The yellow and green helicopter touched down in fields behind Landguard Holiday Park off the public bridleway SS18A shortly before 11:30.
The HEMS team have joined local paramedics at the popular holiday park in response to an individual being taken ill.
HIOWAA were also in Shanklin yesterday afternoon (Saturday) when a man required assistance at a residential address in the Westhill Drive area.
UPDATE @ 12:15 – The air ambulance doctors and paramedics have now left the scene and are returning to their base in Andover.
The crew were transferred back to the helicopter by an off-road vehicle belonging to the holiday park.
The patient has not been conveyed to a mainland hospital – instead they have been taken to St Mary’s Hospital by land.
