Flight Test Scenarios

During a nighttime flight test in June 2014,  the following 13 scenarios were flown at BOS to assess the effectiveness and safety of eFAROS for daily operational use.  The video and audio recording of each scenario is provided in the links presented here.  Please select a link to view or download any individual scenario.  The procedures used and objectives tested are documented in this list.


Scenario 1
 eFAROS Activation on Rwy 4R with Aircraft or Vehicle Taxiing Along Rwy:  eFAROS activates for an aircraft taxiing or a vehicle moving along a Rwy in the same direction as an arriving aircraft.


Scenario 2
eFAROS Activation on Rwy 27 with Aircraft or Vehicle Moving in Opposite Direction on Rwy:  eFAROS activates for an aircraft or vehicle moving in opposite direction on the Rwy.


Scenario 3
eFAROS Activation on Rwy 22R with Aircraft or Vehicle Crossing on Rwy:  eFAROS activates for an aircraft or vehicle crossing the Rwy.


Scenario 4
 eFAROS Activation on Rwy 22L with Aircraft or Vehicle Stopped on Rwy:  eFAROS activates for an aircraft or vehicle stopped on the Rwy.


Scenario 5
eFAROS Activation on Rwy 33L with Vehicle Simulating Aircraft In-Trail Arrival on Rwy:  eFAROS activates for an arrival when a previously landed aircraft (simulated by vehicle) is still on the Rwy and moving


Scenario 6
eFAROS non-Activation on Rwy 4L with Rwy 4L in LAHSO for Rwy 15L/33R:  eFAROS does not activate for arrival when a Rwy is occupied beyond the LAHSO line.


Scenario 7
eFAROS Activation on Rwy 4R with Aircraft (simulated by vehicle) for Arrival-Departure Tail Chase:  eFAROS activates for arrival when a departing aircraft (simulated by vehicle) is still on the Rwy and not airborne.


Scenario 8
eFAROS Activation on Rwy 32 with Vehicle on the Rwy:  eFAROS activates for an aircraft or vehicle on the Rwy.


Scenario 9
eFAROS Activation on Rwy 15R with Rwy 15R/33l in Rwy 33L Configuration:  eFAROS activates for an arrival when the Rwy is configured for opposite direction operation.


Scenario 10
 eFAROS Activation on Rwy 22L with Aircraft Departing on Rwy 15R:  eFAROS activates on Rwy of intended landing with an aircraft departing on a crossing Rwy.


Scenario 11
eFAROS Activation on Rwy 4R with Aircraft Arriving on Rwy 33L and Crossing Intersection of Rwys 4R and 33L:  eFAROS activates on a Rwy when an arrival on a crossing Rwy taxies through the Rwy intersection.


Scenario 12
No eFAROS Activation with Aircraft on approaches to Rwys 22L and 27 with both Rwys in LAHSO Configuration:  eFAROS will not activate when intersecting Rwys are in LAHSO configuration.


Scenario 13
eFAROS Activation on Rwy 15R with Rwy 15R/33L in Closed Runway Configuration:  eFAROS activates for arrival when Rwy is in closed configuration.
