FLIGHT INSTRUMENTS
G1000 FLIGHT INSTRUMENTS
Flight instruments are an integrated part of the G1000 system. For system descriptions, operating
instructions, and abnormal failure indication refer to the Cockpit Reference and Pilot’s Guides.
STANDBY FLIGHT INSTRUMENTS
There are three 2 ¼ inch standby instruments that are arranged vertically
directly to the right of the pilot’s Primary Flight Display:
• Standby attitude indicator
• Standby altimeter
• Standby airspeed indicator
The standby attitude indicator located at the top of the stack is normally
powered by the standby instrument bus, which receives power from the
isolation bus. In the event of total loss of electrical power, there is a
standby battery that will power the standby attitude indicator for at least
30 minutes.
The second instrument in the stack is a standby altimeter. It is a
mechanical instrument that requires no electrical power to display altitude.
Electrical power is used for internal instrument lighting, and for an internal
vibrator that is used to minimize indicator pointer sticking. The vibrator
is normally powered from the standby instrument bus. In the event of
total loss of normal electrical power, the vibrator and internal lighting are
powered by the standby battery. The standby altimeter uses the
copilot’s static system for its source of static air pressure.
The bottom instrument is a mechanical airspeed indicator. It is a
mechanical instrument that requires no electrical power to operate.
Electrical power is used for internal lighting. In normal operation, power
for standby instrument lighting comes from dual feed bus 1. In the event
of a total loss of electrical power, the standby battery will power the
instrument’s internal lighting. The standby airspeed indicator uses the
copilot’s static system for its source of static air pressure, and the
copilot’s pitot system for its source of impact air pressure.
