Monthly Dose of Aviation (April 2024)

Hello everyone, this is your monthly dose of aviation.


These secondary flight control devices are found on almost every fixed-wing aircraft and are used very often for different phases of flight. The purpose of flaps is to provide additional lifting surfaces for an aircraft whilst being able to maintain a low-speed flight. You will see flaps being utilized during two main phases of flight: takeoff & landing.

During takeoff, flaps are often extended to help provide lift at lower speeds. This is commonly done to prevent the need for a full-runway takeoff and prevent an overrun due to rejected takeoff. Shortly after takeoff when the aircraft reaches an appropriate speed, the flaps will be fully retracted to make the wing more streamlined again for high-speed climb and cruise. Note, lift will continue to be generated as long as there is a sufficient angle of attack.

During landing, flaps will be extended in intervals as the aircraft continues to slow down and more lift is needed to keep it aloft. However, this can vary very often depending on the approach path, runway size, etc. Flaps will most commonly be extended to their maximum deflection angle to maintain lift and provide as much drag as possible.

That was your monthly dose of aviation…take care!
