Flightsimware Bell 47

I sent flightsimware a question for their Bell 47 Last month and never heard from them.

Question was, what is the red strip in the center of the cockpit glass for?

Didn't see it mentioned in the flight manual. I think one time the bottom of the red strip would flip up.

Looks like it's supposed to be a yaw string, does it move?

Yes it does. Good way to watch if you're slipping.

Yep. That's what is .

Thanks for the info, now as I took off in the Bell47, it flipped upwards. What does that indicate? When I land it will flip the other way,
only up or down movement.

This 'Yaw String' works in a simple way.

The airflow over the canopy moves the string to align with the relative airflow.

If it's parallel with the centre line of the aircraft you're flying balanced.

If it's off to one side use more rudder to balance the aircraft and bring the string vertical.

The reason it hangs down when you're not moving is because of gravity.

As any glider pilot knows the string is your best friend.

I was going to say, old school but still a standard "gauge" in a glider.

Even the F-14 had a yaw string.

DCS gazelle has one too, much needed for hovering.

Did not know that. I never was aware of a yaw string till I had asked about the red ribbon in the
middle of this Bell 47 helo,

Now with yaw being the left and right movement of the nose of the aircraft, In this bell 47, the yaw string was modeled
to move either up or down and no left/right movement as it (string) doesn't pivot left/right.

I do notice that on the ground, the string in down and if I slowly lift the helo off the ground a few feet, the string will be down and
eventually and with a bit more altitude, the string will flip up. The sting on this mode will not pivot left or right as I turn the nose of
the helo in those directions.

No biggie, just was trying to understand the science behind it all as it relates to Flightsimwares Bell 47.

Thanks for all the info.

This video demonstrates a yaw string on a helo. It is mounted in such a way so as to freely move in any direction such as a weather vane.

On the Bell 47, the string was flush mounted to the cockpit glass which confused me at first.
