Aircraft with VDR Deafness Update Installed
There are many causes of provider aborts. One signficant contributor is known as 'VDR Deafness' which affects Rockwell Collins VDRs and accounts for approximately 50% of the PAs seen currently. An update to address this problem is now available and known to work, so in order to find other causes of provider aborts it has been decided to investigate PAs that occur in aircraft that are fitted with the update for VDR deafness. These aircraft of special interest are being closely monitored and any PAs investigated.
The following aircraft are known to have the version of the Rockwell Collins 2100 VDR that includes the update for the VDR deafness problem from at least the dates given (and possibly before):
