3. EMERGENCY PROCEDURES
3.1 Emergency Procedures
No change.
3.2 Abnormal Procedures
These procedures supersede those presented as markings or placards, or documented
in the aircraft’s TCCA/FAA approved AFM as a result of the installation of the G500
PFD/MFD system. All other emergency procedures remain in effect.
1. If primary flight information (Heading, Altitude or Airspeed) on the PFD is not
available or appears invalid, utilize the standby instruments installed around and
adjacent to the G500, as required.
2. The AHRS requires at least one GPS or air data input to function properly. In the
unlikely event that GPS data or air data is not received by the AHRS, the system
will subsequently lose attitude and heading and the pilot will be required to use
the standby instrumentation. In this instance, the PFD will not provide Attitude,
Heading, Altitude, or Airspeed information; however, if the PFD is receiving valid
GPS information, the reversionary data on the PFD provides GPS track and GPS
Altitude data along with course information and deviations which are still valid
and may be used to navigate.
3. If navigation information on the PFD/MFD (HSI, RMI, WPT bearing and distance
information, or Moving Map Data) is not available or appears invalid, select an
alternate source (via CDI key or 1-2 key) or utilize the data directly from the
navigation equipment as required.
4. If any of the data sources from SVT become unreliable or unavailable, the
display of synthetic terrain will automatically revert to the non-SVT PFD display of
blue over brown. Additionally, if during the course of normal operations there is
any discrepancy between actual terrain around the aircraft and terrain shown on
the SVT display, the display of synthetic vision should be manually turned off
using the procedure in paragraph 4.3 of this supplement.
5. If GPS position information from the GNS430W is not valid due to an inability to
track GPS, the own-ship icon on the MFD is removed and “NO GPS POSITION”
text is overlaid on the MFD moving map. The system will annunciate a loss of
integrity, “LOI” on the HSI. The LOI annunciation will be colored yellow and the
HSI needle will flag. The pilot should select an alternate navigation source (via
CDI key or 1-2 key). Pressing the CDI soft key will change the HSI navigation
source. If GPS navigation is subsequently restored, the MFD moving map will
display the own-ship icon, and the HIS navigation source may be selected to
GPS; at that time the LOI annunciation will be removed.
