New Delhi: After overheating, the Boeing-787 Dreamliner aircraft of Air India and other airlines is now facing cold-related issues in Delhi.
Japan Airlines (JAL) will, from Monday, stop using the Dreamliner on the Delhi-Tokyo route and replace it with the Boeing-777 after being warned of ice crystals forming on the aircraft's General Electric (GE) engines.
A senior JAL official said: "The engine manufacturer (GE) has said that engines being used on the Dreamliner and Boeing 747-8 series flying over 30,000 feet may see ice crystal icing (ICI) formation when the aircraft gets in contact with cumulonimbus clouds. Aircraft have been asked to divert from the flight path to be at least 80 to 90 km away from such clouds. On the Delhi-Narita (Tokyo airport) route, we do not have the permission to divert so much. "
Moreover, the aviation regulator has said that Air India is now unlikely to get permission to use the plane in dense fog using instrument landing system category-III. AI's B-787s may at best be certified for use in Cat-II or shallow fog this winter.
