Footnotes:
(1) The maximum transient torque value is 2750 ft-lb for up to 5 seconds. Within this transient
value, the torque indicator will display green digits and a white pointer. After 5 seconds, the digits
will flash alternating red and white background with a flashing red pointer for 5 seconds. After 5
seconds of flashing, the indication is steady white digits/red background and the pointer is red.
Above 2750 FT-LB, the indication immediately begins flashing for 5 seconds before displaying
steady white digits on a red background and a red pointer.
(2) A red diamond at 1000°C represents the upper transient limit for engine Starting Mode. The
lower Normal Mode transient limit is 850°C. Within this transient value, the ITT indicator will
display green digits and a white pointer. After 20 seconds between 820
°
C and 850
°
C (or above
1000°C for more than 5 seconds in Starting Mode), the ITT digital indication will flash alternating
red and white background with a flashing red pointer for 5 seconds. After 5 seconds of flashing,
the indication is steady white digits/red background and the pointer is red. In Normal Mode while
above 850
°
C, the indication immediately begins flashing for 5 seconds before displaying steady
white digits on a red background and a red pointer.
(3) See PROPELLER TYPES AND INDICATOR MARKINGS table.
(4) Above 104%, the digital indication will flash alternating red and white background with a flashing
red pointer for 5 seconds. After 5 seconds of flashing, the indication is steady white digits/red
background and the pointer is red
(5) Above 110°C, the digital indication will flash alternating red and white background with a
flashing red pointer for 5 seconds. After 5 seconds of flashing, the indication is steady white
digits/red background and the pointer is red. Below 0°C to -40°C, the digital indication will be
black digits on a yellow background. Below -40°C, the digital indication will be white digits on a
red background.
(6) Above 135 PSI, or below 60 PSI and decreasing oil pressure, the digital indication will flash
alternating red and white background with a flashing red pointer for 5 seconds. After 5 seconds
of flashing, the indication is steady white digits/red background and the pointer is red.
(7) A red diamond at 200 psi represents the upper transient limit.
