What is it?

[Richard]

If you know the purpose for the long tail pipe don't answer just yet so others can have a crack at it.

 

[Pi1otguy]

Squirt a lil diesel in there and instant smoke?

 

[Teller1900]

We had a plane with almost that exact same set up come into Augusta last month, I was so curious I had to ask them on the radio what it was. Surprisingly easy solution for that problem.

 

[infotango]

I know!

Brilliant solution to the problem.

 

[Pi1otguy]

belly icing prevention?

 

[TMetzinger]

I'm pretty sure I know what it is... is the airplane currently in a category other than normal?

 

[Everskyward]

I can't open the picture to see the details but from what I can see, I flew an airplane with a similar setup so I think I know what it is....

Edit: I got the picture to open and I'm even surer that I know what it is...

 

[t0r0nad0]

No clue... those who do know, please tell.

 

[Pi1otguy]

At the very least, what is the problem it solves?

 

[Ghery]

Tim, the Toolman, had a saying that answers the question.

More power?

 

[Shipoke]

Noise suppression Maybe?

[Dwight B. Van Zanen]

I am going with noise reduction. I understand that the Border Patrol drones have a 6 blade prop and a long exhaust to remain undetected. This could be to reduce noise in the cabin for the traffic reporter so he can talk on camera live.

 

[Danos]

I know I know!

At the very least, what is the problem it solves?

That would be giving the answer.

 

[Pilawt]

Looks like I may have parked next to the same airplane at Provo UT last year ...

And no, I don't know the answer to the question. (I blanked out the reg in the photo so as not to give away that clue.)

 

[tonycondon]

interesting hole in that baggage door...

 

[TMetzinger]

OK, where I've seen these elongated exhausts were on planes used for photography or other sensor packages, the long pipe keeps the exhaust products from interfering with the camera or sensors.

Urine evacuation tube?

I think you are on to something. If that hole in the baggage door is for a camera - or even better an infrared camera - the long pipe is to lead the hot exhaust behind the camera port so the exhaust heat doesn't scramble the infrared photographs.

Bingo.

 

[gprellwitz]

Yesh, we had a plane in here at Clow a couple months ago, and I went up and asked, because it wasn't immediately obvious! But it is a great solution. Not just for infrared, but because the heat and exhaust causes distortion of the photos.
