Floor Load Limit Aircraft

The aircraft floor is a precision engineered structure any excess of concentrated mass in one location can cause damage to this structure both endangering the safety of the aircraft and leading to expensive and extensive repairs to the aircraft.

Floor load limit aircraft.

The cargo compartment floor is designed for an evenly distributed load of 732 kg m2 of bulk loads with a maximum load density of 240 kg m3. For example an observer on board an aircraft performing a turn with a load factor of 2 i e. For 1 sq meter area in contact with the floor the limit is 731 for 0 8 sq meter the limit is 731 x 0 81 585 kgs. Floor running load or linear load.

The floor loading for a 100 pound container is determined as follows. Furthermore certain types of uld most specifically 16 and 20 foot pallets have specific maximum. 14 cfr 1 1 16g abbreviation acronym aerodynamics aircraft airline airlines airport airports airworthiness amt atc aviation safety aviation weather avionics bird strike engineering etops faa faa pilot s handbook flying human. A uniform load rating on a beam can easily be translated into what an equivalent maximum point load can be.

It does not mean that a 300 lb. In general whenever the term load factor is used it is formally correct to express it using numbers only as in a maximum load factor of 4. The span table for a 30 psf live load 10psf dead load floor indicates a required fb value of 1 315 and a minimum e value of 1 800 000. The standard used by lufthansa is 2000 kg per square meter.

Next consult a span table to cross reference the spacing and span to find the required fb value for that table s load limits. Either of boxes 3 and 4 with their longest length parallel to the aircraft longitudinal axis correct. Floor loading is the weight of a load ill pounds divided by the area of floor space which the load occupies. A320 214 structural weight limit kg 3402 4536 1497 9435 max floor limit 488 kg m2 732 kg m2 amount of akh volume 3 6m3 3 2 2 max gross weight of akh on all positions 1134 kg table 2 cargo capacities.

If a mass of 50 kg is spread over 1 square metre the distribution load is 50 1 50 kg sq meter. Above limit load intensity 2 500 1 45 344 8 above limit for box 2. For example a floor joist at 16 spacing s that can carry 53 pounds per linear foot would translate into a 318 pound single point load at its. The maximum weight the floor can sustain per square inch foot as provided by the manufacturer.

In the example the joists have a spacing of 16 inches and a span of 11 feet 2 inches. Box 2 was already ruled out. Lineman standing on one leg will fall through the floor. A 2 g turn will see objects falling to the floor at twice the normal acceleration of gravity.

An amount of weight higher than this amount is assumed to damage the uld and hence endanger the safety of the aircraft. It is calculated by dividing the load by the area it covers. Calculating distribution load intensity.
