• RIGHT: Ice protection fluid is drawn from the right tank
regardless of sensed quantity.
System Indicating
System Indicating is displayed as bar graphs and text in the lower left
corner of the MFD ENGINE page. The bar graphs, marked from 0 to 4
U.S. gallons in 1-gallon increments, indicate LH and RH tank fluid
quantity. Fluid quantity is also displayed numerically below the bar
graphs in 0.1-gallon increments. When the system is operating in the
default, automatic tank selection mode (AUTO), a white box is
centered around the "L" and "R" located above each bar graph and a
cyan box is displayed around the selected Anti-Ice System mode.
During normal operation, the white box will switch between the left and
right tank as the fluid level changes. In the case of an electronic
display failure (reversionary mode), fluid quantity is displayed along
the LH edge of the PFD and the system maintains the tank selection
mode that was current when reversionary mode was activated. Manual
tank selection mode is selected by pressing the ANTI-ICE softkey to
access control of the LEFT and RIGHT tanks. In manual mode, a cyan
box is displayed around the selected tank, gallons remaining in that
tank, and the selected Anti-Ice System mode. Pressing AUTO returns
the system to automatic tank selection mode.
System Endurance is displayed on the MFD ENGINE Page for the
different system modes based on the total sensed fluid quantity and
published system flow rates. A cyan box depicts the user selected
system mode. System Range is displayed on the MFD ENGINE Page
for the selected system mode based on the calculated system
endurance and the current ground speed.
If tanks are selected manually, system range and endurance
calculations use only the sensed fluid quantity of the selected tank.
While in PUMP BKUP, system range and endurance calculations use
the sensed system flow rate of the flow meter.
Refer to the Perspective Integrated Avionics System Pilot's Guide for
additional information on system annunciation and control.
