What is the maximum airspeed for flap settings of 30 or 40 degrees?

The maximum airspeed for flap settings of 30 or 40 degrees is 130 knots. This limitation is critical for safety and aircraft performance during operations. Exceeding this speed could lead to structural damage or control difficulties because the aircraft is designed to operate within specific aerodynamic parameters when the flaps are deployed. Flaps are used to increase lift at lower speeds during takeoff and landing, and their effectiveness diminishes if the aircraft is flown too fast with them extended. Understanding these parameters ensures that pilots can operate the aircraft safely within its limits, thus protecting both the crew and the aircraft.
