What is the Airport Traffic Pattern Base Speed with flaps 25?

In the airport traffic pattern, the speed on the base leg is tied to the flap setting to balance maneuverability, energy, and stall margin. With flaps set to 25, you gain more lift at lower speeds but also more drag, so you fly a comfortable, mid-range speed that lets you maintain a stable turn and proper descent toward the final approach. About 80 KIAS gives enough energy to complete the base turn smoothly, stay clear of stalls, and still line up well for the final without needing to overslow or overspeed in the turn. The final approach, with flaps 25, will be slower, so the base leg speed is kept higher to carry energy into the final. That’s why 80 KIAS is the best choice here.
