The methods used to determine the appropriate advisory speed for any given horizontal curve will also be discussed, including updated information on the use of ball bank indicator speed thresholds. The ball-bank indicator reading is a function of the lateral acceleration and roll rate of a vehicle. From this, a speed at which drivers will become uncomfortable while traversing a horizontal curve can be determined. The MUTCD ball-bank indicator method assumes a constant friction threshold for all speeds, which is not necessarily applicable ...Most officially sized tennis balls have a circumference of about 8.258 inches.

It measures the overturning force (side friction), measured in degrees, on a vehicle negotiating a horizontal curve - whether it is an isolated curve, multiple "S" curve, or a ... determining appropriate and uniform speeds for such signs has long been the ball-bank indicator; however, debates over suitable ball-bank thresholds continue and inconsistent standards between jurisdictions persist. Moreover, research regarding the effectiveness of advisory speed/curve signs in general has been long neglected.Jan 1, 2019 · The turn coordinator is similar to the turn and bank indicator, which senses roll (but not yaw) and displays rate of turn (see “Turn and Slip Indicator,” this page). When you turn on the airplane’s master switch, the electrical system will power up the turn coordinator’s gyro, and its warning flag should stow within about 30 seconds to ... A ball-bank indicator (sometimes referred to as a slope-meter), shown in Fig. 1, is the most popular tool used to mark advisory speeds on curves. Its popularity has arisen from its simplicity of use and construction. The ball-bank indicator consists of a small steel ball sealed within a glass tube. The glass tube represents part of a circle and ...

The meaning of BALL-BANK INDICATOR is a bank indicator consisting of a slightly curved tube in which a ball remains centered while the airplane is flying straight and level or while the airplane is making a properly banked turn.An example of a ball-bank reading is illustrated below in Figure 2.
