Hi.
Was on a Fokker 100 yesterday for the first time and noticed that we took-off with no flaps set. I know that it is common practise on A300 if conditions are good. Which airliners can do this also under normal passenger/cargo operations?

Some DC-9 family aircraft do them, though always with slats.

The 767 can do a flaps 1 (slats only) takeoff

As can the 170. Usually done in hot/high conditions.

I thought Flaps 1 did entail a very minor flap extention...

The first time I was on a F-100 was shortly after the NW and DL no flap takeoffs and accidents and I was double cinching the seat belt as we rolled down the runway.

I thought that flaps 1 (slats only) was do-able in the 767-200, but not the -300 nor -400?

As long as the aircraft was delivered with a certification for a flaps 1 takeoff and you have performance for it you're allowed to do it. As far as I know the -300's were not delivered with this modification (at least ours aren't). I can't speak for the -400, but I believe the -200 was certified for a flaps 1 takeoff

What, you never said anything about them having to be JET powered Big grin 112hp twin blade prop all the way, baby!  Silly

Vr at flaps 0 is 60, Vr at flaps 1 is 53 (short field only for flapped take off, though), FYI. Don't ask on the amount of runway that'd use on a T/O run, I have a 7500 foot runway to use so length for me isn't really an issue...

Actually, most aircraft that are single engined (only exception to that I can think of is maybe the Cessna Caravan) take off with no flaps, they usually have no need to.

Piper Senecas and Navajos. I cant remember what the books say but we never used flaps for takeoff.

According to our flight manuals the 200ER's are the only ones that can do a Flaps One take-off. The 767-300ER's are Flaps Five

For sure I was a bit nervous about that cause I had the accidents in my mind.

A300's do it all the time, notably UPS; I rarely see a UPS A300 takeoff that doesn't use just Flaps 1. They usually have a longish takeoff run (often around 6K ft. for a <3 hour flight), yet they climb quite steeply.
Interestingly enough, I've noticed that FX and AA A300's seem to rarely perform Flaps 1 takeoffs.

Fokker 70, hehe.

The 70 and 100 can also do a Flap 8 takeoff, though it has to be heavy, hot, high and short before it comes to that! Or on a contaminated runway because of a lower takeoff speed reducing the roll.

whatabout the CRJ's and ERJ's?

Hm... if it's you asking this question, 2H4, it could very well be the obscurest, least-known flying object around  Big grin


I am, therefore I think.

Well, delta-wing aircraft are obvious (Concorde, Vulcan, etc), as delta wings rarely (never?) have flaps anyway. The lack of flaps on those aircraft is not particularly surprising.

So really, the more interesting question is, what is the largest non-delta-wing airplane not equipped with flaps?

The only ones I can come up with are small ones. Cessna 120, Pitts, Extra 300. I can't think of any larger examples.

A couple of weeks ago I was on a US Airways 767-200 and we took off from Bermuda with no flaps. I was behind the wing, so I couldn't see whether the slats were extended or not.
