| Confidence Rating: |  Accident investigation report completed and information captured |
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). The associated Electronic Centralized Aircraft Monitoring (ECAM) actions required the crew to select ADR3 as the data source for the commander’s instruments.
Later, on final approach to Runway 27L, the aircraft suffered a loss of displayed airspeed information on both the commander’s and the standby flight instruments. The crew carried out a go-around using the ‘Unreliable Speed Indication’ procedure from the Quick Reference Handbook (QRH).
The investigation concluded that the loss of displayed airspeed information resulted from a combination of:
- a loss of communication between the Probe Heat Computers (PHC) and the Centralised Fault Display System (CFDS),
- icing of the standby pitot probe resulting in the loss of indicated airspeed displayed on the commander’s and standby instruments.
