Revision: 02
5. Mechanical Installation
This section will describe the physical mounting of the IFD5XX in the aircraft.
Aircraft installing the IFD5XX for VFR use only, as defined in Section 2.4.1, can install the
IFD5XX unit in any location easily accessible to the pilot. However, the IFD5XX installation
must not introduce any new hazards. All other installations must follow the guidance below.
5.1 Equipment Location
– New Installations
If the IFD5XX is used for IFR navigation, course deviation information and navigation
annunciation must be installed in the Pilot’s Field of View (FOV). The FAA has provided
clarification regarding the intent of TSO-C146 and acceptable source annunciation location,
navigation annunciation, and FOV requirements on similar products in the past. Therefore,
the installation data as follows must be followed to maintain compliance with the STC.
Otherwise, additional installation approval will be required.
Aircraft requiring two pilots must have this annunciation at each pilot station or
unobstructed view of the IFD5XX display. The IFD5XX should be located in a position easily
reached by both pilots.
5.1.1 Determining the Field of View
The navigation source selection field of view is approximately ±30° or 13.856" horizontally
from the center of the attitude indicator, or centerline of the pilot's seat/yoke. The navigation
annunciation field of view is approximately ±35° or 16.805" horizontally from the center of
the attitude indicator. Both of these angles and distances are determined with the pilot seated
at a minimum of 24" from the instrument panel.
The vertical field of view will be from the top of the instrument panel to the portion of the
instrument panel that is immediately below the basic 'T' instruments, reference Figure 8.
Note, if the existing type certified HSI/CDI/PFD is lower than the basic 'T', use that as the
lower limit.
Figure 8 below indicates the acceptable field of view for the IFD5XX. If the IFD5XX can be
installed in this area, remote navigation annunciation is not required. If the IFD5XX cannot be
installed within the acceptable field of view, the installation must have navigation
annunciations installed per Section 5.1.2.
