BN2T-4S - Defender 4000 Surveillance Aircraft

A continuous programme of research and development since the design of the first Islander has resulted in many variants in both civil and military roles. Defender 4000 is the latest development of the BN2T Defender aircraft - in service with government and law enforcement agencies world-wide - meeting the need to operate a lightweight aircraft from short airstrips in all weather conditions, by day and night.

Design improvements include an extended fuselage, larger wing for greater internal fuel capacity and enhanced visibility cockpit and cabin. The Defender 4000 is designed to carry the most sophisticated navigation and sensor equipment such as thermal imaging camera and 360 degree search radar (optional extras).

The standard aircraft incorporates advanced avionics, an electronic flight instrument system (EFIS) and a full range of communications equipment. Twin Rolls Royce (Allison) Turbine engines, which are flat rated at 400HP, are also fitted as standard.

A new nose structure has been developed specifically to accommodate a high performance 360^o rotating antenna. The nose section can also be modified to accommodate a 3 axis FLIR ball and 120 degree sector scan surface search and weather radar. For information on other radars including a full 360 degree surface search / MPA radar, please contact the BN Sales department.

The Defender has been tried and tested to meet your operational requirements:

Internal features Airline type crew seats with sliding seat rails allowing flexible positioning of seats and equipment along the fuselage Spacious cabin area with option for limited toilet facilities Space for a minimum of two consoles and operators along one side of cabin Modular set-up to allow expeditious removal of LRUs if required Static line or free-fall parachuting fit Additional equipment such as SAR dinghy, markers	External New nose - able to accommodate 27 inch, 360^o rotating antenna or "FLIR ball" Deep windscreen, improving visibility for observation (240^o visual look-out) 4 hardpoints (2 under each wing) - 750lb inboard and 350lb outboard each Thermal imaging - 360^o cover Rear sliding door with blister window DV panels for increased all round visibilty High wing aids surveillance ops
STOL capability Operates readily from 400m unprepared strips - including beaches, jungle clearings and grass Wide wheel track and double main wheels for optimum ground roll stability Low-pressure tyres (35psi/2.4 bar) for soft-field operation	Ease of maintenance High ground clearance for propeller minimises damage from debris Easy access service panels No special tools required Elevator and rudder trim tabs Dual mainwheels interchangeable with nosewheel
Multi-Role flexibility Uninterrupted square-section fuselage and flat cabin floor for rapid reconfiguration Low load height and two wide side doors for easy passenger and cargo access High-wing configuration providing maximum unobstructed field of view for surveillance tasks Economical low loiter speed with twin-engine safety for policing and land or sea surveillance Four under-wing hard points for external stores Optional special-mission features including sliding door (opens in flight), blister windows and full-length sliding seat rails/cargo tie-down points
Powerplant reliability "Powered by Rolls-Royce" - all our turbine aircraft are equipped with the Rolls-Royce Model 250 engines.	Proven features The Defender 4000 inherits three main features which dominate in the success of all the Britten-Norman turbine aircraft: Exceptional airframe fatigue life - with aircraft still successfully operating after 25 years Anti-corrosion airframe - all BN aircraft are designed to operate at low level and are therefore built with the utmost resistance to corrosion
Economy Less then one maintenance man-hour for every revenue hour flown with low Direct Operating Costs
