In versions 4.4 and later, the ability to conduct power re-engagement from an autorotation has been added. This feature will work with ESC's using their built-in governor, the ardupilot throttle curve or the ardupilot built-in governor. Three parameters were added to accommodate this feature.

* :ref:`H_RSC_AROT_MN_EN <H_RSC_AROT_MN_EN>` - Enables manual autorotations (0 - Disable, 1 - Enable)
* :ref:`H_RSC_AROT_ENG_T <H_RSC_AROT_ENG_T>` - Time to ramp throttle back to motorlock enabled value during power recovery in seconds
* :ref:`H_RSC_AROT_ENBL <H_RSC_AROT_ENBL>` - Enables manual autorotations (0 - Disable, 1 - Enable)
* :ref:`H_RSC_AROT_RAMP <H_RSC_AROT_RAMP>` - Time to ramp throttle back to motorlock enabled value during power recovery in seconds
* :ref:`H_RSC_AROT_IDLE <H_RSC_AROT_IDLE>` - Idle throttle value in percent used during autorotation. This can be set to the value that signals the ESC to perform a fast spool-up when performing a power recovery.

ESC Governor
------------

Enable manual autoratation by setting :ref:`H_RSC_AROT_MN_EN <H_RSC_AROT_MN_EN>` to 1. Leave :ref:`H_RSC_AROT_ENG_T <H_RSC_AROT_ENG_T>` at the default setting of 1 second to quickly signal the ESC for fast spool-up. Set the throttle idle value, :ref:`H_RSC_AROT_IDLE <H_RSC_AROT_IDLE>`, to the percent of throttle given by the ESC manual that signals the ESC to perform a fast spool-up.
Enable manual autoratation by setting :ref:`H_RSC_AROT_ENBL <H_RSC_AROT_ENBL>` to 1. Leave :ref:`H_RSC_AROT_ENG_T <H_RSC_AROT_ENG_T>` at the default setting of 1 second to quickly signal the ESC for fast spool-up. Set the throttle idle value, :ref:`H_RSC_AROT_IDLE <H_RSC_AROT_IDLE>`, to the percent of throttle given by the ESC manual that signals the ESC to perform a fast spool-up.

Ardupilot's Throttle Curve or Built-in Governor
-----------------------------------------------

Enable manual autoratation by setting :ref:`H_RSC_AROT_MN_EN <H_RSC_AROT_MN_EN>` to 1. Set :ref:`H_RSC_AROT_ENG_T <H_RSC_AROT_ENG_T>` to bring the throttle back to the throttle curve quickly. One to two seconds woudld be sufficient. If desired, the throttle idle value, :ref:`H_RSC_AROT_IDLE <H_RSC_AROT_IDLE>`, can be set to a higher value for ICE engines to remain at a higher engine RPM in the descent. For electric engines using the throttle curve or built-in governor, set it to zero.

Semi-Autonomous Autorotation Setup
==================================

Future enhancement to provide autonomous control during autorotation is planned as a new flight mode. Currently under development, the current state of the project can be tried under :ref:`SITL Simulation <sitl-simulator-software-in-the-loop>`. See :ref:`traditional-helicopter-autorotation-mode`
