9. MODIFY QM > 150% Pressing L-5 displays the cursor next to the L-5 legend allowing the operator
to enter a number between 0 - 99 for the QM > 150% counter. After pressing
the ENTER key on the MFK, the number is displayed next to the text # OF
COUNTS IN XMSN LIFE. If an invalid entry is made, the entry is blanked,
the cursor reappears and the text ERR is displayed.
10. QM > 116% If mast torque (QM) exceeds 116%, the highest accumulated exceedance
time within any 60 minute period, since last cleared, will be displayed.
11. QM > 103% If mast torque (QM) exceeds 103%, the highest accumulated exceedance
time within any 60 minute period, since last cleared, will be displayed.
12. MODIFY QM > 125% Pressing L-4 displays the cursor next to the L-4 legend allowing the operator
to enter a number between 0 - 99 for the QM > 125% counter. After pressing
the ENTER key on the MFK, the number is displayed next to the text # OF
COUNTS IN XMSN LIFE. If an invalid entry is made, the entry is blanked,
the cursor reappears and the text ERR is displayed.
13. QE > 131% If engine torque (QE) exceeds 131%, time above the limit is displayed along
with peak QE.
14. NP > MAX Two set point limits for power turbine speed (NP) vary according to engine
torque. Normal operating conditions for NP are below both limits. If the
upper limit is exceeded, then the NP percentage is displayed.
15. NG > 106 If turbine gas generator speed (NG) exceeds 106%, time above that limit is
displayed along with peak percentage NG above the upper limits.
16. TGT > 905 If TGT exceeds 905 °C, time above that limit is displayed along with the
peak TGT.

CONTROL/INDICATOR FUNCTION
1. MAINTENANCE CODES Provides a hexadecimal representation of six Engine Status Words (ESW).
Each ESW is presented as a four-character (alphanumeric) word in
hexadecimal format (Example: 0C30). These maintenance codes are stored
in memory and are shown each time ENGINE HISTORY Page 3 is displayed
until the maintenance codes are either cleared using CLEAR on ENGINE
HISTORY Page 1 or the engine is started.
2. MODIFY ENG STARTS Pressing the L-4 bezel displays the cursor next to the L-4 legend. This
allows the operator to enter a number (0 to 9999) for the engine starts. After
pressing enter on the keyboard, the number is displayed next to the text
ENG STARTS. If an invalid entry is made, the entry is blanked, the cursor
reappears and the text ERR is displayed.
3. ENG STARTS This event counter is incremented by one for each attempted engine start.
4. LIMIT ORIDES This event counter is incremented once each time an engine limit is
overridden.
5. AUTO RESTART This event counter is incremented once each time an automatic engine
restart occurs.

6. OS EVENTS This event counter is incremented once for each engine overspeed event.
7. MANUAL DEFAULTS This event counter is incremented once each time the FADEC system enters
the manual mode.

CONTROL/INDICATOR FUNCTION
1. TGT START Maximum turbine gas temperature during an engine start, including aborted
starts, is displayed in degrees Celsius.
2. TGT RUN Maximum turbine gas temperature during regular running conditions and the
time above the lower limit (716 °C) is displayed if TGT exceeds 767.8 °C.
Otherwise, only the maximum TGT is displayed.
3. NG Peak turbine gas generator speed (NG) (highest value since last clearing) is
displayed as a percentage. If the NG exceeds 106%, time above the limit is
displayed in seconds. Otherwise, the time is not displayed.
4. NP Two setpoint limits for power turbine speed (NP) vary according to engine
