pressing the ADVISORY softkey. A warning annunciation requires immediate
corrective action and threatens the continued ight of the aircraft.

FUEL OFF L-R
Warns the pilot that both fuel selector valves are in the OFF
position. A red LED light located above the pilot’s PFD will also
illuminate and remain illuminated until one or both fuel selector
valves are returned to the ON position.
OVERSPD WARN
Warns the pilot that Vmo has been exceeded. The overspeed
warning limits are 182 KIAS with an increasing airspeed and 181
KIAS with decreasing airspeed.
CARGO DOOR
Warns the pilot that the cargo door is not fully closed while the
aircraft is in the air with a groundspeed of at least 30 knots (GPS)
or airspeed of at least 50 knots (TAS).
RESERVOIR FUEL

starvation is imminent.
CHIP DETECTOR
Warns the pilot that a metallic chip has been detected in the
