97-60 Avionics Software
Modern avionics software is complex and subject to rigorous testing by RHC to assure proper
function and integration in the aircraft. Only specified software versions and software
configurations have been FAA-approved for installation in Robinson helicopters. Software
updates should not be attempted without a thorough understanding of approval status and
compatibility. Technical support from either RHC or the avionics manufacturer will likely be
required. In some cases, updating software for one item of avionics may require additional
avionics to be updated to assure compatibility.
As long as RHC-installed equipment is functioning properly, there is no continuing
airworthiness requirement to check or update software levels in Robinson helicopters; RHC
will issue an SB (or FAA will issue an AD) for any mandatory updates.

Software page for approved software configurations.
NOTE
The above statements apply to avionics operating software.
Databases (e.g. charts, terrain, etc.) may be updated regularly
using avionics manufacturer’s recommended procedures.
