A Super Puma was on final approach towards the airport.
1 minute before the landing phase, a passenger used a mobile phone.
Loss of all flight and navigation parameters occurred on the 4 integrated flight display system (IFDS) screens.
The displays blacked out for a second during the most critical phase of the flight: landing.
A switched-on mobile phone was placed in the luggage compartment onboard a Sikorsky S76.
The mobile caused a false fire alarm during flight.
Why did it happen?
The use of mobiles on board aircrafts may seriously compromise the navigation systems and safety of the flight.
Research concluded that calls could generate interferences able to disturb the flight instruments and lead to:
- false alarms being triggered directly in the cockpit
- malfunction of the navigation systems
- interferences in the pilots’ communication systems (ear-phones).
What did they learn?
Strictly ban the use of mobile phones/electronic devices on exploration and production operated flights.
On commercial flights, you must comply with instructions given by flight crew.
Mobile phones/devices must be switched off as soon as the engines start and must remain switched off until the engines completely stop.
Taxiing phases (on runway, before take-off) are not considered safe periods. Aircraft equipment can still be disturbed by use of phones.
Ask yourself or your crew
What can we do to make sure all personnel are aware of the consequences of use of mobile phones and/or electronic devices onboard flights?
What actions can we take to prevent this happening:
- as individuals?
- as an organisation?
