  • B

    VFE: Maximum flap extended speed

  • C

    VS1: Stall speed with flaps up

Refer to figure.
Here are the different speeds with the associated visual indicators (colored arcs) of an airspeed indicator:

White arc:

  • Lower limit – VS0: stalling speed with flaps extended. (1)
  • Upper limit – VFE: maximum speed with flaps extended. (3)

Green Arc:

  • Lower limit – VS1: stalling speed in clean configuration. (2)
  • Upper limit – VN0: maximum speed in normal operation. (4)

Yellow arc:

  • Lower limit – VN0: maximum speed in normal operation. (4)
