 LOITER to Altitude and QLAND Mode
 =================================
 
-If the previous mode was a fixed wing mode, this mode will perform a descending fixed wing LOITER down to :ref:`Q_RTL_ALT<Q_RTL_ALT>` and then switch to :ref:`QLAND mode <qland-mode>`. If in a VTOL mode, or below  :ref:`Q_RTL_ALT<Q_RTL_ALT>`, when switching to this mode, it will change immediately to :ref:`QLAND mode <qland-mode>`.
+If the previous mode was a fixed wing mode, this mode will perform a descending fixed wing LOITER down to :ref:`Q_RTL_ALT<Q_RTL_ALT>` and then switch to :ref:`QLAND mode <qland-mode>`. The LOITER center is set to the point when entering the mode. 
+
+.. note:: the QLAND target will be directly below the point it switches to QLAND (ie on the loiter circle path, not its center)
+
+If in a VTOL mode, or below  :ref:`Q_RTL_ALT<Q_RTL_ALT>`, when switching to this mode, it will change immediately to :ref:`QLAND mode <qland-mode>`.
 
 This is useful as a Battery Failsafe action to VTOL land the vehicle with as little battery usage as possible if at higher altitudes than using :ref:`QLAND mode <qland-mode>` by itself.
 
-The fixed wing loiter radius is set by :ref:`WP_LOITER_RAD<WP_LOITER_RAD>` and descent rate is :ref:`FBWB_CLIMB_RATE<FBWB_CLIMB_RATE>` to :ref:`Q_RTL_ALT<Q_RTL_ALT>` and when reached will switch to :ref:`QLAND mode <qland-mode>`.
+The fixed wing loiter radius is set by :ref:`WP_LOITER_RAD<WP_LOITER_RAD>` and descent rate is :ref:`FBWB_CLIMB_RATE<FBWB_CLIMB_RATE>` until :ref:`Q_RTL_ALT<Q_RTL_ALT>` is reached, and when reached, it will switch to :ref:`QLAND mode <qland-mode>`.
