AMC1 SPA.HEMS.110(d)(3) Equipment requirements for HEMS operations ED Decision 2023/007/R SHORT EXCURSIONS ABOVE 13 000 ft WITHOUT OXYGEN (a) [SPA.HEMS.110(d)(3)](#_DxCrossRefBm927679422) limits the duration of excursions above 10 000 ft without oxygen to 30 minutes within a HEMS mission, this being the maximum limit. However, the operator should consider further limiting the duration of the excursion depending on the concrete maximum flight altitude. For that purpose, the operator should meet either of the following: (1) The operator should comply with the maximum flight altitude and the maximum duration of the excursion above 10 000 ft without oxygen as defined in Table 1; or (2) If the operator expects flight durations above 10 000 ft greater than 15 minutes but no greater than 30 minutes, combined with a maximum altitude between 14 000 and 16 000 ft, the operator should define its own limitations within these boundaries based on scientific evidence of no risk of hypoxia. ***Table******1 — Maximum duration of the excursion above 10******000******ft, based on the maximum altitude reached*** <table border="1" cellpadding="0" cellspacing="0"><tr><td valign="top" width="291"><p><i>Maximum altitude</i></p></td><td valign="top" width="307"><p><i>Maximum duration of the excursion above 10 000 ft</i></p></td></tr><tr><td valign="top" width="291"><p><i>14 000 ft</i></p></td><td valign="top" width="307"><p><i>30 minutes</i></p></td></tr><tr><td valign="top" width="291"><p><i>16 000 ft</i></p></td><td valign="top" width="307"><p><i>15 minutes</i></p></td></tr></table> AMC1 SPA.HEMS.110(d)(3) Equipment requirements for HEMS operations ED Decision 2023/007/R SHORT EXCURSIONS ABOVE 13 000 ft WITHOUT OXYGEN (a) [SPA.HEMS.110(d)(3)](#_DxCrossRefBm318087042) limits the duration of excursions above 10 000 ft without oxygen to 30 minutes within a HEMS mission, this being the maximum limit.
