This aircraft is staffed by two pilots and a specialist Helicopter Transfer Practitioner, or HTP (nurse, paramedic or ODP with additional training in critical care and transfer medicine). The service also works with local neonatal and paediatric specialist retrieval teams who join the crew when appropriate. This EC135 aircraft, G-WASC, callsign Helimed 67, has specialist equipment and can be fitted with purpose designed equipment for transfer of young children and neonates, including a transport incubator. All helicopters are owned by Babcock Mission Critical Services Onshore, who also provide the pilots, base engineers and maintenance for the aircraft. The three H145 aircraft are equipped for night-vision goggle (NVG) operations and have additional lighting fitted for operation in darkness. At present the aircraft operate (weather dependent) from 08:00 to 20:00, seven days a week. In addition to the four aircraft, the charity runs five rapid response road vehicles (RRV), spread across its four bases. These are adapted Audi Q7 with full audio and visual warning systems that carry the same standard equipment as the aircraft, and are utilised if the aircraft is offline, for example due to weather conditions, or as an additional responding resource.
