Task Book Training for Wildland Operations – Engine (TWO-E) Practice Exam

Type IV air tankers are the smallest class, so their payload is around 200 gallons. That smaller capacity makes them quick to respond and highly maneuverable, which is ideal for initial attack or operations in tight terrain where larger drops could be impractical or risky. In contrast, the other capacities listed correspond to larger tanker classes that carry much more water or retardant, so they don’t fit the Type IV category.
