When flying in a radar pattern downwind, maintain _____ to ____ KIAS in what type of configuration?

• A. 150-200, clean
• B. 120-160, clean
• C. 200-250, clean
• D. 100-140, clean

Answer: (A)

In a radar pattern, you want a stable, energy-rich state on the downwind leg so you can safely turn to the next leg and maintain proper spacing. Flying in clean configuration (flaps up, gear up) minimizes drag, so you can hold a comfortable, controlled speed without fighting excessive nose-down tendency or stall risk in turns. The recommended range of 150 to 200 KIAS gives enough energy to execute standard or gentle turns onto base and final, helps prevent overshoot of the final approach, and keeps you above stall margin during the turns. Too slow a speed on downwind (even in clean config) can bring you close to stall in a turn and make maintaining spacing harder, while too fast can widen your turn radius and make spacing harder to manage. The 150–200 KIAS clean setting strikes a practical balance for most light aircraft in radar patterns.
