AMC1 SPA.HEMS.125(b)(4) Performance requirements for HEMS operations ED Decision 2023/007/R HEMS OPERATING SITE DIMENSIONS (a) When selecting a HEMS operating site it should have a minimum dimension of at least 2 x D (the largest dimensions of the helicopter when the rotors are turning). For night operations, unsurveyed HEMS operating sites should have dimensions of at least 4 x D in length and 2 x D in width. (b) For night operations, the illumination may be either from the ground or from the helicopter. [applicable until 24 May 2024 — ED Decision 2012/019/R] AMC1 SPA.HEMS.125(c)(4) Performance requirements for HEMS operations ED Decision 2023/007/R CRITERIA FOR THE HEMS OPERATING SITE (a) In order to select a HEMS operating site from the air, the operator should define either: (1) minimum HEMS operating site dimensions of at least 2 × D by day (the largest dimensions of the helicopter when the rotors are turning) and at least 4 × D in length and 2 × D in width by night, to be estimated by the crew from the air; or (2) alternative criteria for the HEMS operating site together with operating procedures and training, which mitigate the risks identified in the operator’s risk assessment. In this case the operator may choose not to define minimum site dimensions. By night, for operations other than HEC, the HEMS operating site should include an area that the crew estimates to be least at least 4 × D in length and 2 × D in width, which should be free of relevant obstacles. (b) The pre-surveyed HEMS operating site dimensions should be at least 2 × D. (c) The operator may provide guidelines to its commanders on whether to land, proceed with e.g. a one-skid landing, hover landing or proceed with HEMS HEC operations. The commander should decide which technique to employ. (d) Before operating at a HEMS operating site, the commander should estimate whether it is suitable for safe operations based on the above and on the environmental conditions. *[applicable from 25 May 2024 — ED Decision 2023/007/R]* AMC1 SPA.HEMS.125(c)(4) Performance requirements for HEMS operations ED Decision 2023/007/R CRITERIA FOR THE HEMS OPERATING SITE (a) In order to select a HEMS operating site from the air, the operator should define either: (1) minimum HEMS operating site dimensions of at least 2 × D by day (the largest dimensions of the helicopter when the rotors are turning) and at least 4 × D in length and 2 × D in width by night, to be estimated by the crew from the air; or (2) alternative criteria for the HEMS operating site together with operating procedures and training, which mitigate the risks identified in the operator’s risk assessment.
