Can anyone shed some light on A300 take off certifications for no flap take offs...does this exist? I just viewed an image shot by a passenger of a A300 shot over the wing shortly after rotation and the flaps are clean...does appear to have leading edge slats extended that I can tell but no flaps?

Thanks for the replies...all the A300 departures I have shot...all the trips I have had on A300...never seen a clean wing take off, excepting slats...I was very surprised to see this image...was on "the other" site.

Quoting Eaa3 (Reply 3): But do airlines really do it given that it would cause passengers worry?
I got that fright once flying SAA when they still had A300s, turned onto the runway and hit the gas with no flaps, I went ice cold inside but of course the flight went off without incident. It is quite unnerving if you are used to the sounds and sights pre-takeoff.
After Monday and Tuesday even the calendar says WTF...

Yep, the purpose of a "0" Flap takeoff, at least on the plane I fly and I am sure the A300 for the most part as well, is to better meet the 2nd segment climb restrictions in the event you lose an engine.
A two-engine jet must be able to climb at 2.4% climb gradient on 1 engine in the 2nd segment which is the altitude of gear retraction to in my case, 1500' agl. With no flaps for takeoff, you need to rotate at a faster speed, thus using more runway, but you will have the speed in the case you lose an engine to be able to climb at your minimum climb gradient. It's a little more complicated than that because it's mostly a weight issue, but it is perfectly safe and normal in planes it is approved on.
I normally only have to use it when it starts getting warmer out at higher altitude airports at heavy weights. We rarely, if ever, have to do them at sea level airports but we can if we need/want to. I wish I had my takeoff numbers here at home to get specific weights and numbers for some good examples, I'll try and dig some up.

LOL, I knew the a300 would take off with no flaps when I first flew it last week, and I still found it unnerving to see! Take off was like a rocket though...
Thats what I thought when the captain of our "KIWI" 727/200 announced we were next for the active runway and instructed the crew to take their seats, just as a Vanguard 727/200 was rolling down the runway for take off. I couldn't help but notice that the wings were still clean...like in 31,000 feet cruise clean!...I jumped out of my seat and walked briskly back to the two seated flight attendents already in their jump seat. Ignoring their commands to immedietely be seated, I leaned over and informed the male FA that the wings were not configured for take off...she (the female) FA kept yelling at me...the male FA grabbed the service phone to call the front office and what was music to my ears was the sound of those terrific noisy flap motors setting out flaps, not one notch, but two notches for take off. Later during the flight the male FA visually acknowledged and thanked me for my vigilence while the female of the species continued to lambaste me and reminded me that the crew in the cockpit had more than 30 years of experience...I then reminded her...so did the crew of the NW DC-9 that took off clean and killed everyone in Detroit, I also reminded her that circuit breakers exist and pilots dissable annoying audible warnings...True story...

I have done it on an AA 767 out of MAN to ORD, this not long after the Detroit accident. Not only was it flapless, but we did a downwind take off. Everything else was heading for what was the )^ but we headed for 24. I was sat near the rear of the a/c and only noticed the lack of flaps as we turned on to 24 and started to roll. We did a long roll but when we rotated, boy did we climb. Found out later is was because we were well loaded and because of the design of the 24/06 runway, you can claim more distance due to safety overrun at the 06 end and it gave us a better climb out margin in the event of an engine failure. Had me worried for a short while, but I did have my faith in those 767 drivers, and all went well for the rest of the flight. Did many a trip on the AA55/56 in those years 1987-1990 but this was the only flapless t/o I was ever on.
Was that a 200 series or 3?...I've flown a lot on transport aircraft, with the exception of my above KIWI experience, never had clean wings on take off. Another exception is the F-100 and 28...just figured that was normal for them as I do see that quite often.
I honestly cannot remember if it was a 2 or 3 series, I cannot remember when they changed, maybe the AA members could put us right. I understand it was not a total clean wing ala F28 as slats would have been selected, obviously from where I sat, I could not see them on the B767

The 170 will do take offs at flaps 1 as well. In this configuration the slats are extended but the flaps are not. It's used at high/hot airports for second segment climb. In a year of flying that plane I've only done it twice out of DEN on really hot days.
: I flew the route between 1985 and 1996 (1987 to 1990 on a monthly basis) and it was always a B767, never ever saw the AA MD11 at MAN
: Really? You would know better than me, but I have sat in the back of a 50 seat CRJ literally hundreds (if not thousands) of times commuting and have
: I flew a CO A300B4 once in 1994 and there was very, very minimal flap extension which freaked me out but we of course took off no problem.
