Which speed is the most frequently listed among flap settings?

• A. 230 Knots
• B. 240 Knots
• C. 200 Knots
• D. 170 Knots

Answer: (A)

Understanding flap speeds means looking at the maximum speed allowed with the flaps extended (VFE) for each flap setting. On the CRJ-550, the flap-speed charts show 230 knots as the limit for several common flap configurations, so this value shows up most often across the different settings. This arrangement gives a safe operating envelope for most takeoff/initial climb and approach configurations while keeping well within structural limits. The other numbers are used for less common combinations: 170 knots is typically tied to the most extended flap setting, while 200 and 240 knots appear in some specific cases but not as broadly across the chart. That keeps 230 knots as the most frequently listed speed among flap settings.
