Which speed is highest among the listed flap speeds?

Which speed is highest among the listed flap speeds?

• A. 170 Knots
• B. 185 Knots
• C. 230 Knots
• D. 200 Knots

Answer: (C)

Flap speeds are the maximum airspeeds you can safely fly at for each flap setting. The more the flaps are extended, the lower that maximum speed must be. Conversely, with the flaps retracted or at the least extension, you can fly faster. Among the numbers listed, 230 knots is the largest, so it corresponds to the flap configuration with the least or no flap extension and therefore the highest allowable speed. The smaller values (170, 185, 200) are associated with greater flap extension, which must be kept at lower speeds for safe operation.
