What is Vfe 2?

What is Vfe 2?

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

Answer: (A)

Vfe is the maximum speed permitted with a specific flap setting extended. For flap position 2 on the ERJ 175, the published limit is 215 knots. Going faster than this while the flap is in position 2 risks over-stressing the flap mechanism or causing control issues because the flaps add structural and aerodynamic loads that the airframe is not designed to handle above that speed. So 215 knots is the correct Vfe for flap 2. The other numbers aren’t the official Vfe for this flap setting; they would correspond to other flap configurations or simply not match the aircraft’s published limits.
