2. E. (3) Secondary Engine Instruments
(a) Engine Oil Pressure (OIL PRESS) Display - The engine oil
pressure is displayed digitally in white in the first row of
the secondary engine parameters (Figure 223). The resolution
of the readout is 1 PSI. The display digits change color as a
function of oil pressure as defined below:
RED O PSI < OIL PRESS < 16 PSI
AMBER
16 PSI ~ OIL PRESS < 30 PSI
WHITE
30 PSI ~ OIL PRESS
(b)
Engine Oil Temperature (OIL TEMP) Display - The engine oil
temperature is displayed digitally
in white in the second row
of the secondary engine parameter display (Figure 223). The
resolution of the digital readout is 1 “C. The display digits
change color as a function of oil temperature as defined below:
RED
OILTEMP < -40 “C
AMBER
-40 “C < OIL TEMP < -30 “C
WHITE
-30 “C ~ OIL TEMP < 105 ‘C
AMBER
105 “C < OIL TEMP < 120 ‘C
RED
120 “C < OIL TEMP
(c) Engine Vibration Monitor (EVM) Display - The EVM displays
(Figure 223) consists of two sets of windows (row 3 and 4)
labeled LP and HP respectively. EVM is displayed digitally in
white to a 0.01 IPS resolution.
(d) Combined Hydraulic Pressure (FLT HYD PRESS) - The COMB HYD
PRESS
digital readout is the left-most display in the fifth row
of the secondary engine parameter display (Figure 223).
COMB
HYD PRESS is displayed digitally in white to a 1OO-PSI
resolution.
(e) F1ight Hydraulic Pressure (FLT HYD PRESS) - The FLT HYD PRESS
digital readout is located right of the COMB HYD PRESS display
in the fifth row of the secondary engine parameter display
(Figure 223).
FLT
HYD PRESS is displayed digitally in white to
a 1OO-PSI resolution.
