Why would they?

Rescue is a minimal part of their job these days, and the largest part is covert surveillance - not something you use a large, noisy and easily-distinguished 412 for!

Maybe there is a change of heart coming?

Why wouldn't they look at a 412 ?

Do you know how many C/T members you can fit in the back of a BK, with all their bombs, bullets and bullsh!t ?

Answer : Not many

sprocket 8th Nov 2005 07:40

... And the 412 would have more appeal for rappelling, no? ;)

SLBAGAGE 8th Nov 2005 09:01

blade root,

How many do fit in? What is not many?
Are you talking about C/T or PAG?
Tell me, how heavy are their bombs, bullets and bullsh!t? or are you collectively referring to "their Kit"
Which 412, standard, SP,or EP?

SLBAGAGE,

Get up on the wrong side of the bed did we?

How many can you carry ? 4-5, depending on the configuration of the a/c, fuel requirements etc. (refering to a BK-117B1).

Yes, I was refering to their "kit".

As to which 412, you are asking the wrong bloke, how much money have they got.......


Kind regards

A little birdy from France tells me they have a new B2 on order:}
So I can't see why they'd be retiering the AStars:confused:

Don't Astars have LTS101 engines?

Aussie's Pigs in Space have Squirrels as the Pork Choppers.

There is definately potential for the introduction of a larger aircraft withing the airwing, although I believe we won't see anything for at least 5 years.

Interesting to note that when originally sourcing an aircraft for the CT role they did in fact have the funding to purchase a 412. It was decided that the long term operational costs of a BK were more affordable ..... especially when concidering the 'here today, gone tomorrow' funding whims of the government. I think anyone would agree, it would be a shame to have a 412 as a hanger queen......

Cheers


P.S The BK is actually a B2 not a B1

No. Those are called Falling Stars:hmm:
AStar and Squirrel are the same thing:}

412 Doors open VNE
 
Anyone know the VNE for a 412 with both rear doors open?

Kim Il Jong 11th Jan 2006 20:00

Re: 412 Doors open VNE
 
Our company policy and limit in our FRC's is 100Kt. (60 Kt to open our close though, then 100)

Re: 412 Doors open VNE
 
Kim - not sure if your company is the same as mine (debrief in Mom's?) but concur with 100kts both open, assuming they are metal doors. Newer, composite, doors are available but caused a few problems when fitted with 'panting'.

Re: 412 Doors open VNE
 
Remember that the flight manual makes note of the type of seating that is installed in the aircraft.

As said before - 100 kts doors open and 60 kts for opening and closing.

Re: 412 Doors open VNE
 
1. Check the flight manual in the first instance regards the model type etc.
2. The type of seating installed (cushions!), as mentioned earlier will determine if you can fly/open them at all.
Use 60Kts maximum door opening and closing speed.
I have a feeling that the flight manual states the following;
80kts Asymmetrical open door(latched)
100kts Symmetrical open door (latched)

Bell 412 rotor track and balance
 
Hello, any experts out there willing to share experience on Bell 412 main rotor track and balance. (Despite using the RADS system recommended by Bell I find that the task is much more time consuming than on other helicopter types.)

SASless 24th Jan 2006 17:22

Unless maybe a recalcitrant Hughes 500D/E is considered!

Matthew Parsons 24th Jan 2006 17:44

I don't want to label myself an expert on it, but I have flown a few T&B's on the 412.

Be very precise with the ground track and then the hover track. With those two regimes done well, the rest should follow. Then focus on the forward flight. Try to get all regimes on each flight. Also, remember to compare the results of each flight to make sure you're not going back to an earlier condition.

It can take a long time, but it does give you a smooth ride that tends to stay smooth for many hours.

Matthew.

Good luck, 412 dynamic balance can be a real pain. Before you start flying do a very close inspection of everything from the transmission mounts up. Check all of the control rod bearings, swashplate bearings and bridge dampers very close. Water in a main rotor blade can cause major headaches, you can spend time balancing just to have the water get out of the blade and put you back where you started.
