Howdy,
Can anyone tell me if it is possible to have the flap setting to zero for takeoff and under certain conditions, rotate and climb successfully?
Are there any wind strengths and wind directions (I don't mean 300 miles an hour either.) that make this possible and is there any airport in the world due to its elevation or perhaps "unsual" meteioralogical conditions that "could" permit this?
Or.... if they are not set, anything from a DC-9 above, you are toast! period!
Any pilots, mechanics or instructors able to answer this?

It depends entirely on the airplane. If flaps are required for takeoff, and a configuration warning device is enabled, then a warning will sound if flaps are not in correct position. Older airplanes don't have these config warnings. Some aircraft don't need flaps for takeoff.

I have a photo of a PR 744 lined up on the runway at Kai Tak with zero flaps !!!, As soon as he applied power he took it off again, must have been a few warnings going off !!!

There was an accident in the U.S. related to this. There was a DC-9 crashed about a min after takeoff because the pilots forgot to lower the flaps. Need not to say, all died on board.

To be specific, I guess I am referring to western commercial aircraft and Airbus.
ex. Can an A320 accomplish in any safe flying conditions what I wrote?
Red Panda: you are referring to the NW crash in Detroit. One baby survived the crash and lives in an undisclosed location presumably still in the states.

As far as I know, the Fokker F-100 can do a 0-flaps T/O. There was a discussion in the Tech/ops forum a while ago, go do a search there and see if you can find it.

Beech 350s don't require flaps unless the runway is short. Airliner's require them, at least all of the ones I know of.

I usual SOP with the Saab340B normally has us taking off with 0 flap. Every now and then when there is a high load from a short runway (i.e. Thanksgiving out of the short 4000 ft. runway at DCA they used flaps 5) but about 95% of the time it's 0 flap. But it's a prop.

The only aircraft in CO's fleet to routinely do zero flap takeoffs was the A-300. In theory, given enough speed, I would think most aircraft could do this.... but I wouldn't care to be on the plane that tried it.

The flap setting depends on the Weight of the aircraft and the length of the Runway.
e.g. if you have a short runway but you are a heavy B767 you apply more flaps e.g 30 to get of the ground.
the standard Flap setting is 15 for normal airliners such as the A330..
I don't see why an aircraft can't take of with zero flaps.
if the runway is long enough it should be possible.

A Lufthansa 747 crashed about a minute after takeoff in Nairobi in 1975 because the leading edge slats weren't deployed. They are actuated using pnuematics, which are closed during engine start. Switches were not reset and even though the flap/slat handle was correctly positioned, the slats didn't extend and the aircraft stalled. About 60 passengers were killed. This was after a BOAC 747 had a similar experience at Shannon a year or two previously but a change in start-up procedures was not widely published. The BOAC flight managed to fly away, just.
