SPA.VEMS.125 Performance requirements for VEMS operations

VEMS OPERATING SITE DIMENSIONS AND FEATURES

(a)A non-pre-surveyed VEMS operating site, when selected from the air, should have a minimum dimension of at least 2 × D. The operator may establish alternative criteria for non-pre-surveyed VEMS operating sites, when selected from the air, together with operating procedures and training, which mitigate the risks identified in the operator’s risk assessment to a level as low as reasonably practicable. In this case, the operator may choose not to define minimum site dimensions.

(b)A pre-surveyed VEMS operating site should have a minimum dimension of at least 2 × D.

(c)The VEMS operating site features should enable the VCA to adequately clear all obstructions.

LEVEL OF RISK AS LOW AS REASONABLY PRACTICABLE When landing at a VEMS operating site where additional controls and mitigation measures are not economically or reasonably practicable, in particular after LDP, the associated risk is considered as low as reasonably practicable.
