Turn Rate Indication
The EFI depicts turn rate as a magenta bar along the top of the
compass card. Fixed reference marks indicate left/right 1.5°/second
and 3°/second turns. The bar is capped with an arrowhead when the
turn rate exceeds 4.5°/second left or right. Turn Rate is displayed on
either the Full or Arc compass card. When there is zero or no turn rate
the indication is removed from the display.
