A variation of the yaw string is the side string, used in gliders for a determination of the angle of attack. In this way the speed for best glide angle, the best thermalling speed and the stall speed can be observed independently of other parameters like air speed, aircraft weight, acceleration due to turning, stick movements, and gusts.

angle of attack α: angle between the x w,y w-plane and the aircraft longitudinal axis and, among other things, is an important variable in determining the magnitude of the force of lift When performing the rotations described earlier to obtain the body frame from the Earth frame, there is this analogy between angles:
A drift meter consists of a small telescope extended vertically through the bottom of the aircraft with the eyepiece inside the fuselage at the navigator's station. A reticle, typically consisting of spaced parallel lines, is rotated until objects on the ground are seen to be moving parallel to the vertical lines.
A New Jersey deli is crafting 2-foot-tall ravioli Christmas trees — and they’re fry-ing off the shelf. Taliercio’s in Middletown, NJ, shared their festive Italian creation, ...
WASHINGTON (Reuters) -The outgoing and incoming U.S. presidents had different messages for the Christmas holiday on Wednesday, with Democrat Joe Biden urging Americans to reflect and unite, while ...
2. Add Protein and Fiber to Your Plate First. Protein and fiber can help keep your hunger in check and make you feel fuller for longer. There’s even research suggesting that high-protein ...
The command signal is displayed on the attitude indicator in the form of command bars, which show the pitch and roll inputs necessary to achieve the selected targets. [ 2 ] The pilot simply keeps the aircraft symbol on the attitude indicator aligned with the command bars, or allow the autopilot to make the actual control movements to fly the ...
The drift angle (shaded red) is due to the wind velocity (W/V, in green). In navigation, the heading of a vessel or aircraft is the compass direction in which the craft's bow or nose is pointed. Note that the heading may not necessarily be the direction that the vehicle actually travels, which is known as its course.
