Examples

“Based on the reported weather at Carbondale, it should have⟳ been apparent that he would need⟳ electrical power to operate⟳ his radio navigation instruments on arrival since he most probably would have⟳ to execute an instrument approach⟳ to land⟳. Therefore, to insure that he could complete⟳ the 39-minute flight to Carbondale, all unnecessary electrical loads would have⟳ to be shed⟳ in order⟳ to have⟳ residual electrical power. In addition, there was no way the captain could determine⟳ the exact charge state of the batteries when the generators failed; therefore, even with proper load⟳ shedding procedures, the captain could not have⟳ been sure that battery power would last⟳ longer than 30 minutes. Given the two options available to the captain when the generators failed, the risks involved in continuing to Carbondale were such that this option should have⟳ been rejected summarily.”

“Early in the SR 111 investigation, it was discovered that the Swissair MD-11 in-flight entertainment network (IFEN) was connected to aircraft power in such a way that was not compatible with the emergency electrical load-shedding design⟳ philosophy of the MD-11 aircraft. The IFEN was powered from AC Bus 2, a bus that is not deactivated when the CABIN BUS switch⟳ is selected. Use⟳ of the CABIN BUS switch⟳, which was the first item in Swissair’s Smoke⟳/Fumes of Unknown Origin Checklist at the time of the occurrence, is intended to remove⟳ most electrical power from the aircraft cabin.”
