I spent 13 years on the 747 fleet with Singapore Airlines, which included three Combies. It made no difference which aircraft we flew, Pax/Cargo/Combi. The main difference on the latter was a rather protracted fire fighting procedure for the aft cargo compartment which entailed a senior Chief Steward entering the compartment wearing breathing apparatus and equipped with a large extinguisher which had about a six foot extended nozzel. Through out the exercise he had to maintain communication with another crew member stationed at door 4 left, who in turn relayed the info to the flight deck. Fortunately whilst we all had to practise the procedure every 12 months, I never had to put into practice.
