7.2.6.6 Cabin ventilation control (Electrical option)
For aircraft equipped with the ergonomic control system, the cabin
ventilation system is electrically adjustable via the ergonomic control
panel.
To adjust the ventilation, rotate the selector switch to select either the
eyeball vent or demisting function. Adjust the ventilation using the control
switch as follows:
• Up (+): Increases airflow
• Down (-): Decreases airflow
The eyeball vent, positioned on the right-hand cockpit sidewall, is used
to direct the airflow as desired and may also be used to regulate the
airflow rate (Figure 7.2-13).
