Summary:

On approach to London Heathrow Airport, in IMC and icing conditions, there was a loss of communication between the Probe Heat Computers (PHC) and the Centralised Fault Display System (CFDS). 皇冠体育app associated Electronic Centralized Aircraft Monitoring (ECAM) actions required the crew to select ADR3 as the data source for the commander鈥檚 instruments.
