Bit of a clarification here on your question , the technical log should have MEL/CDL recorded. But different companies have different systems as to where thats recorded. Sometimes its all in one log, sometimes its a separate one with another 'log' for fuel/oil/transit check. From a dispatchers point of view if its something that affects performance then the info should be available for flight planning in advance if possible which means extra fuel etc is already planned to make the job easier for the crew. In the past working with FAA registered jumbo's there seemed to be a variation of procedures between companies so dont know what the legal bit on your side is. If you're preparing the loadsheet you need the info !
