While we were flying the river visual to Runway 19 into DCA we received a TCAS alert. We were around SETOC or just past it and fully configured to land. There was, what I could only guess as I never saw it, a helicopter about 300ft below us…………… Suggestion: Need to have better separation for DCA traffic on the river visual to the helicopter traffic that is flying up and down the river.

2.

ATC delayed switch from Approach to Tower led to TA and resulting altitude deviation causing a GPWS Caution. Tower then issued a low altitude alert. Helicopter traffic was heading up the Potomac while we were on the river visual approach……… did not alert us to the on coming traffic . By the time Tower responded we had a RA to descend which led to a GPWS and low altitude alert from Tower.

Our flight] into DCA was in a NMAC. We were supposed to circle from the visual Runway 1 to instead land on 33. We followed the [company] station bulletin procedures exactly as planned and came within very close contact of another aircraft. This occurred about 400 feet off the ground to the point where the pilot monitoring had to take the controls to make a correction in order to prevent it from becoming a midair collision……….

…………Otherwise the other reason this may have happened is because of an unclear idea of where aircraft should be located during Runway 33 circle to land operations. I believe I was on track with what the [company] guidelines are for that particular procedure but there is a possibility that the other traffic operating around that area may not be aware of where exactly we are located or maybe they don't have a specific guideline to keep the arriving traffic separated from the low flying helicopters.

…………..I understand DCA is a busy airport, I was based there for years. The military low level helicopter traffic that routinely is in the DCA traffic area complicates matters. But this is probably the most dangerous airport in the United States, strictly based on the the fact the controllers are pushing, pushing, pushing, in an attempt to handle the traffic they have.

We were cleared to circle to and land on runway 33. ATC also added that there was a low level helicopter and that the helicopter had us in sight. At the Wilson bridge we turned to the northeast to set ourselves up for a landing on runway 33. We continued normally and started our turn to final when I saw an opposite direction helicopter very close to our altitude, but slightly below us and climbing . I was about to initiate the go around regardless of the TCAS when we got the RA. As we started the go around I saw thehelicopter make an aggressive descent.

The tower supervisor I spoke with told me a few things that explained what may have
happened. Number one, he said that the helicopters operating in that area should NEVER be above 200 feet……..He suggested that it was most probably a deviation on the part of the Pilot of the helicopter, and a loss of aircraft separation that was also the fault of the helicopter pilot.

It was the end of a long day and the events were happening very quickly during a high workload portion of the flight. As all pilots know, the River Visual is a very demanding approach during the best of circumstances………..The radio chatter was considerable and the Tower at some point advised us of helicopter traffic ahead and to the left (I believe he said 10 to 11 o'clock ) and he was going to pass from left to right, below us and he "HAS US IN SIGHT." It has to be noted that these traffic calls and helicopters have unfortunately become background noise. There are always numerous military and government helicopters running up and down that river at all times of the day and night. Because of this, what would normally be alarming at any other airport in the country has become commonplace at DCA. The FAA allows these aircraft to operate in this environment and we have no choice, but to accept it and deal with it. Therefore, the helicopters being very close are not out of the norm……..
……….As I was approaching 4 DME , I caught a glimpse of the helicopter out of my left window and he did look higher than I expected to see him. I asked the First Officer to confirm if he was going to cross from north to south. He confirmed, however I directed him to ask the Tower and confirm it with them because it did not look right. The First Officer could not get a word in with the Tower. It was at that point, we got a TCAS "TRAFFIC" call. Again, this is not out of the 'norm' for DCA………… .The helicopter passed 200 FT (MAX) below us. The Tower never called out the traffic beyond the first notification……… .
………. Due to the workload, we asked the Ground Controller for the Tower number and I called when I got to my vehicle. I called the Tower and spoke with the Controller in charge. After some prodding, he admitted that it was a military helicopter flying from/to Ft. Meade and that he was at 700 FT and was "a little higher than normal." I asked what altitude was he supposed to be at and he replied, "three to four hundred feet. "………… … I cannot imagine what business is so pressing that these helicopter s are allowed to cross the path of airliners carrying hundreds of people!

