This type has a pilot’s compartment and 4 passenger compartments, each accommodating 2, 3, 4, 5, or 6 passengers. The pilot’s compartment is designed for the pilot plus 6 fuel cylinders. The overall capacity is then pilot plus 8, 12, 16, 20, or 24 passengers. There is an option to have an extra crew person or passenger in the pilot compartment, however, the number of fuel cylinders would have to be reduced in accordance with the Flight Manual.
The inner height of the K32TT and K50TT can be increased to accommodate 40 kg fuel cylinders. In baskets larger than the K50TT the side dimensions are raised to fit 40 kg fuel cylinders. The K85TT basket’s width can be extended by adding 30 cm (12 inch) to the pilot’s compartment. This extension increases the space for fuel cylinders to 8.
