Looking good! Any pics of main 'sliding' door?

Very Smart!

Couple of points:

Emergency exits - it seems as if the pop out windows and the main "over sponson" exit are obstructed by the seats. Nice big windows but only the top two thirds are available judging from the photos - plenty to get caught up on the way out. And how accessable are the handles/tabs?

Litter rack: - It will be interesting to see how these will be used if at all. They would be fine if there were four people to lift the stretcher up there, but only two crew? I suspect the stretcher will stay on the floor.

Floor rails - are those floor rails inside the machine? if so are they going to get in the way?

I don't personally have any photos of the sliding door but will ask the others who were there with me.

Regards

According to MCA the aircraft won't be operational until four months after the Bristow contract at Stornoway ends ,the second aircraft won't be operational until Spring 2008 and there will have to be S61Ns leased meantime to plug gap.Also the southern contracts don't end until mid 2008 so the AW139s won't come aboard until then.So are all the Bristow contracts being extended or are CHC providing temporary cover until then ?

A good looking machine indeed and actually looks as if it can do the job! S61 drivers should feel at home looking at some of the switches on the overhead panel!
A couple of questions though.
Has the auto-hover been certificated yet?
How much ground clearance under the nightsun?
heli1.
By the second aircraft, do you mean the standby/2nd. machine for Stornoway or the first machine at Sumburgh?
Is there any info. on how the 139 is developing or are the rumours of long delays true?

Not bad pitcures, what about the fuel !

Very good looking has to be admitted. Does anyone know how CHC Scotia have aranged the fuel, I mean what is the max fuel on standard tanks ? What is max fuel on auxillary tanks ? and what is the max range ? and what is the average fuel burn in 2000" ?

Over and out

The SAR crewman, (B*****w), standing by the aircraft said that the rear ramp was possibly the most important feature. It allowed the crew better visibility.
The three days prior to Heli-Expo, Goodrich had/has a Hoist Seminar. This one was well attended by the US Army, US Coast Guard, LA County, San Bernadino County, San Diego, Cougar, Bristow and many others.
The next to last presentation was by Chris Bond, Senior SAR Crewman (Tech) for B*****w. He showed a series of videos of rescues done in the North Sea. Very impressive. One was a night rescue off a 30 ft sailboat in 60 ft seas.
SASless take note.

3D CAM....In answer to your question I was referring to the aircraft at Sumburgh not going operational until the Spring.
No news on the AW139 but if not required until mid 2008 ,current winching trials and other coast guard-type tests should be well finished by then.

It looks nice but where is the radar?

Anyone got any comments on the vibration issues which may affect max speeds and RoA?

The radar is in the nose

North Sea Tiger - are you sure? I can see no evidence of a radome or any structure protruding from the nose to give a radar a wide field of view.
Is it just that it has been built in from the start and doesn't require bolt-on bits like the S61?

Crab, it's in the nose, has the same field of view as the current radar on the S61 and the main thing is that it points forwards. So you have a radar which shows what's in front of you rather than whats behind you. Which in my opinion is always an advantage!

Like the S76, the S92 nose fairing is both aerodynamic and a radome.

Not rocket science, crab!

What are the hover characteristics like Nick? Is it as stable as the 61 which is really one of the defining features of the S61? If it has speed and a good, stable hover then the big S have it licked. I hope the 225 is more stable than the L2.

You have to remember I am used to steam driven military aircraft where everything has to be bolted on the outside because capability is always an afterthought - that's why I asked the question.

I presume it is a weather radar - is it cleared for IMC operations below safety alt over the water?

Night Watchman - the problem with having a radar that only looks forward is that you can only do night/IMC letdowns to cliffs/boats etc that are ahead of you. Try doing a letdown into a bay with a 40kt onshore wind and you will find that having an (almost) 360 degree radar is an awful lot more useful. Equally the ability to see all around you in a congested environment (lots of vessels, buoys, rigs etc) at night or in IMC at low level gives you much more SA and flexibility.

I hate to agree with Crab but he's right. With a nose mounted radar as soon as you turn away from the contact to fly a let down pattern you have lost the contact. You then have to hope that you regain the target when it is back in the sector. If the pitch attitude has changed i.e. slowing down, then there has to be some subtle scanner tilt changing to regain the contact.

Crab,

On SAR S61's we routinely go below MSA using a combo of GPS (Rnav) and the weather radar which works really well for coastal mapping.
You can buy moving map now for about 1000 euro which are incredibly accurate and will give you all the SA you need 360 degrees. I know they can be integrated into the S92 displays or bolted onto the glareshield for us who still operate the old stuff.

Give it up, you are not going to get your 360 degree radar! Well, not yet anyway???
Nick.
As my previous question, is the autohover certificated yet?

3D CAM,

The chief pilot of Sikorsky assured me that the SAR autopilot is fully certified (I confirmed that the testing was finished about 6 months ago - Oct, 06).

It includes full FLIR and radar integration, so targets from either can be automatically inserted into the FMS and coupled SAR approaches can be shot from them directly. In other words, if the FLIR shows a target, the grids of that target are automatically inserted into the approach coupler. Thus you don't have top worry about losing the radar/FLIR target when you turn on the approach, I would imagine.
