Groundspeed Hold Mode is a sub-mode of Attitude Hold Mode in
which the control of attitude is augmented to achieve a control
objective of constant lateral and longitudinal ground speed.
Entry into and out of Ground Speed Hold Mode is automatic.
A servo function which maintains aircraft pitch and/or roll
attitude. This function moves the rotorcraft flight controls to
maintain the attitude. When the pilot moves the controls, the
servo provides a spring feel which helps the pilot move the
controls to achieve the reference attitude.
A hands on controls function which provides an increased force
gradient or control force cue to deter additional pilot control
inputs which would exceed configured rotorcraft limits.
An attitude hold sub-mode used to return the aircraft to a level
pitch and roll attitude.
The control position at which the pitch and roll control objectives
have been achieved. Moving the controls away from this position
will provide resistance to the pilot. Upon release of the controls
they will return to the detent position.
A function that provides pitch and roll commands to the pilot or
servos, based on the pilot-selected mode(s) on the GMC (HDG,
NAV, IAS, ALT, etc.). Modes are classified as either "Active" or
"Armed".
A state of the flight control system where the servos are not
engaged and the optional flight director is OFF. H-ESP (Limit Cue
protection) is still active when the system is in standby to protect
the pilot from exceeding the operating limits of the helicopter.
