Double TT baskets have a pilot’s compartment and 8 passenger compartments - inner ones for 4 passengers each, and outer for 2, 3, or 4 each. The overall capacity of the DTT baskets is pilot + 24, 28, or 32 passengers. The pilot’s compartment is suitable for 8 fuel cylinders (excluding the K90DTT; if requested the pilot’s compartment could be extended to accommodate 8 tanks). 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 lowered in accordance with the Flight Manual. The inner height of these baskets is compatible with the King size fuel cylinders.

K85TT or K90DTT Basket?
If you plan to fly 24 passengers, then you have the choice between a K85TT and a K90DTT basket. These baskets differ only in the number of compartments (4 or 8). In general the DTT baskets are more rigid and provide more privacy for passengers. However the DTT basket is heavier.
