Definition
A condition in which an indicator, control, or component is positioned at the midpoint of its travel or display, with no deflection to either side of a reference point.
Plain English
Sitting right in the middle, with equal space or movement available on each side.
Context Anchor
Seen in cockpit instrument indications, flight control position, trim use, and runway or taxiway alignment.
Derivation
Centered comes from center, from Greek and Latin words meaning a sharp point or fixed middle point. That helps because in aviation, centered usually means matched to a clear reference point or middle position.
Why Pilots Care
A centered indicator often signals 'on course' or 'in trim,' so recognizing the centered condition is the basis for many flight corrections and navigation decisions.
Intuition Check
Centered does not just mean generally neat or balanced. In aviation, it means aligned with a specific middle or neutral reference.
Example Sentence 1
When the CDI needle is centered, the aircraft is tracking directly along the selected course.
Example Sentence 2
With the ailerons and elevator centered, the airplane held straight and level flight.
