Which value corresponds to Vfe 3?

Which value corresponds to Vfe 3?

• A. 215 knots
• B. 200 knots
• C. 180 knots
• D. 165 knots

Answer: (B)

Vfe is the maximum speed at which you can fly with the flaps in a given extended position. As you raise the flap extension (more flaps) the airplane becomes more draggy and structurally sensitive, so the allowable speed with flaps out must be reduced. For the ERJ 175, flap position 3 is a mid-range extension, so the published Vfe for this setting is about 200 knots. That makes 200 knots the best match among the options. The higher numbers would correspond to less flap extension, which isn’t this setting, while the lower numbers align with more extended configurations.
