Refer to Figure 4. The upper limit of the WHITE arc on the airspeed indicator represents which airspeed?

Choices

  • ✓ Maximum flap-extended speed (VFE)correct

    The white arc is the flap operating range; its upper end is VFE, the maximum speed with flaps extended.

  • Never-exceed speed (VNE)

    VNE is the red radial line at the top of the yellow arc, not the top of the white arc.

  • Maximum structural cruising speed (VNO)

    VNO is the upper end of the green arc (start of the yellow caution range).

  • Power-off stalling speed, clean (VS1)

    VS1 is the lower end of the green arc; the lower end of the white arc is VS0.

Why

The white arc marks the flap operating range. Its lower end is VS0 (stall, landing configuration) and its upper end is VFE, the maximum speed at which flaps may be extended.
