"A rule of thumb to determine the approximate angle of bank required for a standard rate turn is to use 15 percent of the true airspeed. A simple way to determine this amount is to divide the airspeed by 10 and add one-half the result.
The pilot should realize the tremendous additional load that is imposed on an airplane as the bank is increased beyond 45 degrees. During a coordinated turn with a 70 degree bank, a load factor of approximately 3 G's is placed on the airplane's structure.
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.

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%.
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.” Let's suppose our airplane is cruising in straight and level flight at a constant airspeed.
In aeronautics, limit load (LL) is the maximum load factor authorized during flight, Mathematically, limit load is LL = LLF x W, where LL = limit load, LLF = limit load factor, and W = weight of the aircraft. Limit load is constant for all weights above design gross weight.
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.
The load factor is equal to 1 when the aircraft is static on the ground, with only gravity acting upon it. The load factor can therefore be defined as a multiple of gravitational acceleration g.

Definition. The horizontal distance that an aircraft uses to turn is referred to as the radius of turn. It varies as a function of bank angle and the square of the airspeed.
Well, stall speed is usually defined by wing lift curve, and not so much affected by the landing gear. Usually the limitation is on the upper side due to separation. Climb speed is basically engine thrust minus drag, the drag increases the climb speed is lower.
A stall occurs when the angle of attack of an aerofoil exceeds the value which creates maximum lift as a consequence of airflow across it. This angle varies very little in response to the cross section of the (clean) aerofoil and is typically around 15°.
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.
The critical angle of attack is the angle of attack which produces the maximum lift coefficient. This is also called the "stall angle of attack". A fixed-wing aircraft by definition is stalled at or above the critical angle of attack rather than at or below a particular airspeed.
Power off stall (Approach stall)Used to simulate a stall while in a low speed "dirty" configuration(flaps out, gear down, etc.) such as while on downwind, base or final while prepping to land.
The angle of attack (AOA) is the angle at which the chord of an aircraft's wing meets the relative wind. The chord is a straight line from the leading edge to the trailing edge. The critical AOA is an aerodynamic constant for a given airfoil in a given configuration.
Stall speed increases as weight increases, since wings need to fly at a higher angle of attack to generate enough lift for a given airspeed. And wing contamination such as frost or ice can reduce the amount of lift produced by the wing, also raising the stall speed.
The only dangerous aspect of a stall is a lack of altitude for recovery. Stalls occur not only at slow airspeed, but at any speed when the wings exceed their critical angle of attack. Attempting to increase the angle of attack at 1g by moving the control column back normally causes the aircraft to climb.
The load factor is a dimensionless number equal to the average load divided by the peak load. For example, if the average load is 66 kWh/d (or 2.75 kW) and the peak load is 10.5 kW, the load factor is 2.75 kW/10.5 kW = 0.26.
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.
A sister concept is that of seat factor – the portion of seats occupied in a flight. At a sector level seat factor and load factor would be the same as the distance flown at sector level is constant, but at a network level load factor is the weighted average of the sector wise seat factor.
An analysis from Forbes in March showed that the big US airlines, United, Delta, American, and Southwest, need a load factor between 72.5% (Southwest) and 78.9% (American) in order to not make a loss on their flights.
