engine failure over the mountains
 
i just discovered a video on the internet and doesn't seem to be old yet. well done and watch out ...

You might need a couple more posts before you can attach links or contact the mods and ask them to do it on your behalf

This link should work (and it seems to play an ad first):

Here is the actual video from the BC Helicopters Youtube channel:
The title is misleading, it's a simulated engine failure.

BC Heli always has entertaining videos. If they were leasing my Cabri I’d grumble about the auto onto rocks the size of a baby’s head, but small quibble​​​​​​.

When he’s flown another “8,500 hours” he’ll realise why that was foolish.

Fareastdriver 18th Jan 2020 13:25

If I landed on a river bed after an engine failure you could bet your bottom dollar a dam would burst two miles upstream.

SASless 18th Jan 2020 13:36

FED,

Ever the Optimist aren't you!

As are most real helicopter pilots!

Hmmm - no mention of diagnosis to confirm engine failure rather than partial power loss, no mention of looking to restart the engine, no mention of wind direction and he made a power recovery to a zero speed landing and stated the real EOL would have been exactly the same.......... Not likely to get an Academy Award nomination for the acting either:)

Robbiee 18th Jan 2020 16:18

Engine failure in the mountains,...hmm?

So, which of these guys will resort to cannibalism first?:oh:

Two's in 18th Jan 2020 16:25

I could have rebuilt that engine in the time he had to get down from FL nosebleed.

It’s good what it was made for: to describe the capabilities of a helicopter following an engine failure for the ignorant layman.👍

EXACTLY 🙄

SASless 19th Jan 2020 01:36

Actually.....it would also work for ignorant helicopter pilots as well.

Exactly Crab....zero diagnostics assessment of the engine, no attempted restart! I'm sure this flight pathwas rehearsed for the voodoo shoot. Having suffered a real engine failure in the Mountains.....it sure ain't fun & bloody serious if You are gonna have any chance of survival :ooh:

so an ignorant layman will understand 'stretching the glide' - a layman might like to know how quickly they are going down or what the difference is between an engine failure and rolling off the throttle.

They seem nice guys but it was just a piece of FIGJAM video with not much point to it.

Spunk 19th Jan 2020 12:35

... but the layman will understand that an (simulated) engine failure does not automatically mean that the helicopter will drop out of the sky like a rock.
It all depends on the perspective you (want to) look at something.

Please enlighten us: What is the difference?

Rolling off the throttle - "See we have a nice glide going here, looks like we can gently set it down on that beach over there,...beautiful day isn't it?"

Real engine failure - "Oh ****, oh ****, oh ****, oh ****, oh ****, oh ****, oh ****!"

SASless 19th Jan 2020 17:02

Having had one of those actual engine failures coming off of a mountain just before dark one night up near Tok, Alaska....I can confirm it was nothing like the video.

I somehow got it right....and landed the helicopter without a mark on it in the middle of a forested area with no clearly discerned landing areas.....but it worked out well in the end.

Note: For those who can only talk about what it might be like....when it all goes quiet from the nine bay....the adrenaline level goes up several orders of magnitude depending upon the numbers of engines one has left that are working normally.

When that number reaches "Zero"....and there are no nice clear options....you are in the middle of nowhere....and the climatical conditions do not favor having a picnic and sleep over outdoors.....the video does not do justice to reality in that case.

MightyGem 19th Jan 2020 19:11

Used to do similar with students on Army Pilots courses over Mt Snowdon. Fly past the restaurant(east side IIRC), Practice Engine Failure Go! Then down the valley.

Sometimes it worked, sometimes it didn’t. Entry height and windspeed/direction were the deciding factors.

Firstly the amount of Nr decay which will need a very prompt lowering of the lever and a significant flare - if you have speed - if you push the nose down quickly you will decay the Nr further - none of this happens when you have a pre-meditated throttle chop like the one in the video.

I am also reliably informed that the recovered Nr will be lower when there is no assistance from the engine - even at idle it is producing power - and so the RoD is likely to be higher.

The main point is the surprise and disbelief and the likelihood that it will happen at the most inconvenient moment rather than at a height and speed where an easy glide down to the valley is set up prior to the throttle chop.

If your sphincter muscles stayed fully relaxed, it was only a drill...

SASless 20th Jan 2020 03:24

Forget safety harnesses....just a trailer hitch ball would work during the real thing!

[email protected] 20th Jan 2020 06:40

Sas - that's a mental picture I didn't need:)

GrayHorizonsHeli 20th Jan 2020 12:51

do you go in for a fitting measurement on what size ball you need, much like you do for helmets and flight-suits??

SASless 20th Jan 2020 13:52

They come in several sizes.....now I have heard Crab would need a large one from the way he has been described here over the years by some.:uhoh:

[email protected] 20th Jan 2020 16:10

But only when I'm properly scared - half a crown, sixpence, half a crown, dustbin lid!

This post above nails it. Mine wasn't over the mountains.
When it happened I was stunned for a few seconds...I simply didn't think it was real and the NR decay was faster than I remember seeing in training.

If the EOL in the video was real, the voices would be a few octaves higher. Nice video though.

'FIGJAM' :ok: Absolutely!