We were on the Mount Vernon Visual Approach to Washington National Airport, and the Tower instructed us to circle to land on Runway 33. While we made our approach to Runway 33, Tower advised a helicopter was maneuvering at our 12 o'clock position. As we continued our approach, Tower instructed the helicopter to "make a right 360 for a jet on a 2 mile final for Runway 33, and to report him in sight" (referring to our aircraft.)

The Tower then asked the helicopter if he had us in sight. He replied "yes", and the Tower told him to maintain visual separation. As we began our turn from base to final, the helicopter made what looked like a right turn directly into our flight path. The Captain, the pilot flying, made a hard right turn and executed a missed approach to avoid a collision.

WE WERE EXECUTING AN ILS IN IMC. AS MY FO ANNOUNCED 'APCHING MINIMUMS, RWY IN SIGHT,' I BEGAN MY TRANSITION FROM FLT DIRECTOR REF TO VISUAL REF FOR A HAND FLOWN LNDG. MY AIRSPD WAS PROBABLY AROUND 130-135 KIAS. AS I WAS TRANSITIONING I SUDDENLY SAW A DARK COLORED MIL HELI ON MY APCH PATH. HE BLENDED IN VISUALLY WITH THE DISMAL WX CONDITIONS. I DID NOT NOTICE ANY ACFT LIGHTING. AS I SAW HIM, SO DID THE DCA TWR CTLR. THE CTLR……….. HE SAID THAT THE PHONE CONVERSATION REVEALED THAT EXTENSIVE TRAINING FOR A MIL EXERCISE WAS TAKING PLACE ………THE RPTR DOESN'T KNOW WHETHER THE HELI PLT MISUNDERSTOOD HIS INSTRUCTIONS OR WHETHER THE CTLR ISSUED SUCH INSTRUCTIONS IN THE FIRST PLACE.

WE WERE ON THE RIVER VISUAL APCH TO RWY 18 AT DCA. THERE WAS A MIL HELI OPERATING A TRAINING FLT FLYING N TO S OVER THE RIVER AT 500 FT MSL…… TWR ADVISED US OF THE HELI AND THAT HE HAD US IN SIGHT AND HE WOULD MAINTAIN VISUAL SEPARATION WITH US . WE OVERTOOK ALMOST DIRECTLY ABOVE THE HELI AT ABOUT 3.5 DME AND 1100 FT MSL, RIGHT AT THE TURN IN THE RIVER THAT IS REQUIRED ON THE APCH. WE RECEIVED AN RA FROM OUR TCASII AT 1100 FT. WE FLEW AS FAR TO THE E SIDE OF THE RIVER AS WE COULD TO MAINTAIN VISUAL ON THE HELI ON THE W SIDE OF THE RIVER…….
……..AFTER LNDG, I CALLED THE TWR SUPVR AND HE LISTENED AND SAID THIS WAS NORMAL . I HAVE FLOWN THIS APCH AT LEAST 15 TIMES AND I AM VERY FAMILIAR WITH THIS APCH. HOWEVER, I CONSIDERED THIS APCH PUSHING THE ENVELOPE FOR SAFETY, WITH THE AMOUNT OF ATTN I HAD TO GIVE TO THE HELI WHILE FOLLOWING THE RIVER AND DSNDING IN A XWIND AND AT A HIGH LNDG WT. …………. I'M SENDING IN THIS RPT BECAUSE I WAS NOT COMFORTABLE WITH THE LEVEL OF SAFETY INVOLVED WITH FLYING WITHIN 400 FT VERTLY OF A HELI AND THAT IS CONSIDERED A NORMAL OP.

DURING ILS APCH, SBOUND, HELI COMING DOWN POTOMAC RIVER ABOUT 500 FT MSL, TFC CALLED BY TWR, WE DIDN'T SEE IT. WE GOT AN RA ON TCASII -- HAD TO FOLLOW RA INSTRUCTIONS…….. THIS HELI CONFLICT AROUND DCA IS A DAILY PROB! GOING TO TA ONLY ON TCASII WOULD DEFEAT PURPOSE OF TCASII. LNDG ACFT SHOULD NOT HAVE TO ACCOMMODATE HELI'S. THIS IS AN ACCIDENT WAITING TO HAPPEN.

