Aye carumba! How low is that barge???

Have you noticed how close the stinger is to the water? From the photo, it looks like the landing spot is at the same (or even a slightly lower) level than the water...

Or is this just par for the course in PNG?

would it look any a little higher if the shadow from the tail was in the bottom right corner of the picture?:E

Oh yeah. I guess it would...! :ouch:

Good eye, Vorticey

The picture had me fooled too. Some amazing stuff we see on this forum.

Great shots...but....
 

None of them look as small as that time your first instructor said "you got it. Now land this thing anywhere on the airport!" Now that was threading a needle! LOL

Burg Al Arab(or whatever its called)
 

I saw on the box last evening a new(to me that is) TV advert showing several aerial views of some old lady getting into a copter and taking off, what a spectacular ad!

I know this has been discussed before,
but that ad did impress moi!

But heres my technical question for you pro guys,

at that altitude you would need high power to come to a virtual crawl in a very high hover to line up and approach the platform, how quickly and what effect would the platform have on the heli, in that the platform suddenly becomes ground level and the heli is under major power input and very coarse pitch,

Or would you come into a much higher hover over the platform and then let down gently?

Vfr

Either is fine, if you have the power, although if the pad is small then coming into a high hover may make it difficult to maintain references.

I haven't flown to the pad you've mentioned, but landing on a pinnacle the size of your skids at 8,000ASL requires similiar technique.

If power is limited, I'll fly a nearly flat approach. Average power demand is higher than for a steep approach, but a steep approach may require a sudden spike in power that your helicopter can't provide. The mantra is "load up early".

The flat approach also helps with some of the illusions of mountain flying (false horizons, rate of closure, big hand, etc.)

I know some who advocate a steep approach with power limited. There definitely are merits to this. If you can't lose one or all engines and avoid the LZ then being closer to an autorotative profile makes sense.

When I fly the flat approach, I know my single engine fly away speed and commit myself to the LZ if I lose an engine below that speed and don't have room beneath to dive for speed.

Yeah, especially when there are people up their playing tennis:

Catenary landing video
 

Very nicely flown approach and touchdown on that tiny elevated pad...if only I were that good.

what are the dimensions of the pad (aside from small)?

Collective
 

Once you're on the pad, are you still pulling some pitch, not put the full weight on this suspended pad? Seems like you would, but was just curious.

Thanks in advance!
R91

Once over the pad, we keep about 99% of the power needed. You only drop enough power to lightly "stick" to the pad. It is a very difficult thing to do as you are in the middle of a cirque, half a mile from the rocks in each direction and abot 720 feet above the surface below you which is around 4200 feet above sea level. As the linemen disembark or embark, we are very busy smoothly making correction for the weight shift.

If you look at the pictures, notice where the centre of gravity is (directly under the mast), if you were to lower the collective on either type, you would subsequently roll the aircraft backwards off of the pad between the two 267 kV circuits. Now wouldn't that be fun?

Ask a civil engineer about the definition of a Catenary. Not a design that you want to place an unnecessary gravitational force in the centre of. It works out to an exponential relationship.

Thought so...
 

Canadian RH,

I thought I was correct, but just wanted to be sure. Some tricky flying, I must say!

Keep the photo's coming everyone!

Avalanche damage
 

Two weeks ago, a snow avalanche damaged an adjacent tower. They will be busy repairing that over the following weeks or months. I will attempt to post a few pictures.

I have had a few emails asking about the location.

Bleepup,
Post a photo,

I'm a bush pilot in Australia and I've put it into some really dodgey places but that one that one Canunks land on is a cracker.

Sorry i don't have one but i'm try and find out if somebody does.

AZ, I think
 

I love this thread...very interesting

Good work guys :ok:

Thanks,

It has been quiet for a while. Not certain as to why my profile only shows a few posts as I have contributed a lot over the years. New server reset my stats?

CDN RH

Edit: I see it has been fixed. Thank you.

A warm welcome back Bob. :ok:
Some totals aren't accurate, probably because of server changes.


For new members -

It was a photograph of Canadian Rotorhead landing a B206 which prompted me to start this thread in 2003.

A Utah Police AS350 B2 lands atop an outcrop of rock in Washington County during the rescue of an injured hiker

This landing was perfromed by Utah Police pilot Terry Mercer and herewith are some of his comments relating to the landing:

"I had looked at the pinnacle when I first got there, but decided the SAR team would be "ledged" out and have no access to the victim. As I dropped the rope team up high one of the first team members had hiked to the victim and then explored out to the pinnacle and sort of goat-hopped out to it, showing me that they could get on and off of the pinnacle."

"A quick visual of the pinnacle and I knew that it was safe, doable, and the closest site possible. It immediately changed the entire operation from a 1-1.5 day event to a 2-3 hr operation."

"I shut down on the pinnacle on the first landing to evaluate the footprint. The starts were the worst as the ac sort of shifted weight as the blades began to swing."



"It was on that third landing that I got sloppy and landed about 15 inches back and so when Cory got out the aircraft sort of teetered back on the skids. The U-tube footage is when I started it back up and was positioning it forward again. That's why I was alone and landed about 4-5 times to sort of feel out the footprint and determine where I'd be the most solid."

Nice!!!!! :D:D:D

bondu

that's just stupid......:eek:

Rule number one on any mountain course, thou shalt never shut down on a pinnacle.

Glad to see that it worked out at the end of the day. You were lucky, I hope you never attempt a shut down like that again.

I know that most American Airborne Law Enforcement operations, pilots are sworn officers. I have been an ALEA member for over five years now and firmly believe that in such operations the pilot should be only that, a pilot, and his or her sole responsibility is to get the brave folks with the arresting powers home safe at the end of the day.

Shutting down like that to do a secondary duty is something that should be seriously reconsidered. This forum is a great spot to discuss it and learn from.
