AIRPLANE AND SYSTEMS DESCRIPTION
MODEL 172S NAV III
CLOCK / O.A.T. INDICATOR
A numerical time or clock window (based on GPS time) and an
outside air temperature (O.A.T.) indicator window are provided along
the lower edge of the PFD. The O.A.T. indicator uses an air
temperature sensor located on top of the cabin.
STALL WARNING SYSTEM
The airplane is equipped with a pneumatic type stall warning
system consisting of an inlet in the leading edge of the left wing, an
air-operated horn near the upper left corner of the windshield, and
associated plumbing. As the airplane approaches a stall, the low
pressure on the upper surface of the wings moves forward around
the leading edge of the wings. This low pressure creates a
differential pressure in the stall warning system which draws air
through the warning horn, resulting in an audible warning at 5 to 10
knots above stall in all flight conditions.
STANDARD AVIONICS
The Garmin G1000 Avionics System is an integrated flight control
and navigation system. The system combines primary flight
instruments, communications, aircraft system information and
navigational information all displayed on two color displays. The
G1000 system consists of the following pieces of equipment:
GDU 1040 COLOR DISPLAY
Two identical units are mounted on the instrument panel. One,
located in front of the pilot, is configured as a Primary Flight
Display, or PFD. A second panel, located to the right, is configured
as a Multi-Function Display, or MFD.
The PFD displays roll and pitch information, heading and course
navigation information, plus altitude, airspeed and vertical speed
information to the pilot. The PFD also controls and displays all
communication and navigation frequencies as well as displaying
warning/status annunciations of aircraft systems.
