The Federal Aviation Administration (FAA) is conducting an assessment of enhanced Final Approach Runway Occupancy Signal (eFAROS), part of the Runway Status Lights System (RWSL), at Dallas Fort/Worth International Airport (DFW) in Dallas, Texas. The operational evaluation of eFAROS at DFW commenced in September, 2011, and is continuing indefinitely. eFAROS has been installed at DFW to reduce the frequency and severity of runway incursions. At DFW, eFAROS flashes the existing Precision Approach Path Indicator (PAPI) lights to directly indicate to pilots on final approach that the runway is occupied and may be unsafe for landing.

eFAROS is an experimental system autonomously driven by safety logic based on aircraft location from airport surveillance radars (ASRs), surface detection radars (ASDE-3 or ASDE-X), and multilateration information from the ASDE-X surveillance system. The FAA expects eFAROS to prevent the occurrence of both runway land-over incidents and occupied runway accidents. eFAROS provides a signal of runway occupancy directly to pilots, per NTSB recommendation.

The FAA's assessment of eFAROS at DFW will be conducted on runways: 18R/36L and 18L/36R on the West airfield, 17R/35L and 17C/35C on the East airfield. The existing PAPI lights have been modified to flash if runways 18R/36L, 18L/36R, 17R/35L, and 17C/35C are occupied and/or there is a potential conflict for the arriving traffic.

Pilot Protocol for eFAROS

When eFAROS acquisition point of 500 ft AGL is reached with flashing PAPIs

  • Attempt to see traffic on runway
  • If seen, evaluate the situation then proceed with caution
  • If not seen, prepare to contact ATC at contact point

When eFAROS contact point of 300 ft AGL is reached with flashing PAPIs

  • Attempt to see traffic on runway
  • If seen, evaluate the situation then proceed with caution
  • If not seen, contact ATC to verify landing clearance and prepare for an immediate go-around

If ATC does not verify landing clearance promptly, go around
If ATC cancels the landing clearance, go around

A STEADY PAPI SIGNAL DOES NOT CONSTITUTE CLEARANCE TO LAND!
