However, if a system or equipment defect is detected during flight, the MEL information may be useful to assess the likely dispatch condition for the next flight. A detailed description of the defect detected should be entered in the tech log, and Operator’s dispatch or Maintenance Control Center notified so they can consult MEL when the aircraft arrives.If several aircraft system functions or equipment are inoperative, operators should consult the MEL for each individual item to check if there are any incompatibilities for each of the associated dispatch conditions. If there is no MEL restriction, it is the flight crew’s responsibility to assess the situation and to decide whether or not to dispatch the aircraft with multiple inoperative items. this is for training purposes only, always consult your specific manuals and make sure you are doing well.