I WAS TURNING FINAL FOR STOL LNDG RWY 21 DCA. I SAW A HELI APCHING ON CONFLICTING FLT PATH. IT WAS APPROX 400 FT BELOW US, BUT WE WERE DSNDING FOR LNDG. I ADVISED DCA TWR OF TFC. HE SAID 'TFC LOW LEVEL, 200 FT.' JUST AS I WAS GOING TO MANEUVER TO AVOID, THE CHOPPER MADE A STEEP TURN AWAY FROM US. AT THIS POINT WE WERE WITHIN 100 FT VERTICALLY AND 1000 FT HORIZLY………. I HAD NO WAY OF KNOWING IF CHOPPER PLT HAD US IN SIGHT (UNTIL HE MADE THE EVASIVE TURN). THIS IS BY NO MEANS THE FIRST TIME OF SUCH AN OCCURRENCE AT DCA. I HAVE HAD MANY CONFLICTS WITH CHOPPERS, BOTH ON LNDG AND TKOF AT DCA. I HAVE TALKED TO TWR SEVERAL TIMES (INCLUDING THIS TIME) AND HAVE RECEIVED APOLOGIES AND ADMITTING OF ERRORS BUT THE PROB CONTINUES.

DURING RIVER VISUAL APCH DCA (LNDG RWY 18), 3 HELIS CROSSED OUR FLT PATH. THE FIRST CAUSED AN RA ON TCASII WITH A 0-300 FT CLB (WHICH WE FOLLOWED). THE HELI WENT DIRECTLY UNDER OUR ACFT WITH LESS THAN 300 FT SEPARATION. WITHOUT THE RA WE WOULD HAVE COME EVEN CLOSER THAN 300 FT TO THE FIRST HELI.

WASHINGTON APCH CTL CLRED ACR X FOR THE MT. VERNON 36 APCH. AT THE WILSON BRIDGE THE TWR CLRED US TO LAND STOL ON RWY 33. I TURNED OFF THE MT. VERNON 36 APCH ONTO A L BASE LEG FOR RWY 33. THE PATTERN FLOWN WAS SQUARE. I TURNED FINAL ABOUT 1/2 MI S OF THE E BANK OF THE POTOMAC RIVER…………..LINED UP ON FINAL AND STABILIZED FOR A STOL LNDG, I SUDDENLY CAUGHT SIGHT OF A PRESIDENTIAL TYPE HELI XING OUR FLT PATH, APPROX 50-100 FT BELOW AND 100 FT IN FRONT OF US AT OUR 11:30 POS, AS WE PASSED THROUGH 600 FT MSL . THE HELI WAS MOVING L TO R AT A GOOD SPD, BUT I DETERMINED A COLLISION WAS POSSIBLE AND IMMEDIATELY APPLIED PWR, PULLED UP AND CALLED 'GAR' TO THE FO. AS WE PULLED UP I CALLED OUT THE HELI TO THE FO WHO THEN SAW IT CLOSE AND BELOW AS IT PASSED OFF THE R SIDE. THE HELI IN QUESTION DID NOT APPEAR TO ALTER COURSE OR FLT PATH UNTIL DSNDING AND LNDG AT ANACOSTRA………….
…………I WAS NEVER ABLE TO DETERMINE IF THE TWR KNEW OF OR HAD TALKED TO THE HELI IN QUESTION. MANY TIMES THE TWR TALKS TO HELIS ON A DIFFERENT FREQ, BUT YOU CAN HEAR THE TWR'S COM TO THEM ON 119.1. THEY WILL USUALLY POINT OUT HELI TFC TO US AND COMMENT THAT THE HELI IS AT SUCH AND SUCH AN ALT, DIRECTION AND THAT THEY (THE HELI) HAVE US IN SIGHT . THIS INCIDENT WAS 'VERY' CLOSE AND FAR FROM THE NORM I'VE EXPERIENCED IN 15 YRS OF FLYING INTO AND OUT OF DCA.

