HM Coastguard has a new eye in the sky from September
2016, as a Jetstream 41 turboprop aircraft is
being trialled as part of a development to support our search and rescue (SAR)
helicopters.
The new plane is painted in red and white HM Coastguard
colours and will be patrolling the southern and eastern seaboard.
The aim of the trial is to assess whether a fixed-wing
aircraft will provide valuable additional support for our SAR helicopters. The
new capability will help save lives at sea by identifying people, boats or
ships in distress.
The Coastguard Jetstream is provided by Eastern Airways on
behalf of Bristow Helicopters and has a dedicated crew [Editor note – Eastern Airways
is owned by Bristow]. The aircraft will be controlled through the
Aeronautical Rescue Coordination Centre (ARCC), just like our SAR helicopters,
and will be tasked where there is a risk to life and in support of the
helicopters.
If the trial is successful, options for permanent
provision will be explored, possibly in combination with similar requirements
elsewhere in Government.

BAE Jetstream 41
The Jetstream 41 turboprop regional airliner,
manufactured by BAE Systems, is a major development of the Jetstream 31/32
regional airliner family, which entered service in 1982. The Jetstream 31 and
the Jetstream 32EP (enhanced performance) are 19-seat turboprop airliners. The
stretched Jetstream 41 development was announced in 1989, the first flight took
place in 1991 and the aircraft entered service in 1992.
Over 90 Jetstream 41 aircraft are operational
worldwide in both 29/30 seat commuter and 14-seat corporate shuttle
configurations. The Johannesburg-based airline South African Airlink operates
14 J41s serving destinations in South Africa. British Regional Airlines (BRAL)
operate 13 J41 aircraft as a franchisee of British Airways and as Manx
Airlines. United Express’ Atlantic Coast Airlines of the USA have a fleet of 32
J41.
The Government Services of Hong Kong have two
specially modified Jetstream 41 aircraft for operations in the Philippines,
Malaysia, Vietnam and Singapore as well as serving various missions in Hong
Kong.
BAE Systems offer the MACRO (Material and
Component Repair and Overhaul) programme for Jetstream and ATP (Advanced
Turboprop) operators, which provides customers with a fixed maintenance cost
that includes comprehensive spares support for a single fixed rate per aircraft
flight hour.
FLIGHT DECK

The flight deck accommodates the pilot and
co-pilot. The pilots have the Honeywell Primus II digital radio communications
system with dual transponders. The flight deck instrumentation includes a
Honeywell SPZ-4500 fully digital automatic flight control system with a AH-600
attitude and heading reference system (AHRS), an AZ-810 air data computer . The
flight data is displayed on a Honeywell EDZ-805 electronic flight information
system four or five-tube display.
ENGINES

The two Honeywell (formerly Allied Signal) TPE331-14GR/HR
turboprop engines, with a takeoff rating per engine of 1,650shp, drive the
McCauley five-bladed constant speed feathering metal propellers. The engine
intakes have an air-bleed anti-icing system and a two-bottle fire extinguishing
system is installed in the engine nacelles. The propellers are fitted with an
electrical de-icing system. The typical fuel burn, 420kg fuel /hour is between
20 and 40% lower than that of previous generation engines giving the aircraft a
fully passenger loaded range of 1,430km. The J41 aircraft is fitted with a
Smiths engine management system.
LANDING
GEAR
The
aircraft is fitted with tricycle type forward retracting landing gear with twin
Dunlop wheels and tyres. The wheels are equipped with anti-skid three rotor
steel brakes.
