What is the Angle of Attack? [1]
When you start flying training, you’ll often hear the angle of attack referenced. But what is the angle of attack, and what is its effect? Having a good understanding of this basic flying concept is crucial
The angle of attack is the angle at which the oncoming airflow meets the wing. It is measured using the wing’s ‘chord line’, a straight line drawn from its leading edge to the trailing edge
The angle of attack influences the aircraft’s behavior on a fundamental level. It is one of the main factors affecting lift, and airplanes need a constant source of lift to fly

It is the topic that confounds more students than any other. There is one and only one defining element of what a stall is
Now, what does that mean? We are going to breakdown stalls, lift, and everything in between.. First, let’s talk about what is meant by “wing.” Yes, those big rectangular things jutting out from a fuselage are wings of course, but when talking about stalls, we are looking specifically at the chord line of the wing
Why bother with a chord line, why not just say “the wing”? Watch what happens to the chord line of the wing as you add flaps, or aileron inputs. The chord line changes as you manipulate control surfaces!

An increase in angle of attack will decrease pressure below the wing, and increase drag.. Which statement is true relative to changing angle of attack?…
Test basic aeroynamics c [4]
|By changing the angle of attack of a wing, the pilot can control the airplane’s lift, airspeed, and drag. An aircraft airfoil is designed to produce lift resulting from a difference in the
vacuum below the airfoil’s surface and greater air pressure above the airfoil’s surface. higher air pressure below the airfoil’s surface and lower air pressure above the airfoil’s surface.
When the angle of attack of a symmetrical airfoil is increased, the center of pressure will have very limited movement. In theory, if the angle of attack and other factors remain constant and the airspeed is doubled, the lift produced at the higher speed will be the same as at the lower speed

2 Which is true regarding the use of flaps during level turns?. Raising flaps will require added forward pressure on the yoke or stick.

Reduce thrust If more lift force is required because of greater operating weight, what must be done to fly at the angle of attack which corresponds to Clmax
It is impossible to fly at the angle of attack that corresponds to Clmax. Which of the following statement is correct: To generate a constant lift force, any adjustment in IAS must be accompanied by a change in angle of attack
The greater the operating weight, the higher the minimum IAS. 1, 2 and 4 4 only 2, 3 and 4 1, 2, 3 and 4 What effect does landing at high altitude airports have on ground speed with comparable conditions relative to temperature, wind and aeroplane weight: Higher than at low altitude

What is true regarding the force of lift in steady, unaccelerated flight?. There is a corresponding indicated airspeed required for every angle of attack to generate sufficient lift to maintain altitude.
If the same angle of attack is maintained in ground effect as when out of ground effect, lift will. A pilot who intends to maintain level flight must coordinate the angle of attack and
If the airplane attitude remains in a new position after the elevator control is pressed forward and released, the airplane displays. If the airplane attitude initially tends to return to its original position after the elevator control is pressed forward and released, the airplane displays
Angle of Attack (AOA) [8]
The Angle of Attack is the angle at which relative wind meets an Aerofoil. It is the angle formed by the Chord of the aerofoil and the direction of the relative wind or the vector representing the relative motion between the aircraft and the atmosphere.
An increase in angle of attack results in an increase in both lift and induced drag, up to a point. Too high an angle of attack (usually around 17 degrees) and the airflow across the upper surface of the aerofoil becomes detached, resulting in a loss of lift, otherwise known as a Stall.
Angle of attack [9]
In fluid dynamics, angle of attack (AOA, α, or ) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving.[1] Angle of attack is the angle between the body’s reference line and the oncoming flow. This article focuses on the most common application, the angle of attack of a wing or airfoil moving through air.
Since a wing can have twist, a chord line of the whole wing may not be definable, so an alternate reference line is simply defined. Often, the chord line of the root of the wing is chosen as the reference line
Some British authors have used the term angle of incidence instead of angle of attack.[5] However, this can lead to confusion with the term riggers’ angle of incidence meaning the angle between the chord of an airfoil and some fixed datum in the airplane.[6]. Relation between angle of attack and lift coefficient[edit]
Ground Instructor Flashcards [10]
Air traveling faster over the curved upper surface of an airfoil causes lower pressure on the top surface.. Bernoulli’s principle states in part that the internal pressure of a fluid (liquid or gas) decreases at points where the speed of the fluid increases.
Lift produced by an airfoil is the net force developed perpendicular to the relative wind.. Experience a decrease in stability and a nose up change in moments.

AUPRTA Rev3 [12]
OEM recommendations – Upset prevention and recovery. Based upon ICAO document 10011, Airbus, ATR, Boeing, Bombardier, Embraer and ICAO have created Revision 03 of the Airplane Upset Recovery Training Aid to emphasize the importance of prevention
Since the original airplane Upset Recovery Training Aid was published, many positive advances with regard to upset training and to Threat and Error Management (TEM) have been made.. The premise of this revision is that an upset exists anytime an airplane is diverging from what the pilots are intending it to do
This was due to the fact that an upset was previously defined as exceeding fixed parameters (unintentional pitch beyond +25 or -10 degrees or bank angles greater than 45 degrees or speed inappropriate for the conditions). Most recovery maneuver training was done only after exceeding these parameters, without paying attention to the reasons of these diversions

Climbing and descending [14]
This lesson builds on the coordination skills learnt in the previous lesson, straight and level. Check with the student what the important elements of the last lesson were
There are a large number of power changes made during this air exercise and it is important the student reviews and practises the coordination of elevator and rudder adjustments with changes in power.. There are generally four types of climb: best angle, best rate, cruise, and recommended (for visibility and engine cooling)
It is recommended you teach the best rate climb and the glide, with a demonstration of the others as time permits.. Now we must learn how to climb and descend to and from straight and level flight, so that we can move towards the circuit lessons.
