Vertical/short takeoff and landing capabilities make helos and turboprops ideal for EMS & 
SAR operations.


By Pro Pilot staff

Leonardo AW139.
Time-sensitive aerial emergency medical services (EMS), and search and rescue (SAR) missions, demand aircraft capable of reaching remote locations and inaccessible sites.

Helicopters and turboprops are ideal for these types of operations, so we’ll highlight the most popular offerings from original equipment manufacturers (OEMs) supplying the EMS and SAR realm.

Rotary-wing solutions

Hovering and vertical takeoff and landing characteristics of helicopters make it easier to locate and extract subjects in SAR jobs. In addition, rotary-wing aircraft are used in the EMS field for faster short-hop patient transportation.

From single-engine options to larger machines, here’s what’s available from the major helo OEMs.


Leonardo

AW119Kx. This single-engine helo is an outstanding performer in hot and high conditions, and it’s broadly used in EMS and rescue missions.

Its cabin can be configured for 4 medical attendants and 1 stretcher, or 2 attendants and dual stretcher. In addition, its modular interior can accommodate advanced life-support equipment.

The helo features wide sliding doors and a 405-lb hoist for SAR operations.

AW139. It features a jointly developed configuration for EMS and SAR missions. In SAR mode, the AW139 is spacious and can be configured to accommodate a fully integrated mission console, medical treatment, and casualty evacuation interiors.

The EMS version accommodates up to 5 medical attendants and 4 stretchers longitudinally and transversely, along with a full suite of advanced life-support equipment. The large sliding doors on each side are designed for easy stretcher loading, both on ground and in flight.

AW169. It ensures a rapid emergency response, even for long-distance inter-hospital transport or for EMS and SAR missions at high altitude.

AW189. Speed, range, and payload characteristics ensure the highest performance in demanding SAR and medical evacuation (medevac) missions, even in icing conditions.

AW109 GrandNew. Designed to operate in challenging conditions associated with EMS and SAR missions over land and water, the GrandNew can accommodate single or dual stretchers with up to 4 seats for medical attendants, or up to 6 seats for medevac.


Airbus H135

Airbus Helicopters

US Coast Guard operates MH-65 Dauphins in SAR guise along the country’s Pacific and Atlantic coasts, in the Gulf of Mexico, and in the Hawaiian Islands. In addition, the Finnish Border Guard has flown AS332 L1 Super Pumas for maritime SAR.

H125 and H130. Both single-engine helicopters are widely used in EMS missions, offering good dispatch reliability and high performance, excellent visibility, mission flexibility, and low operating costs. H125 can transport 1 stretcher and up to 3 medical crew members, plus medical equipment.

H130 has a wide side-loading capability of 7.2 ft, accommodating 1 stretcher and up to 4 medical crew, plus equipment. Furthermore, it can be configured to accommodate up to 2 pilots, 3 crew members and 1 stretcher. H135.

Represents around 25% of the global helicopter EMS fleet, with more than 600 units in service. Its versatile cabin design with side and rear loading capabilities allows the aircraft to be configured in a variety of different EMS interiors, including single-patient, dual-patient, and intensive care transport.

H145. The go-to helo for transport of intensive care patients or incubators, the H145’s high-mounted tail boom and wide-opening clamshell doors facilitate access to the spacious cabin. It’s available with an all-in-one solution, which facilitates triple roles such as hospital transfer flights, transport of emergency personnel, and mountain rescue missions with the support of an external hoist or dual cargo hook system for human external cargo.

H155. Large, sparsely populated areas benefit from its high payload and long range. It offers cabin space that boosts patient care and accommodates bulky medical equipment. This aircraft comes with a glass cockpit and Airbus’s dual digital 4-axis autopilot, which maximizes pilot effectiveness.

H175. Its large cabin size, airborne endurance, range and useful load make this helicopter suitable for intensive care transport and medevac.

Super Puma family (H215 and H225) can be fitted with 6 stretchers for civilian EMS duties and up to 11 stretchers in its military version. It is also proposed in a helicopter intensive care medical service (hicams) configuration.


Bell

Bell 412EP

Bell 525. The manufacturer markets this helicopter in both EMS and SAR configuration. For EMS operations, it offers cabin flexibility and improved situational awareness with its Garmin G5000H avionics suite, improving operational safety in unforgiving conditions.

SAR configuration can be adapted to meet the specific needs of operators. Furthermore, the helicopter’s fly-by-wire system enables greater pilot situational awareness, especially for low speed/low altitude and degraded visual environment conditions.

Bell 505. In EMS configuration, the 505’s flat-floor cabin, 55-inch clamshell door, and easy-to-install interiors make it ideal for fast and efficient patient and medical personnel transport. Rear seat rails can be used to support life-saving medical equipment.

Its G1000H NXi avionics suite provides added situational awareness for flights into high traffic and complex terrain areas.

Bell 407 GXi. An all-composite 4-bladed rotor system provides impressive hover performance and speed, as well as a smooth ride.

It performs well in demanding environments such as high altitudes, arctic conditions, and extreme heat.  A standard bifold door with a 61-inch opening permits quick and easy patient loading and unloading.

Bell 429. Designed with the air ambulance market in mind, the 429’s deck height matches litter height and allows 1-man litter loading with less lifting or back strain through either side or optional aft clamshell doors. Its large cabin allows full body access, optimizing patient care.

Bell 412EPI. Enhancements incorporated in the latest evolution of this platform include Pratt & Whitney PT6T-9 Twin-Pac engines to improve hot and high performance, an optional gross weight kit that increases useful load to 5129 lb, and BLR Aerospace’s Strake and FastFin for better hover performance.
