It's a polish plane:)

@wono77 Actually it's an american plane made by Air Tractor, a company located in Texas.

Yeah i realise this, but it's not usually blue (hotter), or that constant, correct?

[UFischdick]

When flying at dawn, dusk or night depending on the engine settings you can see flames out of the exhaust that are maybe 3 feet long. Usually when cruise flying the mixture setting will reduce the amount of unburnt fuel that can generate the flames.

[Dauntless244]

Constant blue exhaust flames is a bit unusual isn't it? What caused that?

[UFischdick]

Radial engines use carburetors and when operated in full rich mixture there's an excess of unburnt fuel that ignites on the exhaust pipes. That's the cause.

[paperkiller25]

its running rich. The extra fuel burns in the manifolds. At low RPMs many engines are run rich to help cool the engine.

@UFischdick a polish company called PZL used the same designs though.

[Mechknight73]

I think close relatives of these planes work as fire bombers in Western Australia. Coincidentally the same shade of yellow, they are used almost like a crop duster to "bomb" bushfires

[zemikel]

[doubtfuldjs]

dont these planes spray either fertiliser or bug killer over crop feilds? i saw them on a tv show once
