STRUCTURAL LOADING LIMITATIONS
An aeroplane consists of a flexible structure. The fuselage twists and turns during the flight as an effect of the movement in the air and the aeroplane’s load. To prevent exceeding the maximum allowable fuselage contortion limits have been set.
?
(a) RUNNING LINEAR LOAD LIMITATION
Running linear load limitation is the maximum load acceptable on a compartment floor's fuselage length. This limitation is expressed in kg/cm or kg/inch of the fuselage length. For example: a pallet weighing 2000 kgs with dimensions 88’ X 125’.
The linear load = 2000 kgs/88’ = 22.73 kg/inch
?
(b) COMPARTMENT LOAD LIMITATION
Compartment load limitation is the maximum load acceptable in an entire compartment. This limitation is expressed in kg.
?
(c) UNSYMMETRICAL LOAD LIMITATION
Unsymmetrical load limitation is the maximum load acceptable on one side of a compartment floor.
?
(d) AREA LOAD LIMITATION
Area load limitation is the maximum load acceptable on a given m2 or ft2 of an aeroplane floor. For example: a pallet weighing 2000 kgs with dimensions 88’ X 125’. Convert inches to feet
The Area load = 2000 kgs / (7.33 x 10.42) ft = 26.19 kg/ Sq ft
(e) COMBINED LOAD LIMITATION
The total combined loading for the main deck and cargo holds must not exceed combined linear loading limits.
?
(f) CUMULATIVE LOAD LIMITATION
The cumulative load limitation defines the maximum mass that can be carried forward or aft of a given location.
?
(g) BARRIER NET LOAD LIMITATION
The barrier net load limitation defines the maximum mass that a barrier net can withstand under emergency forward load factors.
