Definition
A side-to-side movement of the helicopter's cyclic control stick, which tilts the rotor disc left or right to produce lateral (sideways) movement of the aircraft.
Plain English
Moving the cyclic stick left or right to make the helicopter lean and move sideways in that direction.
Context Anchor
Seen in helicopter instrument flying when discussing how a pilot starts, controls, or stops a turn.
Derivation
Lateral comes from the Latin lateralis, meaning 'of the side.' Cyclic refers to the control that changes rotor blade pitch cyclically — once per rotation — to tilt the rotor disc. Together: the side-to-side use of that control.
Why Pilots Care
Precise lateral cyclic inputs let the pilot establish and hold the exact bank angle needed for coordinated turns during instrument flight.
Intuition Check
Lateral does not mean forward or backward here; it means side-to-side. Cyclic does not mean a repeated event here; it means the helicopter control stick used to tilt the rotor.
Example Sentence 1
The pilot applied a small amount of left lateral cyclic to correct for a gust drifting the helicopter to the right in the hover.
Example Sentence 2
Smooth lateral cyclic corrections kept the helicopter aligned with the localizer during the approach.
