Why does load factor change?
Airplanes stressed up to but not beyond their limit-load factor should experience no structural damage. This occurs when the airplane turns or the angle of attack suddenly increases (as it does in turbulence). This increase in apparent weight is called an increase in “G-force” or “load factor.”
How does load factor increase?
In level flight in undisturbed air, the wings are supporting not only the weight of the aircraft, but centrifugal force as well. As the bank steepens, the horizontal lift component increases, centrifugal force increases, and the load factor increases.
Does load factor increase with weight?
What is Load Factor? Load factor can be thought of as how much the aircraft’s weight increases. No, it’s not possible to gain weight in mid-air. But forces other than just gravity are acting on an aircraft in flight, and those forces increase sometimes.
What is the load factor in a 45 degree turn?
+1.41G
At 45 degrees, the load factor is +1.41G, and at 60 degrees angle of bank the load factor is doubled to +2G, and the student will feel twice as heavy.
How does banking in a turn create the feeling of increased G load?
The steeper the turn, the greater the seat-pulling force. This force is sometimes called the G-force (or load factor). The example shows that in a 60-degree bank, you and the airplane will feel a G-force of 2 (two Gs). In other words, you and the airplane feel like you weigh twice as much as you normally do.
What happens when the load factor is greater than 1?
A load factor greater than 1 will cause the stall speed to increase by a factor equal to the square root of the load factor. For example, if the load factor is 2, the stall speed will increase by about 40%. Positive and negative load factors Variation of the load factor n with the bank angle θ, during a coordinated turn.
How does a load factor affect the stall speed?
A load factor greater than 1 will cause the stall speedto increase by a factor equal to the square root of the load factor. For example, if the load factor is 2, the stall speed will increase by about 40%. Positive and negative load factors[edit]
How does the load factor affect the speed of an airplane?
In a constant altitude, coordinated turn in any airplane, the load factor is the result of two forces: centrifugal force and gravity. [Figure 3-35] For any given bank angle, the rate of turn varies with the airspeed; the higher the speed, the slower the rate of turn.
What are the load factors in a steep turn?
LOAD FACTORS IN STEEP TURNS. In a constant altitude, coordinated turn in any airplane, the load factor is the result of two forces: centrifugal force and gravity.
