Flap extension speed for Flap 30 is

Explanation:
VFE, the maximum speed with flaps extended, is the key idea. Each flap position has a published speed limit to protect the flap system from structural loads and flutter. For a 30-degree flap setting, the published limit is 185 knots. That means you should not maintain flaps at 30 degrees or extend to that position when your airspeed is above 185 knots. Keeping below this speed ensures the flaps operate within their design limits and helps prevent overstress or unwanted control effects. As you slow for approach, you would typically deploy flaps progressively, staying beneath the corresponding VFE values for each setting. If you need to retract flaps, you do so according to the retraction speeds, which are higher than the flap-extended limits but still governed by the aircraft’s published speeds.
