2.8 AHRS Normal Operating Mode
The Attitude and Heading Reference System integrity monitoring function
requires GPS and Air Data to be provided to the AHRS. Note: Attitude will
remain valid if one of these systems becomes inoperative.
Flight in IMC is not authorized unless the AHRS is receiving valid GPS and
valid Air Data. The G500/G600 monitors these integrity systems automatically
and will alert the pilot when the AHRS is not receiving GPS or Air Data.
Note: In dual GPS installations, only one GPS needs to be available to the
AHRS for IFR flight.
2.9 Airspeed Limitations and Indicator Markings
The original type design approved airspeed limitations remain in effect. The
airspeed limitations stated in the AFM/POH, standby airspeed indicator and/or
airspeed limitation placards must be observed.
The G500/G600 airspeed tape displays red/white striping to indicate the
maximum allowable airspeed (V
NE
/V
MO
/M
MO
). This maximum allowable
airspeed display is configured to indicate the appropriate maximum allowable
airspeed for the airplane, including variations for altitude or Mach number.
The G500/G600 airspeed tape displays a red low-speed awareness band at the
lower range of the airspeed tape. This low-speed awareness band is configured
to a fixed value. It does not indicate an actual or calculated stall speed and does
not adjust with variations in aircraft weight or other factors.
All other G600 airspeed tape indications are configured to indicate the original
type design limitations. The G500/G600 airspeed tape does not adjust these
additional markings (including V
NO
, landing gear, or flap speed limitations) for
variations with aircraft weight, altitude, or other factors.
2.10 Aerobatic Maneuvers
Do not conduct aerobatic maneuvers if uninterrupted attitude information is
required on the PFD.
2.11 Course Pointer Auto Slewing
The G500/G600 HSI will auto slew, i.e. automatically rotate the GPS course
pointer to the desired course defined by each GPS leg. The system will also auto
slew the VHF NAV course pointer when the CDI transitions to a LOC setting if
an ILS, LOC, LOC BC, LDA, or SDF approach is loaded in the GPS/SBAS
navigator.
The VHF NAV (green) course pointer will only auto slew if the approach is
loaded in the navigator, a LOC frequency is loaded in the active NAV frequency,
and then the HSI source is changed to the corresponding VHF NAV for the
approach. Back Course approaches will auto slew to the reciprocal course.
