Study Notes
Ground Mode Lateral Control
- Sidestick controls ailerons and roll spoilers.
- Control surface deflection varies with aircraft speed.
- Pedals control rudder directly.
In-Flight Mode Lateral Control
- Normal law combines ailerons, spoilers (except spoiler 1), and rudder for turn coordination.
- Flight crew does not use rudder for turn coordination.
- Flight control system limits roll rate & bank angle, coordinates turns, and dampens dutch roll.
- Roll rate is proportional to sidestick deflection (max 15°/s).
Flare Mode Lateral Control
- Lateral control is the same as in "in flight" mode.
Decrab Phase Lateral Control
- Aircraft limits induced roll after pedal input to ease control.
Transition Between Modes
- Aircraft smoothly transitions to/from "in flight" and "ground" modes.
