Many TCAS TA and RA on KDCA ARRIVAL and FINAL APPROACH, but NO INTRUDER TRAFFIC AROUND

The Federal Aviation
Administration is investigating a multitude of Traffic Collision Avoidance
System (TCAS) alerts near Reagan National Airport in Washington. Multiple
aircraft from different air carriers reported the alerts Saturday while on the
River Visual approach.
Despite these alerts, no other aircraft were detected nearby.
Many aircraft received resolution advisories (RAs), directing the crew to
maneuver away from a potential collision.
“Several flight crews inbound to Reagan Washington National
Airport received onboard alerts Saturday indicating another aircraft was nearby
when no other aircraft were in the area. Some of the crews executed go-arounds
as a result of the alerts,” an agency spokesperson said in a statement. “The
FAA is investigating why the alerts occurred.”
One Republic Airways
crew reported an RA at around 1,200 feet, adding that “there was something
diving straight onto us,” per air traffic control audio recordings.
Another PSA Airlines crew said they got two traffic advisories (TA), which warn
of a non-imminent collision.
