Altimeter (Standby Instrument Panel) - Cessna Grand Caravan 208B G1000 Manual

SECTION 7 CESSNA
AIRPLANE AND SYSTEMS DESCRIPTION MODEL 208B G1000
AIRSPEED INDICATIORS
The Garmin PFDs are the primary sources of airspeed information.
Standby airspeed information is depicted by a mechanical indicator
calibrated in knots, connected to the left pitot-static system. Limitation
and range markings (in KIAS) match the markings on the PFD as listed
in Section 2, Limitations.
The standby airspeed indicator is a true airspeed indicator and is
equipped with a knob which works in conjunction with the airspeed
indicator dial in a manner similar to the operation of a flight computer.
To operate the indicator, first rotate the knob until pressure altitude is
aligned with outside air temperature in degrees Centigrade. To obtain
pressure altitude, momentarily set the barometric scale on the altimeter
to 29.92 and read pressure altitude on the altimeter. Be sure to return
the altimeter barometric scale to the original barometric setting after
pressure altitude has been obtained. Having set the knob to correct for
altitude and temperature, read the true airspeed shown in the window
by the indicator pointer. For best accuracy, the indicated airspeed
should be corrected to calibrated airspeed by referring to the Airspeed
Calibration chart in Section 5, Performance. Knowing the calibrated
airspeed, read true airspeed in the window opposite the calibrated
airspeed.
VERTICAL SPEED INDICATION
The vertical speed indication on the PFDs depict airplane rate of climb
or descent in feet per minute. The pointers are actuated by atmospheric
pressure changes resulting from changes of altitude as supplied by the
static sources.

ALTIMETER (STANDBY INSTRUMENT PANEL)

Airplane altitude is depicted by a barometric type altimeter. A knob near
the lower left portion of the indicator provides adjustment of the
instrument's barometric scale to the current altimeter setting.
