GARMIN G1000
PITOT-STATIC SYSTEM AND INSTRUMENTS

AIRSPEED INDICATORS

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 standby
altimeter to 29.92 and read pressure altitude on the standby altimeter.
Be sure to return the standby 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 through the respective ADC.

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.
