Jul 15, 2018 · The yaw string indicates how well the longitudinal axis of a flying machine is aligned with the relative wind; nothing more, nothing less. A gyro can make a zero radius turn at zero translational airspeed; -prop blast over a deflected rudder- but …

Oct 21, 2006 · When I first read "Think of the yaw string as a snake and step on the head," two initial questions popped into my thoughts - the answers probably obvious to everyone else: 1) Which end is the head? Both a snake's head and tail move; 2) …

Mar 17, 2015 · The relative wind is obviously blowing the string away from it, so to coordinate you have to turn into that relative wind, which is the opposite way (pedal) from the direction the string is being blown, just like a windsock.

Oct 31, 2003 · A yaw string, Fergus, is the only aviation instrument that never lies. If it says you’re going backwards, you are. Back in the days of my youth, as a tech rep for the manufacturer of the gyro gunsights on Sabrejets (F-86s), one thing that caught my eye was that nearly every one had a yaw string attached to the nose hatch with a black longitudinal line painted underneath. The pilots said they ...

Mar 25, 2014 · In an open frame gyro a yaw string wouldn't make a huge difference. Just stick out your tongue. If your right cheek gets wet you need some left rudder and vice versa. However, in a closed gyro or one with a serious wind screen it is a valuable instrument. Particularly if you want to fly straight a lot (probably doesn't apply to birdy ). -- Chris.

Apr 26, 2013 · The yaw string is a tool for developing and maintaining finesse and mastery throughout the flight envelope; the performance gain is secondary for me. And it is certainly harmless.

Nov 7, 2004 · Expensive yaw string I bet Expensive yaw string I bet Our Lockheed T-33 trainers (where I used to teach) had a yaw string attached to the forward windscreen molding. Inside the nose machine gun bay (radio bay in the trainers) there was a small manila envelope attached to a bulkhead. The envelope was marked "Indicator, yaw".

Apr 28, 2013 · I like the yaw string. I have to agree that there have been times in some machines where it felt as if the machine "labored" less if the string was NOT straight back. It felt like the emergency brake was dragging when I'd rudder the string back into alignment. Hey, Vance, I thought I made up that little mnemonic: "The string is a snake.

Oct 30, 2003 · Most important instrument needs no battery. I hope you put a yaw string on your machine.

Jul 2, 2007 · A yaw string has to be the most essential , simplest and problem proof gyro instrument out. The ballistic parachute a wonderful invention, though sadly, not easily adaptable to a gyro.
