The purpose of mooring is to prevent damage to the aircraft on the ground in high wind conditions.
However, mooring points are not always present in the parking area or they might exist in insufficient numbers or at inappropriate positions to allow a straightforward application of the AMM mooring procedure
For aircraft on ground parked or in storage in areas, where anchor ground rings are not present, the following alternative can be proposed:
–Two concrete blocks with a mass of at least 2.5t each (represented as green rectangles on the sketch below) are positioned forward and aft of the NLG and of each MLG. Wood or rubber mats are fitted underneath the concrete blocks to increase the friction coefficient.
