TRIM INDICATIONS

Pitch, aileron, and rudder trim indications are provided on the EICAS
and the MFD. A digital display of pitch trim position (PIT TRIM) is al-
ways in view below the CAS window, on the right side of the EICAS.
Pitch (PIT), aileron (AIL), and rudder (RUD) trim are digitally dis-
played on the SUMRY page. They are arranged in a vertical column la-
beled FLT on the right side of the SUMRY page. The SUMRY page is the
power-up default display on the EICAS. The SUMRY page is displayed
at the base of the MFD. Trim indications are correspondingly displayed
on the left side of the FLT system schematic page.
The following CAS illuminations are specific to the trim indications:

PITCH TRIM INDICATIONS

Pitch trim tab position is presented as both analog and digital display.
The label PITCH, in cyan, is positioned above the pitch trim tab posi-
tion digital readout. The range of pitch trim is from 0 to 10, and with 0
being maximum nose down trim and 10 being maximum nose up trim.
The analog scale consists of a white vertical line with three horizontal
tick marks on the right side. The labels NDN and NUP are displayed at
the left top and bottom of the scale, respectively. The digits 0 and 10 are
displayed at the right top and bottom of the scale, respectively. The
analog scale has a white takeoff band located between 5.5 units and
8.7 units. There is a pointer which moves up and down the left side of
the scale in accordance with the digital readout of the pitch trim tab po-
sition. If the pitch trim is not within the takeoff band, and the airplane
is on the ground, the digital display of trim will have a white box
around it and a message posted to CAS. If power is advanced for take-
off (MCR or greater) and pitch trim is not within the takeoff band, the
"CONFIGURATION" voice warning will sound and the CAS message
turns red along with the digits, pointer and box in the trim position dis-
play. Invalid data will replace the digits with amber dashes, and the
pointer and box are removed.
