Which Aircraft Can Take Off Without Flaps?
 
The Spanair thread has raised interesting questions in relation to passengers' awareness of problems and whether they should inform the crew when they think something is wrong. One contributor, "sevenstrokeroll", says that some 'planes do not use flaps for take off.
I'm sure I'm not alone in wondering which particular aircraft are cabable of taking off safely without flaps.
If this is not the appropriate place, moderators please move this post.
If the question has been posed (and answered) elsewhere on PPRnNe I'd be grateful to know where.
Many thanks.

Not a daft question, just before I crossed over to the 'Dark Side' and left rotary for fixed wing, (and with a freshly issued CPL/A in my flight bag) I was a passenger with LH from LHR to FRA in a A310 or A300. I was sitting abeam the trailing edge of the right wing. As we taxied out, I realised with growing alarm that there were no trailing edge flaps being deployed and I was unable to see the slats. I actually quickly undid my seat belt and stood up to see if the left hand flaps were out, which they wern't. I then spent an agonising time considering whether to jump up and down waving my arms like a stung turkey screaming 'stop the take-off, stop the take-off' but didn't. I assumed with a great deal of trepidation that the LH were doing the right thing and the Airbus was quite happy getting airborne in this configuration. However until the thing flew I kept having recollections of the Dryden Ontario icing accident going through my mind: 'The guy who didn't speak up'. It's amazing how we are so reluctant to embarrass ourselves.

A suggestion from a once frightened passenger to all those pilots of aeroplanes which don't need flaps for take-off, please tell us in the welcoming PA, you will have less deaths from incipient heart attacks.

I've not flown any Fokkers but am led to believe that Flap 0 us not unknown on the F28/F70/F100. And no LEDs either!

I have seen a Baron58 do it, ate the runway more than it should, but that was certianly interesting...

airmanbg 7th Sep 2008 09:15

Actually they take off with Flaps 0 most of the time. :ok:

sthaussiepilot 7th Sep 2008 09:21

Must have been the pilot....

I usually use them on take off, well I was told to anyway...

I don't recall any performance figures for a Beech Baron using Flaps for take-off.

B1900 We used the first bit of flap for take-off, (I think 15), further avoidance of tailstrike, lower speeds for lift off, short ground run, if I remember, in accordance with the flap 15 performance POH.

Strange:confused:

Oh Well,,,

In the B733 we use Flap 5 most of the time, very rarely Flap 15 or Flap 1, and if we press the TOGA Buttons (to set takeoff thrust) and if the throttle was to advance forward without flaps, we get a aural warning!!!

On airbus A310 we can do Slats 15 zero flaps takeoff

Bullethead 7th Sep 2008 10:05

Concorde did it for years!

Flight Detent 7th Sep 2008 10:14

Good one Bullethead.....so did the Vulcan bomber...and so do the Mirage fighters...I wonder what's common between all those?

Hey Jinkster, you know, that may also happen during takeoff without using the autothrottle, you might try it some time!

I'm gettin' to old for this....I'll get my coat...:ooh:

Jinkster 7th Sep 2008 10:20

Hi FD,

Yes it certainly does! Thats how we test it in the mornings!!

ForkTailedDrKiller 7th Sep 2008 10:43

The BE35 takes off quite nicely with Flaps 0!

My single seat Druine Turbulent powered by a 40 yr. old 1200 cc Beetle engine doesn't even have flaps. Mind you, it has fixed 'slots' which keep the wing pretty well controllable and gives a very mild stall - this was designed 60 years ago. They knew a thing or to then. :ok:

The F27 did it for a better 2nd segment performance.

Chesty Morgan 7th Sep 2008 11:37

All of them...if the tarmac is long enough:}

Captain Capstan 7th Sep 2008 11:42

The Boeing 767-200 uses leading edge slats and no trailing edge flaps with flap 1 selected . Used to use it regularly out of Singapore.

I discovered recently, on a flight from GLA - AMS, the F-70 can perform a flapless T/O. I was sitting just behind the trailing edge of the wing, it was a very long 5 min taxy from the stand to runway :uhoh: I thought about calling the F/A and quietly expressing my concerns but decided not to. I figured if the F-70 is anything like the 737 then the pilots would get an earful as soon as they advance the throttles on T/O without flaps. We departed without flaps and the we seemed to get airborne pretty quickly.

I dont think the deltas have flaps? Considering their position they would act like elevators, wouldnt they?
