The Convertible passenger/freight version had a 3.4m x 2.18m (138in x 86in) side cargo door (SCD) on the forward port side for pallet loading. They also had strengthened floors and additional seat tracks. As a freighter it could accommodate seven LD7 (88in x 125in) palettes on the main deck plus any loose cargo in the two holds. Conversion time was approximately 3hrs but this was later reduced to about 1hr with the QC which had 12 passenger seats ready mounted on each pallet. This realistically allowed the aircraft to used for both roles allowing it to earn money around the clock by carrying pax by day and freight overnight. Some airlines even operated them as Combi's with pallets at the front and pax at the rear.
