How An Airplane Flies Flashcards
What are the four aerodynamic forces acting on an airplane in flight.
The four aerodynamic forces acting on an airplane in flight hour left, wait pulling it down, trust pulling the airplane forward through the air and drag which wants to slow the airplane down and oppose his trust. Left opposes weight.
How is lift created
The decreased pressure on the top of the wing combine with the increased pressure at the bottom of the wing creates the lift.
What is the angle of attack
The angle between the relative wind and the wing cord line is the angle of attack and it is abbreviated as AOA
What angle of attack are most general aviation aircraft designed to stall
Most general aviation aircraft are designed to stall at an angle of attack of baby in 15 to 20°.
What are the three axis of rotation
The three axis of rotation are the vertical axis the lateral axis and the longitudinal axis they all intersect at the center of gravity
Which flight controls are used to turn the aircraft on the three different access.
The rudder is used to turn the aircraft on the vertical axis. The yoke is used to turn the aircraft on the lateral axis. The ailerons are used to turn the aircraft on the longitudinal axis.
What are the two types of lifts involved in turn
The two types of lifts involved are the vertical left and the horizontal left compared to just a straight up left in a straight flight.
Three types of banks
Shallow bank is 20° or less. Iran and writer pressures must be held into the turn to keep the Airplane from rolling out of the turn. Medium bangs are 2245° and often 30°. The airplane will maintain a constant bank with little aileron all right a pressure. Steep banks are 45° or more in this situation, opposite aileron and Arada pressures are needed.
What is a load factor
The increased weight that the wings have to support is called load factor. For example when you increase the angle of attack, total left increases because of Waze now I have to support the horizontal component of the plus the vertical component of left. This increased weight the wings have to support is called load factor.
Load factor defined
Load factor is the total weight the wings have to support divided by the gross weight of the airplane. Load factor is expressed in the term G. Load factor can be increased by increasing the angle of bank flying in turbulence or pulling out of a dive. An increase in load factor will increase in airplanes stall speed. However the airplane will always start at the same critical angle of attack. With increased load factor the wing which is the critical angle of attack at a higher speed.
What are the normal and utility category aircraft types
Aircraft certified for normal category unstressed for3.8 positive g and 1.5 negative g.
Aircraft certified for utility category are stressed for4.4 positive gravity and 1.76 negative gravity.
How do you avoid excessive airframe stress
Your void airframe stress by flying your aircraft in turbulence at the maneuvering speed which is abbreviated as V small A
What is the relationship between maneuvering speed and the weight of the aircraft
The maneuvering speed is directly proportional to the weight of the aircraft. If the total weight of the aircraft is lowered then the maneuvering speed will also be lower.
What are the three major causes that creates the left turning tendency of the aircraft.
The three major causes are torque, propeller factor also called P factor or asymmetrical trust and slipstream affect.
What is the P factor.
The P factor also called the asymmetrical trust or propeller factor occurs when one side of the propeller produces more trust than the other which leads to the airplane yaw in the opposite direction.
