Load factor (aeronautics) Load factor (aeronautics) In aeronautics, the load factor is defined as 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: Since the load factor is the ratio of two forces, it is dimensionless.

Factor analysis Factor loadings: The factor loadings, also called component loadings in PCA (not sure in Factor Analysis), are the correlation coefficients between the cases (rows) and factors (columns). Analogous to Pearson's r, the squared factor loading is the percent of variance in that indicator variable explained by the factor.

Back to flight page Thrust is the forward movement of the airplane, provided by the propellers or jet engines. Drag is the opposing force of the displaced air, the same force you feel walking into a strong wind. Gravity acts on the airplane, giving it weight. Lift counteracts the weight of the plane, keeping the airplane up in the air. The lift force is equal to the weight when an airplane is in level flight. Bernoulli's principle helps to explain lift. Bernoulli demonstrated that the faster a fluid moves, the less pressure it exerts.

What Exactly Is Tire Load Index? In other words, it’s the amount of weight your tire can support safely. For example, if a tire has a load index of 92, it can support 1,389 pounds at maximum air pressure. Multiply that by four tires (4 x 1,389 = 5,556 pounds) to get your car’s maximum load–carrying capacity.

forces of flight The four forces of flight. The forces of flight are the four forces of lift, drag, thrust, and weight, which act on an aircraft in flight. An aircraft is in a state of equilibrium when the thrust and drag are equal and opposite. It will continue to move forward at the same uniform speed.

- Load factor limitations of an aircraft are shown by a graphics called maneuvering envelope or V−n diagram as it shows the load factor versus airspeed in terms of EAS. An example maneuvering envelope is given in Figure 3. An aircraft cannot fly out of the load factor boundaries given by the maneuvering envelope.

Load factor (electrical) Electrical Load Factor. Electrical Load factor is a measure of the utilization rate, or efficiency of electrical energy usage. It is the ratio of total energy (KWh) used in the billing period divided by the possible total energy used within the period, if used at the peak demand (KW) during the entire period. Thus,

- You should always set your air pressure to your vehicle manufacturer’s specifications as stated in your owner’s manual or on the tire information placard inside the vehicle. The maximum load number, (1653 LBS) is the load carrying capacity of the tire when it is inflated to the maximum inflation pressure. Similar to inflation pressure, this is not the recommended load carrying capacity for the vehicle it is installed on.

Load Factor The number of Revenue Passenger Miles (RPMs) expressed as a percentage of ASMs, either on a particular flight or for the entire system. Load factor represents the proportion of airline output that is actually consumed. To calculate this figure, divide RPMs by ASMs.

Tire code The load index on a passenger-car tire is a numerical code stipulating the maximum load (mass, or weight) each tire can carry. For Load Range B tires, ETRTO (ISO-Metric) standards specify the load index rating at an inflation pressure of 36 psi (250 kPa) (table below), while P-Metric standards measure the load capacity at an inflation pressure of 35 psi (240 kPa).

Lift (force) Lift is the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is the component of the surface force parallel to the flow direction. If the fluid is air, the force is called an aerodynamic force.

What do the load rating letters on tires mean? Load index. The load index refers to the load-carrying capacity of a tire, or how much weight a tire can support. For example, if a tire has a load index of 89, it can support 1,279 pounds (from below chart) at maximum air pressure. Multiply that by four (4 x 1,279 = 5,116 pounds) to get your maximum load-carrying capacity.

Structural load For example, in designing a staircase, a dead load factor may be 1.2 times the weight of the structure, and a live load factor may be 1.6 times the maximum expected live load. These two factored loads are combined (added) to determine the required strength of the staircase.

Factor of safety Factor of safety. Factors of safety (FoS), also known as (and used interchangeably with) safety factor (SF), is a term describing the load carrying capacity of a system beyond the expected or actual loads. Essentially, the factor of safety is how much stronger the system is than it usually needs to be for an intended load.

- Important: When reading the strength (load bearing, weight carrying ability) given in the tables at the bottom of this page you must keep in mind these values are ultimate loads. This means they are the weight/force/load that will cause the fastener to fail/break. They are not the amount of load you can use safely. You must apply at a safety factor of at least 4 for your application/use. That is, if the table says a fastener can support 100 pounds it means you must divide this by 4, and thus not apply more than 25 pounds of force to the fastener.

- this in mind, we can define the 2-D lift, drag, and pitch moment in the following manner: where c (1) is the chord times the unit width that we use for area in the case of 2-D bodies. a non-dimensional form; here we use the chord length. various shaped airfoils in order to generate a data base for aircraft design.

- At max gross weight, with flaps up and pulling on the elevator control only, the positive design limit is typically +6.0 g. V A in this case is 2.4 times the corresponding V S (CAS). But given simultaneous inputs along multiple axes, the design limit shrinks to +4.0 g. V A likewise decreases to 2 x V S (CAS).

- Figuring out how much an individual airplane can carry is a simple math problem: Take the gross weight, subtract the empty weight, and you have a good starting number, called useful load. For example, if our gross weight is 1,600 lbs and our empty weight is 1,100 lbs, we have a neat 500 lbs of useful load.
