WBM Flashcards
Tread way photo
Xxx
TDP grid size
50 cm in main floor fwd to aft
Latteraly they vary
What can you use to guide you clearing a load
Flowcharts
Floating pallets
When cargo is restrained using d rings only there is no requirement to use the X locks
GRS and flat floor overlap
One free frame reference is to be left before TDR (TL / TL 2 and 3 see load plan) can be used
Shaded part of envelope
Case B ZFW CofG forbidden if the fwd 23% MAC applies see WBM
RPA
Reduced Payload Areas used when enhanced loading reported.
Used for tracked vehicles frame spacing
Load clearances
150mm to allow smoke detection and rapid decompression to work properly
Can go down to 50mm
Max TO, LDG and ZFW reduced tyre px
120 (120)
120 (120)
117.1 (109.6)
78 (78)
Max lateral imbalance
10,000 kg.m
Generally speaking what weight vehicle can come on no problems at all
=< 5,000
As long as footprints are ok (stick to tredway)
Footprint limits consider
Min contact area
Min edge
Quick H-Arm for stability on wheels
Vehicle 7 m (29.1 - 22.0083)
Pallets 12 m (34.2-22.0083)
How many degrees of lateral restraint is required before you need a LAA
Up to 60’, anything over LAA required
4535 chain around what minimum dimension
19mm but down to 11mm with load reduced to 9000lbs
11340 chain around what minimum dimension
22mm but down to 11mm with load reduced to 22000lbs
How does attaching a chain around a floor d-ring effect is restrained value
Down rates the capacity of both 4535 and 11340 chains to those listed in the WBM
LAA with a 11340 also gets reduced
How many TDP?
CH 238
Ramp 56
Quick-release fitting single and double loads
Single 1040 kgs
Double 2080 kgs
Case A and Case B
A- running load less than 1000 kg/m
ULDs equal to or less than 96 in
B- running loads over 1000 kg/m
ULDs over 96 in
Where can you do mixed loading on the ramp with pallets
P1 and P7 only
Use of TDR near pallet
Not one forward or aft
Alongside only for lost if under 137kgs as long as the pallet isn’t over 4535
