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 aircraft load factor?
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. is the weight. Since the load factor is the ratio of two forces, it is dimensionless.
What is load factor in transport?
Load Factor: The load factor is the ratio of the average load to total vehicle freight capacity (vans, lorries, train wagons, ships), expressed in terms of vehicle kilometres. Empty running is excluded from the calculation. Empty running is calculated as the percentage of total vehicle-kilometres which are run empty.
What is the load factor in a level 60 degree bank turn?
A level 60-degree-bank turn, for example, doubles an airplane’s load factor (to 2 Gs) and raises its stall speed to 70 knots from 50 knots at 1 G.
What is average load factor?
Definition: Load factor is defined as the ratio of the average load over a given period to the maximum demand (peak load) occurring in that period. In other words, the load factor is the ratio of energy consumed in a given period of the times of hours to the peak load which has occurred during that particular period.
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 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.
How do you calculate cargo?
In these cases, Volumetric Weight is used to calculate the shipment freight cost. International Volumetric Weights are calculated using the formula below: Length X Width X Height in centimetres / 5000 = Volumetric Weight in kilograms. Multiply the length x height x width in centimetres and divide the answer by 5,000.
How do airlines increase load factor?

How do you calculate break even load factor?
The formula for this calculation is to divide the total operating costs by the total number of miles flown multiplied by the number of seats onboard the aircraft.
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 a rate one turn?
By definition, a rate one or standard rate turn is accomplished at 3°/second resulting in a course reversal in one minute or a 360° turn in two minutes. A rate one half turn is flown at 1.5°/second and a rate two turn at 6°/second.
Why does stall speed increase with altitude?
At higher altitudes, the air density is lower than at sea level. … For example, the indicated airspeed at which an aircraft stalls can be considered constant, but the true airspeed at which it stalls increases with altitude. Air conducts sound at a certain speed, the “speed of sound”.
What is a good load factor?
A high load factor u2014 anything over 70% u2014 is considered good. It means that your peak demand curve is relatively level. It’s an indication that you’re spreading out your demand, resulting in a lower peak demand charge. A lower load factor means that you have a higher peak demand compared to your average load.
What is the effect on load factor?
It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load factor.
How do you calculate average load?
Average Load Formula
- Daily Average load = Units generated in a day / 24 hours.
- Monthly average load = Units generated in a month / Number of hours in a month.
- Yearly average = Units generated in year / Number of hours in a year.
