Please confirm or dismiss this theory of mine.............I live right on the flightpath out of BRU about 20km from the airport. Sometimes when I see an Avro climbing out, I swear that I can hear the flaps going up as there is a sudden sound of rushing air. Is it my imagination or are the avro's wings really that loud?
I never think of the future - it comes soon enough.

Your not losing your mind. A/C even makes an announcement inflight about the noise with flaps down on their 146's. I think it is the airflow your hearing and not the flaps moving. At least that is how I understand it when I last flew on a 146.
Sometimes all you can do is look them in the eye and ask " how much did your mom drink when she was pregnant with you?"

The "flap howl" happens when the flaps are in transit between 0 and 18 degrees going either up or down. Its most prevalent at about 200 knots. And yes, when on the ground you will hear the "flap howl" more than you will hear the engines.

When MM had 9 ARJ100 flying here in Colombia it was very easy to identify the airplanes overflying the city of BOG during take-off on departure and approaching to land with flaps down due to the particular noise the flap howl made.

I was on a ARJ85 flight last year from MBS to DTW when right after we took off an older couple sitting behind me heard that noise and the guy said to his wife that it is a normal thing to shut 2 engines down to save fuel and that was the noise they heard....I laughed so hard when I heard that but I was never kind enough to tell them different...

Hammer, that's a classic urban legend. I've heard the same for the 747. FUNNY!
VS346, go to Stockholm and fly from Bromma. Avro Central since Malmö Aviation only flies the BAe-146/Avro RJ. And Stockholm is worth a visit all on it's own. Go from late May to July for the best weather.
Lovely approach and/or departure too, over the city.
Finally, Malmö Aviation have allowed me to jumpseat after 9/11. The captain said they didn't really see themselves as a hijacking target. In fact, in late 2001, I went up to the cockpit after landing and had a chat. The captain asked: "Why didn't you come up in flight? You could have jumpseated." ARGH!

I used to be a F/A on the 146-300 for Air NZ, and during training we were never warned of it, and surprisingly, I don't ever remember any pax asking what the noise was. I asked one of the Captains one day, and apparently the official name for the noise is either "flap toot" or "flap hoot"...I can't remember which it was but sounds comical anyway!

2 weeks ago I flew an Avro 100 of SNBA from BRU to FCO.
The flaps when they are going in or coming out before landing they really have a strange noise which is completely different than the other a/c's.
It sound as if there is a kind of vacum pressure while the flaps are moving....

Is this something that is heard all times the flaps change? I flew one MSP-GFK two weeks ago, the pilots said I would hear it. After takeoff, I felt the flaps retract, and on landing, I felt them go out. I was in front of wings so that could have attributed to it.
