This video is doing the rounds. Speaking as someone who never has and is never likely to be in a situation like that, it certainly looks extreme in skill and the act itself.

Can't say i'd fancy the walk below the blades in that situation.

Actually much easier than you would think.

Apply the Parking Brake....Touch the aft gear down....apply two inches aft cyclic....control heading with Yaw Control Pedals....control pitch attitude with Thrust Lever (Collective)...and wait till every one is onboard....vertical ascent using Thrust Lever and off you go.

Much easier than trying something similar in a single rotor helicopter.

Lots of talking between the guy on the ramp and those up front I guess. :ok:

It is a "Crew" manned aircraft.

The guys in back are very much part of a successful and safe flight.

I still have lunch now and then with three of mine from Vietnam days.

Mmmmm ...


......I still have lunch now and then with three of mine from Vietnam days. ....

I REALLY like that you do that ... :D:D:D:D:D

I am just glad that we can....and do.

One of the guys organizes Vietnam Trips.....have done two with him and planning a third.

Last trip we visited the places were we lost guys.

One place was where we worked with the Aussies.

Amazing the emotions you can keep bottled up for 30 plus years.

That makes these friendships all the more valuable.

One of the guys I meet with is a Land Developer....and in one Sub Division he built....all the streets are named for guys we lost.

One of the guys is a German Immigrant, who has a very strong German Accent to his English....who we immediately dubbed "Frenchy" all those years ago....and he still goes by that name today.

There is a bond that gets formed when you share great risks together for a year or more...that lasts forever.

Thanks SASless.





That video is just awesome.

It demonstrates the skill of the crew and what can be done when needed. Also makes it harder for the enemy to dick(booby trap) potential landing sites when the aircraft can land vitually anywhere.

I know loads of you think the S-61 is the queen of the skies but in my humble opinion who has never flown anything bigger than a AS365 the chinook is the real monarch, maybe it's because I knew the chinook from childhood and we all know how childhood colours us.LOL

I am a Chinook Pilot....once you fly that old girl....you are "Hooked" for life.

I would give a yard of my Trigger Finger to fly the CH-53E....as that must be some helicopter as well.

But...once you fly a Tandem Rotor machine....and grasp its advantages....single rotor helicopters are just so much more limited in what they can do compared to the Tandem Rotor design.

The Tandem is easier to fly, is more stable, has handling characteristics that make it a dream to fly. Add in the four point landing system on the Chinook and it really gets interesting.

Nope....I loved my Huey, the S-58T, the S-76, the BK and BO....even the Alouette III and Lama....but hands down....I am a Hook Man heart and soul.

She scared the dickens out of me on a couple of occasions but at the same time she always got me back on the ground in one piece even when she herself and me were a bit tattered from getting shot up, getting hit by shrapnel, and having a huge log bounced off her side in a Land Mine explosion.

The Chinook is the Queen of the Skies without any doubt.

SASless, like Brilliant Stuff and spin wing said, I'd like to add my thank you too.

A few photos of my Darling!


This one is one of the first ten to be delivered to the Army and started life at the Army Aviation Test Center and later found herself assigned to Hanchey Field where the Conversion and Flight Instructor Training took place for the Chinook and other Cargo Helicopters. This old Lady is in the Army Aviation Museum at Fort Rucker and I flew this one when went through Conversion Training and later when I did my IP course and first instructing on the Hook.

This is one of the 160th SOAR MH-47's....that is the unit that flew the SEALs in to get Bin Liner.

SASless, i've heard that the Chinook can suffer from a 'purpoising' effect... have you ever experienced it?

Now that is a good idea! I hope it catches on.

Not sure what you are referring to....but flying into a Thermal can sometimes feel like driving up onto a street curb. The forward head hits it...and the nose pitches up ever so slightly then the Aft Head hits it...and the rear end comes up that wee bit too.

SAS,

The CH-21 had some delta 3 coupling built into the forward head ( upward flapping begets a reduction in blade pitch ) which was intended to improve short term pitch dynamic stability in turbulence. I always assumed that the CH-47 included same, but don't recall ever asking anyone.

Does a dual rotor machine autorotate the same or similar as a single rotor?

SASless

Pretty much the same...without the yawing caused by the changes in torque/Collective (Thrust Lever) movement as in a Single Rotor Helicopter.

Porpoising was cited in a fatality of an Aussie who fell from the ramp in Afghanistan. Aussie accident (http://www.flightsafetyaustralia.com/2015/07/saturation-confusion-impact-the-wild-ride-of-brahman-12/)I believe the AFCS got saturated and the pilot ended up in a PIO. You could probably induce something like that it you made rapid back and forth cyclic inputs above a certain (crossover) frequency

The BV234 in auto floated like a thistledown from what I remember. SE landings were a nose high run-on flaring just like an aeroplane that used a fair distance to stop. What was the full auto technique though, run on again or flare-check-level?
Flying the ILS backwards (from ground upwards) was a favourite trick in the sim.
To demonstrate how easy it was to fly my mum flew a circuit from rolling t/o to rolling landing without me touching the controls (coaching all the way of course) - agree with SAS, queen of the skies without doubt, wish I'd been fortunate enough to use the military version too.
The only vices I recall was a tendency to slide on slippery surfaces (only the aft stbd wheel steers) necessitating two wheel (nose high) taxi on ice and snow which was fun but created some downwash, and a known weakness of the aft gear especially to side-loads I think. Anyway, they were considered breakable and were to be treated gently, unlike the rest of the thing. They take one heck of a load, those aft gear legs.
Max translational lift occurred in sideways flight to stbd so in timber harvesting Columbia would hook up a translational load (too much to lift vertically) on a hillside, move well to the left of it keeping the long strop tight and then max power sideways to the right hauling the load off over the valley with translational lift and transition to forward flight. Probably a vid on youtube somewhere.

I was on an exercise with a Chinook a couple of months ago. It's been a lotta years. My colleagues were confused by me describing the Chinook as quiet. However, none of them fly in the S-92! :E
