‘It is like swapping your much loved old Volvo estate for a new sports coupe version. The basics are the same, you just have to change the procedures’

This is how Alf Kitwood, winchman/paramedic with the MCA Coastguard rescue helicopter unit at Lee-on-Solent eloquently describes the conversion process crews are undergoing to change from the old Sikorsky S-61N to the new AugustaWestland AW139 rescue helicopters.

It is anticipated that the changes to the type of aircraft employed will result in an enhanced response for all who have to call on the services of rescue helicopters, particularly for operators of small craft such as lifeboats, tugs and workboats.

Prior to the current changes, similar types of helicopters operated at all four bases but after re-assessing the various requirements and operating conditions, a policy of adopting two different models to suit the individual requirements was decided upon. The Scottish operations often involve responding to requests for long range assistance such as medical evacuations and the selection of the new Sikorsky S-92 was made with that requirement in mind.

The south coast of the UK presents a different set of requirements and geographical conditions. The range requirement is comparatively less and with the area's popularity with the leisure boating sector, and other coastal activities both on land and close to the shore, a quick response is an important requirement. Peter Cardy, Chief Executive of the Maritime and

Coastguard Agency describes this as a ‘smash and grab’ operation in comparison to the two northern bases.

While the AugustaWestland AW 139 has less ‘range’ and survivor capacity than its predecessor, it is significantly faster. This allows for a speedier response, an important consideration when responding to survivors actually in the water or to medical emergencies.

One problem faced by aircrews when winching, particularly from small craft, is the restricted vision for the pilot directly beneath the aircraft. During such operations the winch operator in effect ‘flies’ the helicopter by giving a running commentary of the situation below to the pilot and on some helicopters having a limited ability to actually manoeuvre the aircraft. During a recent visit by Maritime Journal  to view the new aircraft, it was pointed out that the view from the pilot's position was greatly improved in this respect with the new aircraft.

Other noteworthy features include a dual winch and the inclusion of AIS. This latter provision will be of particular use to vessels that are similarly equipped, allowing improved situational awareness for both the aircrews and those perhaps eagerly awaiting their arrival.

The new aircraft are being ferried over directly from Italy, where the crews have been undertaking specialist conversion training which continues at their UK bases. While they will present a different silhouette to their larger predecessors, for many years instantly recognised and much loved by the public. the operational coverage and service provided should be greatly enhanced by these sleek Italian sports coupes.
