Throttle Hold
The Function Menu List is accessed from the Information Display Screen by pressing the LIST key. From the Function
Menu List, rotate the Scroll Bar to highlight the "THRO Hold" menu choice and click the Scroll Bar. The default is for the
Throttle Hold to be inhibited.
The Throttle is held in a pre-selected position by the operation of the Throttle Hold switch, while the Throttle stick
continues to control the Rotor Pitch. This is usually used to practice auto-rotation landings. Absolute Throttle positions
between -20% and +50% can be set. The Throttle hold can be automatically inhibited by the Throttle stick position and a
transition delay of up to 2 seconds can be introduced to slow the Throttle response when the hold is deactivated.
To activate Throttle Hold,
click the Scroll Bar to toggle between INH (inhibited) and ACT (active). The screen will
appear as above with minor variations depending on previous settings. Notice that ON appears adjacent to [THRO Hold]
when the Throttle Hold switch is operated.
To set the Throttle position,
highlight "HOLD Pos." by rotating the Scroll Bar and click on it to bring up the sub menu.
The figure is surrounded by a box to indicate that it is selected. Rotate the Scroll Bar to alter the setting. To return the

achieved, click the Scroll Bar to exit the sub menu.
To set a Throttle stick inhibit position,
highlight "STICK AUTO" by rotating the Scroll Bar and click on it to bring up
the sub menu. The wording is surrounded by a box to indicate that it is selected. Rotate the Scroll Bar to alter the setting.
Figures between zero (INH) and 100 may be entered. To return to INH (inhibited), press the clear (CLR) key at the left
hand side of the screen. When the required setting is achieved, click the Scroll Bar to exit the sub menu. A zero entry
corresponds to the Throttle stick at minimum and 100 corresponds to the Throttle stick at maximum. When the Throttle
stick is above the entered position, the Throttle Hold switch is inhibited.
