India’s leading body of pilots has asked the civil aviation regulator to inspect all Boeing 787 Dreamliners operating in the country for electrical issues after one of the planes abruptly deployed an emergency power system midair over the weekend.
The device, a small propeller that acts as a backup generator and which is known as the ram air turbine, or RAT, normally would be activated when an aircraft's engines lose power, its hydraulic systems register critically low pressure or its electrical systems fail.