HOT, HAZY AFTERNOON IN WASHINGTON (HAZE DID RESTRICT VISIBILITY) FLYING THE RIVER VISUAL APCH TO RWY 18 AT DCA, CREW IS DCA BASED SO WE ARE VERY FAMILIAR WITH THIS APCH. AT ABOUT 4-5 DME, TWR ASKED US IF WE COULD LAND ON RWY 15, I DECLINED AND SAID THAT I'D LIKE TO CONTINUE FOR RWY 18. TWR THEN ADVISED US THERE WOULD BE 2 HELIS COMING OUT OF THE TIDAL BASIN AREA. (IT IS NOT AT ALL UNCOMMON TO SEE HELIS XING OUR FLT PATH WHEN WE ARE TAKING OFF TO THE N AND CLBING). I COULD SEE A CONTACT ON OUR TCASII SCREEN -- JUST ONE TARGET -- AND BTWN 600 AND 500 FT ON FINAL, WE GOT AN RA THAT COMMANDED CLB. I HAD THE FO LEVEL OFF AT 500 FT, THE TARGET SHOWED 200 FT BELOW ON THE TCASII AND VERY CLOSE ABEAM ME ( ON 5 NM SCALE) AND I NEVER DID SEE EITHER HELI………
…………I HAVE BEEN FLYING THIS APCH AT DCA FOR 7 1/2 YRS, AND THIS ONE REALLY GOT MY ATTN. TWR IS NOT CTLING THE HELIS, I CAN'T BE SURE THE HELIS HAVE ME IN SIGHT ……………….I KNOW THE SECOND HELI IS LOOKING AT HIS LEAD …… THIS HAD THE POTENTIAL TO BE A MIDAIR, AND UNFORTUNATELY, PROBABLY IS CONSIDERED ROUTINE OPS BY DCA TWR.

MANEUVERING IN GOOD VMC FOR LNDG ON RWY 21 AT DCA (CLRED FOR VIS APCH, MONITORING TWR FREQ FOR LNDG CLRNC). TWR ADVISED OF HELI TFC BELOW AND AHEAD. THIS TFC WAS SPOTTED FLYING SW WHERE ANACOSTIA RIVER MEETS POTOMAC. NO CONFLICT, INITIALLY. THE HELI, A MIL TYPE, THEN TURNED NW UP THE POTOMAC RIVER. THIS NOW BECAME AN IMMEDIATELY INCREASING TFC CONFLICT. CONVERGING FLT PATHS. I ASKED TWR TO PROVIDE SEP, HOPING HE WOULD STOP, SLOW OR TURN THE HELI. HE RESPONDED WITH, "MAINTAIN VIS SEP." MANEUVERING IN CLOSE FOR A STOL LNDG ALLOWS FOR VERY LITTLE LEEWAY FROM THE DESIRED FLT PATH……..

……….. THERE WAS NO TIME TO COMMUNICATE THIS TO TWR AND THE HELI WAS ON A DIFFERENT FREQ . I CONTINUED AND LANDED VERY CAUTIOUSLY WHEN I REALIZED WE WOULD MISS TFC. HOWEVER, WE ONLY MISSED BY APPROX 300'. I FEEL THAT ATC (TWR) IGNORED ITS BASIC OBLIGATION OF PROVIDING SEP. THE HELI COULD HAVE EASILY BEEN SLOWED, STOPPED OR TURNED AS A MEANS OF AVOIDING AN IMPENDING COLLISION . TWR CERTAINLY WOULD HAVE BEEN AWARE OF BOTH ACFT'S FLT PATHS. I HOPE THEY (TWR) DO NOT THINK 200-300' IS A SAFE AMOUNT OF TFC SEP. THIS HELI CONFLICT, AND POOR ATC SEP OF IT, AT DCA IS AN ONGOING PROB. HERE IS AN ACCIDENT WAITING TO HAPPEN.
