Flap Extension Policy

Question 1

What is the AOM policy guidance associated with flap extensions?

Answer 1

• Avoid selecting flaps at or near the Flaps Placard Limit Speed.
• Extend and retract flaps using the PFD flap maneuvering speeds (on the recommended speed schedules).

CAUTION: Extending the flaps at or near the flap placard limit speed can result in an inadvertent flap overspeed in gusty wind conditions. Flap extension significantly above the maneuver speed for the current flap position can result in a flap overspeed if the flap lever is inadvertently moved beyond the requested position.
