Definition
On an electronic flight display turn indicator, a horizontal graphical element that moves left or right along a fixed scale to show the rate and direction of turn. It replaces the moving needle of a traditional turn coordinator, with displacement from center indicating how fast the aircraft is turning and on which side.
Plain English
A small bar on the screen that slides sideways to show how fast you are turning and which way. The further it slides from the middle, the faster the turn.
Context Anchor
Seen on an electronic flight display when checking turn direction and turn rate, especially during instrument flying or instrument practice.
Why Pilots Care
It is the EFD equivalent of the turn coordinator. Reading it correctly lets a pilot establish and hold a standard-rate turn, which matters for instrument procedures, holding patterns, and flying without outside visual references.
Intuition Check
Do not think of the sliding bar as a physical cockpit control. In this context, it is a display cue for turn direction and turn rate, not a bar the pilot moves by hand.
Example Sentence 1
Entering the hold, the pilot rolled into a bank until the sliding bar lined up with the standard-rate index.
Example Sentence 2
With the sliding bar centered, the airplane maintained coordinated flight through the procedure turn.
