2. G. (8) (a) Bleed Air Pressure Digital Readouts (RBLEED/LBLEED AIR) - The
RBLEED AIR and LBLEED AIR digital readouts comprise the first
row of displays on the ENGINE START display
page. The white
digital readouts are readable to a 1 PSI resolution.
(b) Fuel Pressure Low Annunciations - The LFUEL PRESS LOW
annunciation is located in the box directly below the left
bleed air pressure digital readout. The RFUEL PRESS LOW
annunciation is located in the box directly below the right
bleed air pressure digital readout. These annunciations are
displayed when a fuel pressure low condition is detected.
(c) Start Valve Open (SVO) Annunciation - The SVO annunciations
are located in the third row of data. The first box houses the
L SVO annunciation while the third box houses the R SVO
annunciation.
The SVO annunciation changes color in
relationship to HP9ARPM as described in paragraph 2.E.(2)
(primary engine instruments).
(d) Ignition (IGN) Annunciation - The green IGN annunciations are
located in the third row of data. The second box houses the
L IGN annunciation while the fourth box houses R IGN
annunciation.
(e) Left Turbine Gas Temperature (L TGT) Display - The L TGT s~~~~
is the first scale in the (fourth) row of analog scales. “
display is a low end expansion of the TGT round dial gauge on
the primary engine instruments. The white scale is marked
every 100 “C and ranges between 100 and 700 “C. A set-point
triangular mark is shown at 425 “C. A white label L TGT
appears at the scale bottom. The data display pointer is a
moving ladder type thermometer. As the TGT value increases,
the thermometer grows
up the scale. A ladder rung is left at
each labeled tickmark. The normally white thermometer turns
red for TGT values greater than 700 “C.
(f) Right Turbine Gas Temperature (R TGT) Display - The RTGT scale
is the third scale in the (fourth) row of analog scales. This
display is a low end expansion of the TGT round dial gauge on
the primary engine instruments. The white scale is marked
every 100 ‘C and ranges between 100 and 700 ‘C. A set-point
triangular mark is shown at 425 “C. A white label RTGT
appears at the scale bottom.
The data display pointer is a
moving ladder type thermometer. As the TGT value
increases,
the thermometer grows up the scale. A ladder rung is left at
each labeled tickmark.
The normally white thermometer turns
