aircraft.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For most jets, the solution was a <\/span><b>quick software rollback<\/b><span style=\"font-weight: 400;\">\u2014reverting to an earlier version of the ELAC (Elevator Aileron Computer) software.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Experts note this update takes around two hours.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">However, a smaller group of older A320 variants may require complete ELAC hardware replacement, which takes longer and depends on unit availability.<\/span><\/li>\n<\/ul>\n<h3><b>Progress in India: Majority Fixed by Saturday Evening<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">According to the DGCA, nearly 80% of affected Indian aircraft had already undergone the

rescheduling, not widespread cancellations.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Officials reiterated that passengers need not panic, as operational impact remained modest.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A320-family jets operate multiple rotations per day, meaning even brief ground time for updates can cause cascading delays.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Still, airlines managed to avoid
