INSTRUMENTS SWITCH
The standby flight instruments switch is in the
AVIONICS section of the left lower instrument
panel and has three positions: STBY
INST, OFF, and BATT TEST (Figure 16-4).
When the switch is in the STBY INST position,
it provides DC power (from a backup battery)
to the standby flight instruments on the upper
center instrument panel:
• Airspeed indicator
• Attitude gyro
• Altimeter
A small amber light emitting diode (LED) on
the right side of the switch illuminates when
in the STBY INST position, indicating the
standby flight instruments are discharging
power from the dedicated standby lead-acid
battery pack. A fully charged battery supplies
power for approximately 30 minutes. The
amber light does not illuminate when aircraft
power is charging the battery and providing
power to the standby instruments.
In the BATT TEST position, the condition of the
backup battery is tested. Illumination of the
green light beside the switch indicates proper
battery charge. If the green light does not illuminate,
the backup battery is not properly
charged, and standby flight instruments may
not operate with the loss of normal DC power.
PRIMARY FLIGHT
DISPLAY
DESCRIPTION
The main control display units for the G1000
are the PFDs. The Citation Mustang has two
PFDs, one in front of the pilot and one in front
of the copilot (Figure 16-5).
The PFDs are 10.4-inch color LCDs, which
are designed for visibility in bright sunlight.

Display Color-Coding
Color-coding on the displays indicates common
meanings to the pilot. These colors and
their meanings are:
• Cyan—Pilot adjustable
• Green—Active
• White—Armed/standby
• Amber—Caution
• Red—Warning
• Magenta—GPS derived
GRAPHICAL FLIGHT
INSTRUMENTATION
The following flight instruments are depicted
graphically on the PFD:
• Airspeed display
• Altitude
• Attitude display including turn coordination
(slip/skid)
• Horizontal situation indicator (HSI)
(heading, turn rate, and radio navigation)
• Vertical speed
NOTE
If the aircraft exceeds normal flight
attitudes (30° nose-up or 20° nosedown
pitch, or roll greater than 65°
bank), the PFD declutters leaving
the primary flight instruments.
Airspeed Display
The airspeed is displayed as a vertical scale
on the left side of the PFD (Figure 16-6).
Moving Tape Display Box
White numerals and tick marks on a transparent
rolling-tape display box indicate airspeeds
currently above and below the current airspeed.
Each small tick mark represents 5 knots,
and each large tick mark (with a number) represents
10 knots.
Airspeed Pointer
The airspeed (in KIAS) appears as a rolling numeric
display (white numbers on black) in the
center of the airspeed tape. This tape has a
pointer, which always points at the center of
the airspeed display. Below 20 KIAS, the digits
change to dashes. Once the airspeed reaches
and/or exceeds VMO or MMO, the pointer
changes to red with white numbers.
Trend Vector
On the outside right edge of the tape, a magenta
trend vector indicates predicted airspeed
in 6 seconds at the current rate of
airspeed acceleration. When the trend vector
enters the barber pole range, the numbers inside
the airspeed pointer change from white
to amber.
Speed Awareness
Airspeeds above the maximum operating speed
appear in the high-speed awareness range represented
