Note: It is imperative that only one source of terrain cautions and warnings be enabled on the airplane so
as to avoid the potential for conflicting information to be presented to the pilot. If a TAWS system is
installed but the IFD's internal TA and FLTA functions are to be used for terrain avoidance, the TAWS
system must be fully disabled. If a TAWS system is to be used, its type must be properly configured on the
IFD so that the caution and warning indications generated by the TAWS system can be displayed to the
pilot and so that the IFD's TA and FLTA functions will be inhibited.
Avidyne TA/FLTA is not an approved TSO-C151 EGPWS unit.
The IFD system supports a Honeywell KGP560/860 system only. All other external TAWS/EGPWS
systems must be disabled if the internal TA and FLTA is operational on the IFD system.

Table 68: Aircraft Fuel Type
In GPS mode on the IFD5XX, the GPS Select discrete will not be
active (open) in a GPS approach, and no messages will annunciate
on the IFD5XX and no pilot action is required. This setting allows
the pilot to use the GPS  VLOC Capture option on the User
Options part of the Setup tab on the AUX page.
In GPS mode, the user will be prompted to enable the approach in
KAP140 and KFC225 equipped aircraft. When Prompt is selected,
and a GPS approach mode is active, a CAS message will prompt
the pilot to "Enable A/P Approach" on the FPL tab. At that point,
the pilot may then enter APR mode on the autopilot. This setting
will also ignore the GPS  VLOC Capture option on the User
Options part of the Setup tab on the AUX page.

Select if an external EGPWS or TAWS device (e.g. KGP 560) is
connected to the IFD5XX. This will enable the IFD5XX to send
position data to the device and it will disable FLTA and TA
functionality as well as aural alerts in the IFD5XX
Select when no external EGPWS or TAWS device is connected to
the IFD5XX, thereby enabling all FLTA and TA functionality on the
IFD5XX.
