The correct answer here is B. Turns. The load is increased when the aircraft is turning, especially at higher speeds with sharper changes in direction.
What increases load factor?
Steep turns at slow airspeed, structural ice accumulation, and vertical gusts in turbulent air can increase the load factor to a critical level.
What is load factor on an airplane?
In aeronautics, the load factor is the ratio of the lift of an aircraft to its weight and represents a global measure of the stress (“load”) to which the structure of the aircraft is subjected: where is the load factor, is the lift.
Why does load factor increase in a turn?
The horizontal component works against centrifugal force in a turn. The vertical component is therefore reduced to be less than your weight. To stay at a constant altitude, you have to increase the angle of attack by pulling back on the yoke (and trim). The pitching action will increase the load factor.
What are the four flight fundamentals involved in maneuvering an aircraft?
There are four fundamental basic flight maneuvers upon which all flying tasks are based:
- straight-and-level flight,
- climbs, and.

Does load factor increase with speed?
But what does load factor have to do with stall speed? Stall speed increases in proportion to the square root of load factor. You can see from the diagram above that as load factor increases, stall speed increases at an exponential rate.
What is load factor formula?
The load factor percentage is derived by dividing the total kilowatt-hours (kWh) consumed in a designated period by the product of the maximum demand in kilowatts (kW) and the number of hours in the period. In the example below, the monthly kWh consumption is 36,000 and the peak demand is 100 kW.
What does G mean in aviation?
Page 1. OK-10-0876. Acceleration in Aviation: G-Force. Acceleration in Aviation: G-Force.
How is aircraft load factor calculated?
The load factor is the ratio of the lift required in a turn to the lift required straight and level flight. So the formula for load factor = 1 / cos phi. The load factor in a turn depends only on angle of bank.
What is the definition of load factor?
: the percentage of available seats paid for and occupied in an aircraft.
How many G’s is a 60 degree turn?
Load factor and accelerated stalls: A constant-altitude turn with 45 degrees of bank imposes 1.4 Gs, and a turn with 60 degrees of bank imposes 2 Gs. Stall speed increases with the square root of the load factor, so an airplane that stalls at 50 knots in unaccelerated, level flight will stall at 70 knots at 2 Gs.
Why is the load factor higher than 1 in a level turn?
N = T/D 1B) Why Is The Load Factor Higher Than 1 In A Level Turn? (28.2) A. Because Only A Portion Of The Lift Is Use To Balance The Weight. … It’s Wrong Because The Lift Is Constant In A Level Turn And The Induced Drag Increases, So L/D …
What is G limit?
What is G limit and why is it important in jet fighters? … With in the envelope, say one where speed and load factor (g’s) are expressed on a plot, you’re ok if you remain within the boundary. Once you cross the boundary, the aircraft may stall, of fail to continue to perform adequately in some other manner.
Can a plane fly without a rudder?
Without the rudder the aircraft can still be controlled using ailerons. The tail-plane helps provide stability and the elevator controls the ‘pitch’ of the aircraft (up and down). Without these the aircraft cannot be controlled.
Do planes lose altitude when turning?
If as you bank into a turn, you increase the engine power by just the right amount you will not lose any altitude. … If this is done without adding power then the plane will slow down a bit due to increased drag, but the extra angle of attack will be enough to maintain altitude.
What are the 6 fundamentals of flight?
Principles of Flying. (1) Lift, (2) Gravity force or Weight, (3) Thrust, and (4) Drag. Lift and Drag are considered aerodynamics forces because they exist due to the movement of the Airplane through the Air.
