The Approved Model List for the STC will indicate if an aircraft is required to install wire harness
overbraid on the AeroNav XXX wiring. Note: Overbraid is not required on VFR only installations as
defined in Section 2.4.1.
4.5.3 Copper Overbraid Installation
The copper overbraid, if required, must be a minimum 90% optical coverage per ASTM-B-33. The
overbraid must be grounded at both ends. If the aircraft wiring passes through wire disconnects or
bulkheads, the overbraid should be continued on each segment.
The wire harness overbraid should also be installed per FAA AC 43.13-1B Chapter 11-189.

4.7 Byteflight Digital Data Bus Consideration – Dual AeroNav Installations
Dual AeroNav installations use a Byteflight digital Databus protocol when connected via RS-232
Channel 3 and configured for CrossSync. The following must be considered for replacement and new
installations.
4.7.1 Databus Wiring - Replacement Installations
For installations that are replacing two previously connected GNS4xx/5xx systems, the Byteflight
digital Databus is capable of using the pre-existing wiring between the two pre-existing trays with no
additional wiring or modifications required. All bus termination is built into the AeroNav units.
However, the existing wire length on the CrossSync connection must not exceed 8 feet in length on
AeroNav XXX RS-232 Channel 3 on P1001. Installations with longer installation lengths between
AeroNav XXX units must use Byteflight cable. The ByteFlight wire is available from Avidyne, reference
Table 29.
Installations with significant amount of Byteflight data interruptions should consider installing
Byteflight cable.
