Eurocopter EC-155

TYPE: Light utility helicopter.

PROGRAMME: Programme launched September 1996, as further development of Dauphin 2. Announced at 1997 Paris Air Show, when known as AS 365N4 Dauphin 2. First flight 17 June 1997 as conversion of DGV testbed F-WDFK (see AS 365N Dauphin 2); 1,000 flying hours achieved by February 1998. New, EC 155 designation revealed at HAI convention, February 1998. First production EC 155 (F-WWGZ) flew 11 March 1998. JAR certification received 9 December 1998. FAR certification was due late 1999. Certification for single pilot in IFR issued 25 January 2000.

CURRENT VERSIONS:

EC 155B: Baseline version; replaced in 2002; MTOW 4,800kg and Arriel 2C1 engines.

EC 155B1: Upgraded version from 2002; as described. Features include new engine cowlings, new hydraulic cooling system, chip detectors, cargo fire protection, jettisonable cockpit doors; fixed cockpit footsteps and Thales AHV 16 radar altimeter display. Available with standard Corporate, Offshore and Parapublic equipment packages.

EC 155B HTT: Helicoptere Tous Temps (all-weather helicopter). Technology demonstrator (F-WQEZ), first flown 15 October 2002, for evaluation of helicopter navigation, ground collision avoidance and autopilot systems, aimed at relaxation of rules for rotary-wing IFR operations. Equipment includes a GPS/DGPS-based position-finding system which communicates with a ground station at Eurocopter's Marignane facility; four-axis autopilot, permitting steep approaches in zero visibility; and a mission computer with database-stored terrain maps which manages three-dimensional flight plans, coupled with ground collision avoidance system, to ensure safe terrain clearance during en route flight in zero visibility, Mission information is displayed on two large cockpit displays with three-dimensional mapping. Eurocopter expects that the technologies being evaluated in the HTT will be incorporated in its range of helicopters from 2005.

Is this machine still on the market for sale and what is the price.

Marcus, e-mail, 05.02.2010

Please could you provide me with the same information as Christopher and Toray. What is the Burn Rate on the EC 155 B1.

Thank you

Marcus

Christopher, e-mail, 01.10.2008

I have the same questions as torah.

1. altitude of flight envelope for take off and landing?
2. Altitude of flight envelope for re-starting engines?
3. Altitude of flight envelope on cruise?
4. Temperature at flight (max and minimum?
5. Temperature at take off (max and minimum)?
6. Wind limitation for starting the rotor?
7. Wind limitation for take off and landing (on ground and on offshore platforms)?
8. Wind limitation for rear wind?
9. Wind limitation for side wind?
10. Maximum slope gradients for landing/take-off?
11. Maximum slope for starting and stopping the rotor?
12. Maximum slope for landing/take-off with rotor turning?
13. Maximum slope in relation to the plantforms movements (offshore operation)?
14. Maximum pitch/roll/heave limitations (platform landing)?

Let me know if you can help. Thanks

Nimal daud, e-mail, 14.06.2008

I would like to know the height of the rotor blade of the eurocopter AS 365N to ground level when the rotor is spinning at idle,ex: before gear is engaged for takeoff and how low will the rotor droop at this stage to the nose of the heli and what is the proper emplaning and deplaning procedure when the rotor is turning.Must the pilot be at the controls when the rotor is turning.Thank you for your help

fajar, e-mail, 19.03.2008

please send me photo or video ec 155b1 when flotation gear explode. when this happen, can we used the sliding door for evacuate? caused we still confused, afraid if the sliding doors hit the rear flotation gear

torah, e-mail, 22.06.2007

can u give me more details about EC 155B1 expecially aboout fligth envelope.
i have several question about this :

3. Altitude of flight envelope on cruise?
4. Temperature at flight (max and minimum?
5. Temperature at take off (max and minimum)?
6. Wind limitation for starting the rotor?
7. Wind limitation for take off and landing (on ground and on offshore platforms)?
