5.1.3 Course Deviation Indicator
The course deviation information must be located in the Pilot's Primary Field of view if the
IFD5XX is used for IFR navigation. Installation of a CDI/HSI requires a separate installation
approval.
5.1.4 Instrument Panel Cutout
The IFD5XX tray is designed to be installed on the backside of the instrument panel. The
instrument panel requires a 6.320" x 4.600" hole in the instrument panel for the IFD5XX unit
to slide through, reference Figure 8. If the instrument panel in the aircraft is considered
primary structure, additional installation approval will be required for the instrument panel
cutout. The installer is responsible to ensure the structural aspects of this installation meet the
requirements of AC 43.13-2B, Chapter 11, Paragraph 1104(a).
5.1.5 Requirements for Tray Installation
The Avidyne Tray must be installed in the aircraft as described below in order to satisfy the
structural requirements for the STC. Deviations to these requirements will require separate
approval.
1.
Rear Tray Support (Instrument Panel)
a.
The existing instrument panel must be fabricated from 2024-
T3 aluminum with a minimum thickness of 0.050". The tray
brackets must be fabricated from 3/4" x 3/4" x 1/16" 2024-T3
aluminum angle extrusion for mounting the tray, as shown
in Figure C - 33.
b.
If new components are fabricated, the fabrication methods
must follow the requirements of FAA Advisory Circular
43.13-1B, Chapter 4 for general airframe fabrication criteria,
including hole tolerances, edge distances, rivet spacing, and
corrosion protection, and Advisory Circular 43.13-2B
Chapters 2 and 11 for structural adequacy.
2.
Forward Tray Support
a.
The Avidyne Tray must have forward support brackets,
reference Figure C - 33. The forward support brace must be
0.032” 5052-H32 aluminum. (Note: equivalent or stronger is
acceptable)
b.
If new forward support brackets are fabricated and, the
fabrication methods must follow the requirements of Figure
C - 33, FAA Advisory Circular 43.13-1B, Chapter 4 for
general airframe fabrication criteria, including hole
tolerances, edge distances, rivet spacing, and corrosion
protection, and Advisory Circular 43.13-2B, Chapters 2 and
11 for structural adequacy.
The IFD5XX should be installed using six #6-32 flat head screws and self locking nuts. Figure
C - 33 shows installation.
