SYSTEM DESCRIPTION
(Continued)
The EIS strip on the MFD displays TKS (anti-ice) fluid quantity and time
remaining feature to aid the pilot as to the amount of fluid/time available
for ice protection. The system uses a series of colors to alert the pilot
as to how much time is remaining based on fluid quantity and ANTI-ICE
FLUID CONTROL switch position. Green readout informs the pilot of at
least 20 minutes of ice protection with the PRIMARY switch in NORM; 8
minutes with the PRIMARY switch in HIGH.
ANTI-ICE fluid quantity and time values displayed against an amber
background with black text alerts the pilot of less than 20 minutes of ice
protection with the PRIMARY switch in NORM; less than 8 minutes with
the PRIMARY switch in HIGH.
ANTI-ICE fluid quantity and time values displayed against a Red/White
(reverse video) background alerts the pilot of less than 0.5 gallon of
fluid. That equates to 5 minutes of ice protection with the PRIMARY
switch in NORM; less than 2 minutes with the PRIMARY switch in
HIGH.
When BACKUP is selected, the time remaining function is unreliable
and must not be used.
A wing inspection light, controlled by the WING LIGHT switch, is
provided to illuminate the leading edge of the left wing during night
operation.
