1. Capacity 5130lbs Type: – Jet A-1 Avtur.

2. Standby Fuel Load 3000 lbs

Fuel Consumption:1700 lbs/hr

Fuel jettison is not available on this aircraft.


0-139 kts Long Range
0-153 kts Cruise
0-165 kts Max

Radius Of Operation

Approximate radius of action of 250 nm. When fitted with auxiliary fuel tanks this is extended to over 300nm. These figures are based on the aircraft flying at cruise speed, 30 minutes hover on scene, in still air conditions. The standby aircraft are not fitted with auxiliary fuel tanks.


MSL to 15000 ft

Wind Limitations

Rotor start/shutdown 45 kts any direction, for the hover in side/tailwind, limits are 35 kts any direction.

Note: In an emergency situation the captain’s discretion is the deciding factor.

Service Ceiling 15,000 ft

All Weather Capability
The aircraft has all-weather, full IMC, capability to carry out night SAR.

SkyTrac Systems ISAT-100 Flight Following System

Automated flight following and two way data/voice communications between aircraft and ground. The ISAT-100 system transmits short burst data (SBD) and voice telephony via Iridium LEO (Low Earth Orbit) satellites.

Loudhailer System

Sky Shout loudhailer system from aircraft to surface.

Saab Airborne AIS Transponder System

Receives and displays navigation and identity data from vessels and navigation data from aircraft. Also transmits the helicopter’s own navigation data. Parameters received from other aircraft include: position, course and speed over ground, heading, turn rate, navigational status, and position accuracy.

For vessels, MMSI (Maritime Mobile Service Identity) and IMO (International Maritime Organization) number, ship name, call sign, length, beam, type of ship, location of GPS antenna on ship, draft, cargo, destination, and estimated time of arrival are available.

Standalone system receives and transmits data in the VHF marine band and includes R4A Transponder, VHF antenna, GPS antenna, and ruggedized laptop with ICAN Electronic Charting Systems software.

Traffic Advisory System, TCAS 1, Integrated, Honeywell KTA-970

Traffic and Collision Avoidance System

The KTA 970 TCAS I actively interrogates other transponder equipped aircraft for positioning, distance, speed, and altitude of the other aircraft. Features include: active interrogation; tracks up to 60 targets and displays up to 30 targets; displays 8 ranges from 2nm to 40nm; 1,200-knot closure rate; up to 10,000 feet per minute vertical tracking rate.

Homing Equipment

Chelton 935-2 V/UHF Tactical Direction Finder

The Chelton Tactical Direction Finder is a stand alone direction finding system covering the frequency range of 30-410 MHz with five guard receivers to monitor predefined distress frequencies.

Weather Radar (Integrated with AMS for control & display)

Primus 701 Multi-Mode Colour Weather / Search Radar. Basic radar modes and beacon mode.


Collins Avionic Management System using GPS input for navigati

Enhanced Ground Proximity Warning System (EGPWS)

The Honeywell MKXXII EGPWS computer provides terrain alerting. The EGPWS uses aircraft inputs including geographic position, attitude, heading, air-speed, glideslope, landing gear position, and engine parameters. These are used with the internal terrain, obstacle, and airport databases to predict potential conflicts between the aircraft flight path and terrain or an obstacle. A terrain or obstacle conflict results in the EGPWS providing a visual and audio alert.

A graphic display of the surrounding terrain is displayed in the cockpit.


FLIR UltraFORCE II extended performance long-range thermal imagers. The system provides an image through 360 degrees below the aircraft in low light conditions. Position information will be given in latitude and longitude. This system has demonstrated that it can detect a human sea target at a range of 750 m in a wide field of view to both aircrew and rear crew.

First Aid Equipment
A comprehensive list of First Aid equipment is carried on board the aircraft. The rear crew are fully trained in its use, including heart monitoring, defibrillation, advanced airway management, cannulation, fluid management and resuscitation techniques. A Heart monitor and defibrillator is carried aboard all MCA aircraft.

Droppable Equipment

Each aircraft carries RFD 10 man air droppable life rafts and droppable floating smoke cartridges. Also carried are high intensity ACR Electronics droppable strobe lights, with drogue for night marking which have a minimum of 24 hours strobe battery life.

Rescue Equipment
Main Hoist: Max SWL 600lbs. 295 ft cable length. Variable speed 0-325 ft/min.
Standby Hoist Max SWL 600 lbs. 295 ft cable length. Variable speed 0-325 ft/min.

The hoists also benefit from having a safety clutch and a cable severing mechanism
