Correct. WIND SHEAR...WIND SHEAR.

Ground Proximity Warning System is Whoop Whoop, pull up.

Nope. It's the otto-pilot being disengaged. Heard it today on the 319. Same system tones as the RJ.
I sat in many (empty) RJs during FlyI's first few months and rode in the cockpit.
Also, since my j/s backed up to the cockpit and I would hear that chirp, I very soon after that asked what it was.

One FlyI flight sticks out...I was the f/a on a FlyI RJ, and while landing into IAD at about 6:30 a.m., I heard the sytem call out 'TRAFFIC...TRAFFIC', and we pulled up and to the left. At the same time, a helicopter buzzed us. Turns out it was the Fox5 news chopper off to cover the very important closure of RT28 due to a dump truck that spilled dirt on the freeway. If our captain hadn't turned as he had, Fox5 would have been making it's own news! (not that they don't already). The go around took another 1/2 hour to complete. Jerkz!!!

What type of airspace were you in? Most likely they were VFR so it is see-and-avoid unless it was Class B airspace. In that case, it is the controllers responsibility....although the controller will get to go home that night


BTW, the person who posted about the marker beacons reminded me of when I was a PPL only (now IA). I was flying back near Santa Cruz, CA on a quiet, very calm evening with the sun setting over the Pacific when myself and my 3 passengers heard beep beep beep, beep beep beep. I started trouble shooting..... AP wasn't on, definitely not the transponder, definitely not the comms, I was using GPS and that wasn't doing it. Hmmmm, a few seconds later the beeping is gone. Turns out it just happened that the SNS ILS was tuned in, just happened the marker beacons were on (on high nonetheless) and just happened I was perfectly on course. It scared the hell out of my passengers even after I told them it was nothing. A packet of peanuts, a FULL can of coke and they were smiling again. ;-)

Forgot we were on final coming into IAD at that hour and had to to a g/a because of it. Pretty scary. Turns out, the crew didn't even see the helicopter. I noticed it out of my porthole on the galley door. But the heard the alert. Damn hot shot news copter jockeys!

I'm guessing it was Class B in which case the controllers didn't separate the a/c properly or someone wasn't following their clearance and the controller didn't see it. Or it could have been the news helicopter was below the Class B. Just guessing on my behalf. Nonetheless, in visual conditions it is still see-and-avoid. Airplane vs. helicopter means the helicopter has the right of way.

My (former) CFI/CFII told me once he got chewed out on frequency for a similar encounter with a WN jet. He then told the controller he was in visual conditions, in Class E airspace and he was on flight following (radar contact, etc.) so no one did anything wrong at all. See and avoid (plus TCAS).

But wouldn't there be certain restrictions about flying a copter directly into or near the flight path of an oncoming a/c. Wouldn't the a/c have the right of way (sorry...just using logic, which most times doesn't come into play in the airline world).

That's not the exciting one. "TRAFFIC, TRAFFIC" is a pretty common TCAS advisory in busy airspace. A TCAS resolution alert "CLIMB, CLIMB NOW" will get your attention! Manuevering in response to a "traffic" advisory isn't normally required. But you'd better put some gentle Gs on the plane if you get a resolution alert.

Another couple that will get your attention...
"Sink Rate", "Sink Rate". and "Terrain"', "Terrain".
I got to hear those alot when I tried to fly the 777 and 747-400 at
UA's training facility in Denver. (I had a friend who worked on the computer
software than ran the sim's. She would bring us in at least twice a month on the weekends to fly, that was pre 9/11. She doesn't work there anymore and I think I heard they opened it up to friends of employees again)

deleted - woops - ExCrew covered it perfectly in post 32, and I missed it.

the helicopter has the right of way since the fixed-wing airplane is more manuevable. Heli have the right of way over airships. A/c who declare an emergency have right of way over everything.

In visual conditions, regardless of being IFR or VFR, it is the responsibility of ALL pilots to see-and-avoid other aircraft. in Class E airspace below 10000 MSL there could be a Piper cub without an electrical system cruising along at 85 KIAS with no transponder. That 744 on an IFR flight plan might be descending. Everyone is 100% completely legal considering the airspace, altitudes, VMC, etc. The 744 won't get any TCAS alert or RA since the Cub doesn't have a transponder (note, I fly bugsmashers myself so maybe larger jets can pick up other a/c on other systems). Further, say the radar is down in the area for maintenance, the ONLY way to avoid a collision is see-and-avoid. Fortunately there is lots of air above the ground. In the US there's about 8 mid-airs each year. Not too bad considering there are 10000 commericial a/c and about 250000 general aviation aircraft. Those commercial jets are only a tiny subset of aviation despite what people think.

Note, in Instrument Conditions (IMC) or in Class A airspace where all A/C have to be on IFR flight plans, ATC has the responsibility of a/c separation. In this regard, flying in IMC is easier as there is nothing see outside.

It most certainly is part of the audible warning.
