1.1 What is one purpose of wing flaps?
To enable the pilot to make steeper approaches to a landing without increasing the airspeed.
Extending the flaps increases the wing camber and the angle of attack of the wing.
1.1 One of the main functions of flaps during approach and landing is to
Increase the angle of descent without increasing the airspeed.
1.1 What is the purpose of the rudder on an airplane?
To control Yaw
The rudder is used to control yaw, which is rotation about the airplane’s vertical axis.
1.1 Which is not a primary flight control surface
Flaps
Three primary flight controls of an airplane are the ailerons, the elevator (stabilator), and the rudder.
1.1 The elevator controls movement around which axis
Lateral
The elevator is the primary control device for changing the pitch attitude of an airplane about the lateral axis.
1.1 True Statement concerning primary flight controls: The effectiveness of each control surface increases with speed because there is more airflow over them.
Rudder, alleron, and elevator effectiveness increase with speed because there is more airflow over the surface of the control device.
1.1 True statement concerning flaps: Flaps allow an increase in the angle of descent without increasing airspeed.
Flaps are attached to the trailing edge of the wing and are used during approach and landing to increase wing lift. This allows an increase in the angle of descent without increasing airspeed.
Which device is a secondary flight control?
Spoilers
Ailerons
Stabilators
Spoilers. Spoilers are high-drag devices that assist an aircraft in slowing down and losing altitude without gaining extra speed. They are common on gliders and some high-speed aircraft.
1.1 Trim systems are designed to do what?
They relieve the pilot of the need to maintain constant pressure on the flight controls.
Trim systems are used to relieve the pilot of the need to maintain constant pressure on the flight controls. They include trim tabs, anti-servo tabs, and ground adjustable tabs
1.2 The four-forces acting on an airplane in flight are
? lift, weight thrust, and drag
? lift weight, gravity, and thrust
? lift, gravity, power, and friction
lift, weight, thrust, and drag
1.2 when are the four/forces that act on an airplane in equilibrium
During unaccelerated level flight
1.2 What is the relationship of lift, drag, thrust, and weight when the airplane is in straight-and-level flight?
lift equals weight and thrust equals drag
1.2 Which statements relates to Bermoulli’s principle?
Air traveling faster over_____ of an ____ causes ____
air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface
1.3 The acute angle A is the angle of ___
attack
1.3 The term “angle of attack” is defined as the angle between the…
chord line of the wing and the relative wind.
1.3 The angle between the chord line of an airfoil and the relative wind is known as the angle of
attack
1.3 The angle of attack at which an airplane wing stalls will
remain the same regardless of gross weight.
