How do I correctly interpret the second case in the A320 fuel leak procedure, where it says "Leak from engine/pylon not confirmed or leak not located"?
This part of the procedure calls for the actions to be done to determine if the fuel leak is from the engine, wing, or center tank. If cabin crew and passengers or the Pilots themselves observe a fuel trail from the wing away from the engine and pylon; fuel SD page shows the respective side fuel decreasing, will I be right to say that we can safely assume that the fuel is leaking from the wing tank, without having to run this part of the procedure of shutting down the respective side engine etc? My instructor says we should still run this procedure regardless, but It seems obvious to me it's from the tank in this case. Unnecessary to apply this procedure to conclude the leak is from the wing. Any objections?
