Cathay Pacific Flight 780 departed from stand 8 at Juanda International Airport in Indonesia. It took off from runway 28 at 08:24 local time (01:24 UTC). During the climb, both engines experienced small engine pressure ratio fluctuations, with No. 2 engine fluctuating over a greater range than No. 1.[3] Just over half an hour after takeoff, cruising at flight level 390 (about 39,000 ft (12,000 m) above sea level), the electronic centralized aircraft monitoring (ECAM) system displayed an "ENG 2 CTL SYS FAULT" error message.[3] The crew contacted maintenance control to discuss the fluctuations. As other engine operating parameters on both engines were normal, continuing the flight was determined to be safe.[3]
Almost two hours after departure, at 03:16 UTC, the "ENG 2 CTL SYS FAULT" ECAM message reappeared. The crew contacted maintenance control to review the issue. As all other engine parameters remained normal, continuing on to Hong Kong was again deemed safe.
