Feb 23, 1999 · The ball of the turn-and-bank indicator is actually a separate instrument, conveniently located under the turn needle so the two instruments can be used together. This instrument is best used as an indication of attitude. When the ball is centered within its glass tube the maneuver is being executed in a coordinated manner. The proposed speed limits are based on speed studies, topography, and ball-bank indicator tests performed on the horizontal curves. RESO - Gunnison Rd speed limit 9.6.23.pdf.
