PRODUCT DATA JANUARY 2003
“HYD OIL” or “HYD 2” (System 2)
“GEN” or “GEN 2” (Generator 2)
This advisory appears above the engine 1
torque display on the primary screen.
This caution appears when a faulty or
unreliable D.C. power source from the
engine 2 mounted starter/generator is
detected by the No.2 voltage regulator. This
caution uses the generator 2 voltmeter/
ammeter label as the annunciator by turning
it amber and flashing or as “GEN 2” in the
W/C/A window when on page 1. When both
generators are failed, the amber caution
changes to red warning.
“HYD OIL” or “1 HYD” (System 1)
This caution, appears when system 1
hydraulic press decreases below 1000 psia.
This caution uses the system 1 hydraulic
oil pressure/temperature label as the
annunciator by turning it amber and flashing
or as “1 HYD” in the W/C/A window when
on page 1 or on the start page.
This caution, appears when system 2
hydraulic pressure decreases below 1000
psia. This caution uses the system 2
hydraulic oil press/temperature label as the
annunciator by turning it amber and flashing
or as “HYD 2” in the W/C/A window when
on page 1 or on the start page.
This white advisory appears when engine
1 FADEC/ECU sends its degraded mode
signal over the ARINC 429 data bus. This
advisory is enabled whenever a sensor
failure will reduce the FADEC/ECU
response capabilities such as:
1. ARINC 429 data bus failure
2. Nr beep fault
3. MGT sensor fault
4. Torque sensor fault
5. Nr sensor fault
“ECU” (Engine 1)
“ECU” (Engine 2)
“2 MIN OEI” (Engine 1)
This caution appears when the engine 2
FADEC/ECU sends its 2 minute OEI signal
over the ARINC 429 data bus. This advisory
appears on the top right hand side of the
primary screen. In conjunction with this
“2 MIN OEI” (Engine 2)
This caution appears when the engine 1
FADEC/ECU sends it 2 minute OEI signal
over the ARINC 429 data bus. This advisory
appears on the top left hand side of the
primary screen. In conjunction with this
caution the engine 1 MGT and torque scale
change their limit. This caution does not
trigger the attention-getter. A flashing down
counter is also provided on the left hand
side of the No.1 MGT scale to indicate the
last ten seconds of the OEI event. In the
event that the ARINC 429 input becomes
invalid, the IIDS will trigger this caution
based on the parameter input.
This white advisory appears when engine
2 FADEC/ECU sends its degraded mode
signal over the ARINC 429 data bus. This
advisory is enabled whenever a sensor
failure will reduce the FADEC/ECU
response capabilities such as:
1. ARINC 429 data bus failure
2. Nr beep fault
3. MGT sensor fault
4. Torque sensor fault
5. Nr sensor fault
This advisory appears above the engine 2
torque display on the primary screen.
