What is Vfe 4?

Explanation:
Vfe is the maximum airspeed permitted with the flaps in a given extended position. For the ERJ 175, when the flaps are at setting 4, the published limit is 180 knots. Extending more flaps increases wing surface and drag, which reduces the safe speed range and could stress the flap mechanisms if you go faster. So with flaps at 4, you must not exceed 180 knots. The other speeds would either be for different flap settings or exceed the limit for this configuration.
