The stabilizer is a fixed wing section whose job is to provide stability for the aircraft, to keep it flying straight. The horizontal stabilizer prevents up-and-down, or pitching, motion of the aircraft nose.
What is a stabilizer on a plane?
The stabilizers’ job is to provide stability for the aircraft, to keep it flying straight. The vertical stabilizer keeps the nose of the plane from swinging from side to side, which is called yaw. The horizontal stabilizer prevents an up-and-down motion of the nose, which is called pitch.
What are a wing’s main internal parts?
A few high-wing and most low-wing airplanes have a full cantilever wing designed to carry the loads without external struts. The principal structural parts of the wing are spars, ribs, and stringers. [Figure 3-7] These are reinforced by trusses, I-beams, tubing, or other devices, including the skin.
Which moving parts of the aircraft’s main fixed wings produces lift?
A fixed-wing aircraft is a heavier-than-air flying machine, such as an airplane, which is capable of flight using wings that generate lift caused by the aircraft’s forward airspeed and the shape of the wings.
What two airplane parts vary greatly depending on the mission?
Two major airplane parts that vary greatly, depending on the mission, are the fuselage and the wings.
What are the four forces of flight?
It flies because of four forces. These same four forces help an airplane fly. The four forces are lift, thrust, drag, and weight. As a Frisbee flies through the air, lift holds it up.
What is the shape of an airplane wing called?
An airplane’s wing has a special shape called an airfoil. The airfoil is shaped so that the air traveling over the top of the wing travels farther and faster than the air traveling below the wing. Thus, the faster moving air above the wing exerts less pressure than the slower moving air below the wing.
What are 5 major parts of airframe of a fixed wing aircraft?
The principal structural units of a fixed-wing aircraft are the fuselage, wings, stabilizers, flight control surfaces, and landing gear.
What happens when the four forces are not in balance?
What happens when the four forces are not in balance? The aircraft accelerates in the direction of the largest force.
What are the most important parts of an airplane?

What factor does not affect takeoff?
Crosswind component has no effect on the takeoff distance. If the runway is sloping, a component of the weight acts along the runway and increases or decreases the acceleration force.
How can pilots manipulate flow turning?
Control surfaces such as flaps, spoilers, and slats let pilots manipulate flow turning. How do turbine engines produce thrust?
What is a drawback of leading edge cuffs?
Depending on the cuff length and shape, the leading-edge cuff can exert an aerodynamic penalty for the stall/spin resistance speed obtained, resulting in some loss of cruise airspeed, although sometimes too small “to be detected with production instruments”.
Why is the critical angle of attack especially dangerous when an aircraft is close to the ground?
Why is the critical angle of attack especially dangerous when an aircraft is close to the ground? It is the point at which an aircraft stalls.
What is the purpose of the dihedral angle?
Dihedral is the upward angle of an aircraft’s wings, which increases lateral stability in a bank by causing the lower wing to fly at a higher angle of attack than the higher wing. What it really means is that you can fly more hands off, even in turbulence.
What type of engine turns a propeller?
After World War II, as jet engines gained popularity, aerodynamicists used jet engines to turn the propellers on some aircraft. This propulsion system is called a turboprop. A C-130 transport plane is a turboprop aircraft. Its main thrust comes from the propellers, but the propellers are turned by turbine engines.
