Bravo!, Captain Valerie Wells! You certainly deserve our respects and adulation

To quote clockwork :
9. The MEL does not anticipate the effects of combinations of apparently unrelated unserviceabilities or allow for situations where systems are made inoperative for special purposes such as demonstration, test or crew training. Other provisions may apply to positioning of ferrying flights but these may not necessarily be included in the MEL.
10. The decision to operate the aircraft with multiple unserviceabilities should only be made after due consideration of possible inter-related or additive effects
There always hidden dangers and unforseen risks involved with dispatch with multiple failures, especially the scarebus! I read of a Malaysian guy who took an A330 despatched with an wingtip breaker problem down to ADL only to have the aircraft AOG over there after the f/o messed with the aircraft clock. Even the Airbus technical rep was flummoxed not realizing the undocumented tie between the cockpit clocks and the maintenace computer time base. It pays to tread carefully with the scarebus!
