You have no muscles in your fingers only tendons. The muscles in your lower arm control your hand movements and grip strength
lift decrease and increase drag
lower the gear,set the flaps to land and land smooth
Two joint muscles in the upper limb is the wrist and the elbow. Two joint muscles in the lower limb is the ankle and the knee.
The skin is superficial to the muscles. The muscles are deep to the skin.
A crosswind can suddenly make your airplane plummet down. It is good at these times to have the extra lift resulting from down flaps. The plane travels slower, but has much better pilot control.
yes
Lower abdominal muscles
They reduce engine speed and extend 'flaps' which allows the wing to keep lift at lower speed.
An aircraft flap is simply called a "flap." Flaps are movable surfaces located on the wings of an aircraft. They are designed to change the shape and configuration of the wing during different phases of flight. By extending or retracting the flaps, pilots can adjust the lift and drag characteristics of the aircraft, allowing for changes in speed, angle of descent, and takeoff and landing capabilities. Flaps can be divided into several types, including: Plain Flaps: These are the simplest type of flaps, which extend straight down from the wing when deployed. Split Flaps: These flaps are divided into two sections, with the lower section extending downward and the upper section remaining in place. Slotted Flaps: Slotted flaps have a slot or gap between the wing and the flap, which helps to increase lift at lower speeds. Fowler Flaps: Fowler flaps extend backward and downward, increasing both the wing area and camber, which allows for greater lift generation. The specific type of flap used on an aircraft depends on its design and intended purpose. Flaps play a crucial role in controlling and maneuvering an aircraft, particularly during takeoff and landing.

Your abdomen muscles are included in the lower torso as well as your obliques.
