increased in order for it to detect wake vortices in the whole domain where LIDAR data are not available.
These development were already planned within the project. Thus, the campaign results confirm the theoretical analysis.

15 /15 UFO Goals
Safety margin of Wake-Vortex Separations are dependent of Wind assessment accuracy
UFO will improve the update rate and the accuracy of Wind assessment: to optimize this Safety Margin to generate Alert in case of abrupt wind changes
UFO will study dedicated Wind sensors compliant with future Airport Weather operations requirements
NOTA : Last ICAO recommendations for Wake-Turbulence hazards mitigation on Airport promote the use of X-band Radar (with Lidar). In ICAO 2012 Working Document for the Aviation System Block Upgrades, THE FRAMEWORK FOR GLOBAL HARMONIZATION, issued 17 JULY 2012 (http://www.icao.int/Meetings/anconf12/Documents/ASBU.en.july%202012.pdf ), we can read in Annexe A on Module N B1-70 (Increased Runway Throughput through Dynamic Wake Turbulence Separation) : This capability will be provided by a combination of X-band radar and Lidar scanner technology. This new standard, readiness is scheduled by ICAO to be applicable as soon as 2018.
