torque. Normal NP operating conditions are below both limits. If the lower of
the two limits is exceeded for more than 10 seconds, peak NP is displayed
as a percentage. If both lower and upper limits are exceeded, the
percentage and time above the upper limit is displayed in seconds.
5. NR Peak main rotor speed is displayed at all times as a percentage.
6. MAST TRQ Peak transmission mast torque (MAST TRQ) (highest since last clearing) is
displayed as a percentage. Time (seconds) is displayed only if above the

1. TGT START Maximum turbine gas temperature (TGT) during an engine start, including
aborted starts, is displayed in degrees Celsius.
2. TGT RUN Maximum turbine gas temperature (TGT) 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
torque. Normal NP operating conditions are below both limits. If the lower of
the two limits is exceeded for more than 15 seconds, or if upper limit is
exceeded, then NP is displayed as a percentage along with the time in seconds
spent above the lower limit.
5. NR Peak main rotor speed (NR) is displayed at all times as a percentage.
6. MAST TRQ Peak transmission mast torque (MAST TRQ) (highest since last clearing) is
displayed as a percentage. Time (seconds) is displayed only if above the limit
(103%).

7. ENG TRQ Peak engine output torque (ENG TRQ) (highest since last clearing) is displayed
as a percentage. If ENG TRQ exceeds 131%, the time above the limit is
displayed in seconds.
8. ENG SURGE This event counter monitors the number of engine surge events. The counter
increments each time a latched surge event indication occurs. The counter
does not increment for engine surges which occur subsequent to a latched
surge event indication unless the latched indication has been reset either by
power down of the ECU or transition from manual to auto mode.
9. FADEC DEGRADE - Activation of this advisory occurs when the FADEC system has detected a fault
DROOP that will result in possible rotor droop.
10. FADEC DEGRADE - OS Activation of this advisory occurs when the FADEC system has detected a fault
that results in a loss of the FADEC OVERSPEED limiting system.
11. FADEC DEGRADE - Activation of this advisory occurs when the CDS determines a problem with the
ARINC ARINC communication bus. This message is an indication that the CDS or
FADEC system has detected a loss of the ARINC bus.
12. FADEC TRQ LIM LOSS Activation of this advisory occurs when the FADEC system has detected a fault
that results in a loss of the FADEC engine torque limiting feature.
13. FADEC TGT LIM LOSS Activation of this advisory occurs when the FADEC system has detected a fault
that results in a loss of the FADEC TGT limiting feature.
