CESSNA SECTION 7
MODEL 208B G1000 AIRPLANE AND SYSTEMS DESCRIPTION
TORQUE INDICATIONS
Torque (TRQ) indication is displayed at the top of both the ENGINE and
SYSTEM pages. The indicator is a round gage with a white pointer. The
transmitter senses the difference between the engine torque pressure
and the pressure in the engine case and transmits this data to the
G1000. Normal operating range is indicated by a green arc that
extends from 0 to redline. Redline varies from 1865 to 1970 ft-lbs
depending on prop RPM.
For normal cruise flight when prop RPM is between 1600-1900, a blue
torque “bug” is included on the arc. This indicates maximum allowed
cruise torque per the cruise performance and maximum torque charts
in section 5, Performance. The blue advisory cruise torque bug located
on the EIS torque indication is not to be used as the primary means of
setting cruise torque. Always refer to the appropriate performance chart
in Section 5 of the POH/AFM.
PROPELLER RPM INDICATIONS
The propeller RPM (PROP RPM) is indicated numerically below Gas
Generator RPM. The digits are white with RPM between 0-1599 RPM,
green between 1600-1900 RPM, and white with a red background
when RPM is greater than or equal to 1910. The instrument is
electrically operated from the propeller tachometer-generator which is
mounted on the right side of the front case.
ITT INDICATION
Interstage Turbine Temperature (ITT) is indicated below torque and is
round dial gage with a white pointer. This instrument displays gas
temperature between the compressor and power turbines. With the
engine off or during start ITT indicator displays a green band from
100°C to 740°C, an Amber caution band from 766°C-805°C and a
redline at 1090°C. The gage is graduated at 100 degree intervals from
600°C to 1100°C.
With the engine running a green arc indicates normal operating range
from 100°C to 740°C, an Amber caution region from 765°C-805°C with
a redline at 805°C. The gage is graduated at 50 degree intervals from
600°C-900°C. The digital readout flashes red when an overtemperature
situation has occurred.
GAS GENERATOR RPM INDICATIONS
Gas generator RPM (N g) is displayed below ITT using a round dial
gage with a white pointer. RPM is displayed as a percentage of
maximum gas generator RPM. The instrument is electrically operated
from the gas generator tachometer-generator mounted on the lower
right portion of the accessory case. The gage has tick marks at 0, 12,
50, and 105% with a redline at 101.6%.
