There is only one other BK117 in service in the UK. This is with the Cornish police force. 

The BK117 is the de-facto helicopter used as an air ambulance internationally. Over 500 BK117s are in service world-wide. 80% of these are used for air ambulance or search and resue operations.

Top speed is 150 knots (172mph)

Cruises at 130 knots (150mph)

Fuel consumption is 4kg per minute (approx 300 litres per hour)

Fuel capacity is 558kg (697 litres).

Two hours endurance (one full tank of fuel)

Burns around 300 litres of fuel per hour

The BK117 can be equipped for night-time flying in cloud - this is referred to as Single pilot IFR

At night-time the helicopter could not, as such, be used as an air ambulance in the same way as it is during the day. This is because the crew would not be able to see where they are landing as cables, ditches, fences and other obstacles could not be seen. Instead, it is capable of taking off and landing at approved sites, lit airports and helipads. In this way, a BK117 could transfer critically ill patients from one hospital to another.

Crew

The crew consists of a pilot and a doctor and highly skilled paramedic.

Equipment

Both helicopters are equipped with a special stretcher, defibrillator/multi-oxygen in the blood, twelve lead ECG and Respiratory ventilator.

Running costs

It costs £2.4m just to keep two helicopters flying. When we add in the cost of employing doctors together with purchase of suits, helmets, helipads, fundraising and admin costs, this figure rises to £4.2m - a frightening sum to have to raise but it equates to less than £1 per person in this region per year.
