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) 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.
