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. Normally,
the ITT indicator will display green digits and a white pointer. Above 800°C, or when between
750°C and 800°C for more than 5 seconds, (or above 1000°C for more than 5 seconds in Starting
Mode), 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.
(3) See PROPELLER TYPES AND INDICATOR MARKINGS table.
(4) The maximum transient N1 value is 102.6% for up to 10 seconds. Within this transient value, the
N1 indicator will display green digits and a white pointer. When between 101.5% and 102.6% for
more than 10 seconds, or when above 102.6%, 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 104°C, or between 99°C and 104°C for more than 5 minutes, 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.
