The MUTCD outlines established practices that are appropriate for determining the recommended advisory speed for a horizontal curve that include an accelerometer, a design speed equation, or a 16-, 14-, or 12-degree ball bank indicator depending on the speed range.During a slipping turn, there is more bank than needed, and gravity is greater than the centrifugal force acting on the ball. The ball moves in the curved glass toward the inside of the turn. As mentioned previously, often power for the turn-and slip indicator gyro is electrical if the attitude and direction indicators are vacuum powered.Heading indicator. The Heading Indicator displays, an indirect indication of bank because a banked aircraft has a natural tendency to turn.; A rapid movement of the Heading Indicator in coordinated flight indicates a large angle of bank, whereas a slow movement reflects a small angle of bank, assuming the same airspeed in both instances.

The term "Ball Bank Indicator" refers to an inclinometer that is used for the specific purpose of determining safe (uniform advisory) curve speeds for horizontal curves.

In New Zealand, the advisory speeds for curves are not regulatory (i.e., they are not speed limits). They are determined using road survey vehicles equipped with a “ball-bank indicator” (or “side-thrust gauge”) calibrated to produce advisory speeds in 10 km/h intervals (Koorey et al., 2001). 2.2.2. Driving simulator

The best method to keep snakes away is through prevention.Note: MUTCD 2009 indicates that the advisory speed corresponding to a 12 -degree ball bank indicator reading for speeds of 35 mph and higher. For speeds of 25 to 30 mph, 14 degrees should be used. For speeds of 20 mph or less, 16 degress should be used To find the angle of banking, you have to know the speed and the radius of the turn, plus the friction coefficient. Considering the maximum allowed speed on a turn, that's how you find the angle of banking: θ = arctan ( (v² - r × g × μ) / (r × g + v² × μ)), where: v is the speed; r is the turning radius;The reading of the ball-bank indicator should be recorded as minus if the deflection of the ball is to the left on a right hand curve and to the right on a left hand curve.
