What other flap settings are available on the 737?

• A. Between 1 and 25 degrees
• B. 0 to 15 degrees
• C. 10 to 20 degrees
• D. Between 5 and 30 degrees

Answer: (A)

Flap settings are fixed positions, measured in degrees, that change lift, drag, and stall behavior. On a 737, takeoff and initial climb use smaller flap angles, such as 1, 5, 10, 15, and 25 degrees, while the larger positions (30 and 40 degrees) are used mainly for landing. The question asks for the range that covers the other flap settings you’d encounter beyond the extreme landing positions. The range from 1 to 25 degrees best fits the typical takeoff/transition flap settings, making it the most appropriate choice among the options. The other ranges either omit standard takeoff settings or include positions used primarily for landing.
