Two questions about the attack chopper

Alright, I've got 2 quick questions about the chopper. I've been flying for awhile and I cannot find out anything relating to this. The first question, What is the stick thing that ejects from the WZ-10 (Chinese Attack Chopper) between the pilot's and gunner's window? You can even see it on the BF2s wiki picture here. Secondly, what is the 2nd circle on the chopper, when you take off, it floats off and dissapears. It's slighty larger and starts off around the crosshairs, but then moves around. I thought it had something to do with the TV guided missles, but I'm only guessing on that. Can anyone give some more information on that? Any input would be appreciated.

Here is a picture of the circle in question.

The bigger circle is a tool for helping you hover. If it is in the middle, then you are hovering perfectly still. If it is off the the side or up or down, it means you are drifting.

First question.. no idea what you're talking about.

That circle however, I believe, is to indicate how close you are getting to the ground. It reaches the center as you reach the ground, and disappears off to the bottom of the screen as you clear a certain elevation. That's why you see it while you are landed, and it goes away as you are taking off.

Ahh, thanks for the input, when I get home I'll take a screenshot showing what I'm talking about on the first question.

To answer the first question, I believe the "stick thing" is the pitot tube, which measures air speed. Basically air goes in the front of it, and air speed is determined from the velocity of the air moving into the tube. If this were real life, you would have to determine wind velocity and direction, and do some calculation based on your air speed to get your ground speed, but this isnt real life and there is no wind. And somehow the pitot tube can measure air speed when you're going backward, and theres no air being pushed through it.

Ah, I was just wondering becuase I never noticed it on other choppers. Well here are the pics, I had them uploaded anyways...

The way its shaped doesn't seem to reflect a wind measuring instrument to me, otherwise I imagine it would be horizontal. Could be something to do with the ejecting cockpit, like a GPS transmitter. Could be some sort of sensor for target acquisition or ambient temperature.

Information on the WZ10 seems really scarce.

It's a "take-a-away" food pickerer-upperer, how else do you get the McChunder from the drive thru window?

Either that or a fancy cup holder (for hot drinks only...to cool em down)

Im fairly sure thats the probe for in air refueling.
Either that or some kind of radio/radar mast.

its definitly either a pitot tube or some other kind of air data probe

Probabluy something radio orientated. Mid-air refuelling in a chopper dracul? where do you get your info? Theres a slight problem with the LARGE SPINNING BLADES above it. Kinda hard to get a pipe throuigh them.

some choppers can in-flight refuel, but they have a long probe in the front to clear the main rotor. an in-flight refueler probe wouldnt be that spindily looking either...

edit: the cobra has one too

Um. when the rotors are spinning at full speed, they are bowed upwards, because the blade-tips ar traveling faster than parts closer to the shaft.

Besides, they use a drag-parachute called a "drogue" to slip it in under the rotors.

(but amox is still likely correct)

The stick is a cupholder. Put ur beer in it and go kill someone!

The extension in question is most likely the refueling probe but it almost looks too small for that.

FYI: The pitot tube is visible just to the front and below the gunner's canopy; it's the small green elbow-like protusion.

It couldn't be a pitot for determining airspeed: I think its pointed up too much so it would get too much direct wind from the rotors.

I highly doubt its a refuel probe becuase it is not nearly long enough. Normally the probe goes at least to the edge of the rotor disk.

Yes helicopters can airial refuel. The refueling hose has wings on it that make the end lift up.
Just watch this video to see a helicopter refueling in action: http://www.alexisparkinn.com/photogalle … ident.mpeg

This is not true. The edge is moving faster than the center but the blades slightly twist so the angle of attack is more at the center. They bow because of the weight of the helicopter is pulling in the middle. When the blades are turning on the ground they are straight out.
Try this experiment: Hold yourself up between two tables with your arms extended fully outward. They will bow aswell.

So my guess is that its some sort of antenna, or they just moddeled the pitot tube wrong, because the one on the cobra does look like it is a pitot tube.

I wonder if that guy had to pay for a new tube, he cut his off... rotfl. I wonder how often that happens because it seemed to happen fairly easily.

I crew the CH-47D in the army and its the only case I've heard of. It was all pilot error. He should not have dove after the hose, and he also shouldn't have come right back up so quickly. With the chinook there are limits that the pilots have to follow [60 degree max bank, max rate of decent, etc] and I'm sure there is one for that. So it was all pilot ignorance.

Just to correct my first post, the little circle is indeed an indicator to show how well you are hovering, not how close the ground is. It just happens that you are hovering perfectly when sitting flat on the ground.

And the little stick? Windshield wiper of course!
