What is the maximum flap extended speed (Vfe) for Flaps 45?

• A. 160 KIAS
• B. 175 KIAS
• C. 170 KIAS
• D. 180 KIAS

Answer: (C)

The maximum flap extended speed (Vfe) indicates the highest speed at which the flaps can be safely extended and used. For Flaps 45 specifically, the value of 170 KIAS is typically the threshold for maintaining safe aerodynamic performance during operations with those flap settings. Using Flaps 45 provides increased lift and is often used during approach and landing phases of flight. Exceeding Vfe while flaps are extended can lead to structural issues or reduce control effectiveness. Levels for Vfe can depend on aircraft design and its operational limitations, which are often outlined in the Pilot Operating Handbook (POH) or aircraft flight manual. In this case, the correct value of 170 KIAS serves as an important operational guideline that pilots must adhere to in order to ensure safety and adhere to performance limitations while flying with Flaps 45 deployed.
