Condition: The flap position indicators disagree with flap handle
position and no asymmetry is indicated.
If indicated flap position is 30 or greater and less than 40:
Land using existing flaps.
Set VREF 30 for landing.

placard speed for flaps 40.
If indicated flap position is 15 or greater and less than 30:
Land using existing flaps.
Set VREF 15 for landing.
Note: VREF 15 + wind additive must not exceed the flap
placard speed for the next larger flap setting.
