Section 15. Multi Function Display (MFD)
ITT is continuously displayed on the MFD with a moving tape and digital readout.
The ITT tape range is 0-850°C. An adjacent tape displays ITT limits. A green band
on the limit tape extends from 300°C to the maximum continuous ITT limit. The
FADEC determines the maximum ITT limit, and a red band is displayed beginning at
that value.
The digital ITT value and moving tape are displayed in white for values under the ITT
limit, and in red for values above the limit. An ENG EXCEEDANCE warning
message appears:
If ITT exceeds the limit (but not above 810°C) for 20 seconds
If the ITT reaches 810°C
15.5.3 N2 RPM
N2 is continuously displayed on the MFD with a digital readout in percent of
maximum RPM, and with a moving tape and digital readout on the ENG synoptic
page. The scale of the tape is 0 to 105%. An adjacent tape displays N2 limits. A
green band on the limit tape extends from 45% to 100%. An amber band extends
from 100% to 102%. A red band begins at the maximum continuous limit of 102%.
The digital value and moving tape are white for N2 values in the green band, in
amber for N2 values in the amber band, and in red for N2 values above the RPM
limit. If the RPM exceeds the limit for 20 seconds, an ENG EXCEEDANCE warning
message appears.
