mode is selected on the autopilot. As another
example, some autopilots such as the KAP-140 and
the KFC 225 do not support automatic switching to
VLOC; switching the nav mode and entering the in-
bound course must be manual operations with those
autopilots.
In the case of KFC-225 and KAP-140 autopilots,
depending on how the IFD was configured, a
prompt is provided when GPS is the nav source to
enable the approach (“Enable A/P Approach” CAS
message displayed which directs a pilot selection
along the left side of the FPL tab). At that point,
APPR mode can then be selected 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.
RNP/RNAV OPERATIONS
The IFD540 complies with the equipment requirements of AC 90-
105 and meets the equipment performance and functional
requirements to conduct RNP terminal departure and arrival
procedures and RNP approach procedures without RF (radius to
fix) legs. Part 91 subpart K, 121, 125, 129, and 135 operators
require operational approval.
The IFD540 installed with an SBAS approved antenna, provides
pilot and automatic flight control guidance for the following
operations conducted under instrument flight rules (IFR):
•
VOR, LOC, ILS instrument approach procedures
(procedures using VHF radio guidance)
•
RNP instrument approach procedures using the
following lines of minima:
o
LNAV minima (including when using advisory
vertical guidance from the system);
o
LNAV/VNAV minima;
o
LPV minima; and
o
LP minima.
