When calculating the duration of an excursion above 13 000 ft without oxygen for a HEMS mission, does time spent on the ground at an altitude above 10 000 ft count toward the total excursion time?

Yes, the duration of the excursion includes all time spent above 10 000 ft during the HEMS mission, which includes all time spent on ground above 10 000 ft.

Does the excursion time above 10 000 ft for a HEMS mission include only the time spent in flight, or does it also include time spent on the ground at high altitude?

The excursion time includes both all time spent on ground above 10 000 ft and all time spent in flight above 10 000 ft within a single HEMS mission.

GM1 SPA.HEMS.110(d)(3) Equipment requirements for HEMS operations

Q: In the context of HEMS operations, if a helicopter temporarily descends below 10 000 ft during a mission but does not return to base, does that reset the excursion time above 10 000 ft?

No, temporarily flying below 10 000 ft without returning to base does not reset the duration of the excursion.

SHORT EXCURSIONS ABOVE 13 000 ft WITHOUT OXYGEN

(a) The duration of the excursion includes all time spent above 10 000 ft during the HEMS mission. This includes:

(1) all time spent on ground above 10 000 ft;

(2) all time spent in flight above 10 000 ft within a single HEMS mission.

(b) The HEMS mission ends on return to base. Temporarily flying below 10 000 ft without returning to base does not reset the duration of the excursion.
