percent of maximum RPM. The scale of the tape is 0 to 105%. An adjacent tape
displays N

100%. An amber band extends from 100% to 101%. A red band begins at the
maximum continuous limit of 101%.
The digital value and moving tape are white for N

values above the RPM limit. If the
RPM exceeds the limit for 20 seconds, a L (R) ENG EXCEEDANCE warning
message appears.
A blue bug and blue digital readout between the left and right N
