What’s the highest fellow pruners have flown in a helicopter.

I once flew a 206 to 11,500 and an R22 to 6,000 feet.

Have to say I didn’t like it waaay up there :uhoh:

Flew over some 10,000 ft mountains when I was in the US, landed at Big Bear at 6000+ ft. It didn't feel "way up there", since we were quite close to the ground, but I learned lots about density altitude, being hot and high in underpowered helicopters, etc. Lots of fun too. :ok:

Used to throw the beer into burlap sacks, wet them down with water.....stow them in a breezy place......then up to 12,000 feet agl in a Bell 206 and Alouette III. Was in my twenties then.....would drink hot beer now! Don't know if I am wiser or just more openminded about adversity.

I've taken both a Bell JetRanger (TH-57) and a Boeing SeaKnight (aka, the Phrog CH-46E) up to 10,000 - maybe a little more :) - but Navy/Marine Corps limits are 10,000 ft without supplemental oxygen. I think the Army guys are allowed to 12,000 or 14,000 ft. Curious that the different branches of the services have different altitude restrictions.

OH-58C at 10,000 with the doors off over Ft. Bliss, Texas. This was about 1 month after flight school and only there for a moment just to check it out, then a very long auto, with a slow, high power recovery.

When I was in Nicosia with my father, during the mid-50s, I seem to remember an RAF Wessex Whirlwind trying for an altitude record over Nicosia airport. Can't remember the altitude, although 20k feet seems to nag me, or even whether it was successful.

Can anyone help?

In forward flight, regularly to 17000 feet in tests, in Comanche, S-76, H-60. Once to 21000! Air is skinny up there.

Landings and H-V work at 11,000 feet, engine cuts and autorotations.

Many years ago the Raytheon Company in Santa Barbara, California proposed a satellite that did not require the use of a booster rocket to raise it to orbit.

The satellite employed helicopter rotors that were turned by an electric motor. The motor in turn was powered by radio waves.

It was envisioned that the helicopter portion of the assembly would raise the satellite to orbital altitude (Approximately 22,000 miles) and then a small solid rocket would bring it into a circular orbit.

That's why an electronic engineer should never work as an aerodynamics engineer.

Was it Pierre Boulez who took a Llama up to FL460 in the early 70s? The story I saw said it had been stripped down to save weight. The canopy entirely frosted over in cold. When he eventually lowered the collective the engine (never tested at that height) flamed out, and with no relight system he started the world's highest ever autorotation. Of course he couldn't see anything, and tried to keep straight by reference to the sun. He knew it hadn't worked when the sun was level with the cockpit floor, but he pulled out of it, the frost went at lower altitude and he landed successfully. Unless anyone else knows any better, and it wouldn't surprise me.

Most posters have mentioned how scary it is. OK, neophyte's question time, apart from heli pilots' natural tendency to worry when above jumping-down distance, what is it that worries you? Controls near their stops? Unexpected divergences?

2nd Sep 2003, 03:56
Nic,
You were discussing the pros and cons of the compound helicopter in a separate thread. Does the compound have any ability to go higher and does the wing interfere with an autorotation? Finally, do you think the Marine Corps is going in the right direction with the MV-22?

Twice went to 18500 in a Wessex Mk 5, first time over Cornwall at night, the second at Labuan, Borneo. In Papua New Guinea we used to land a Hiller 1100 on mountain tops for P & T, I think Mount Wilhelm was around 14000, which is the highest in PNG.
Never used oxygen; don't have to when you are young, do you???:O

Several times up to FL 180 to test and to use special surveillance and observation equipment inside and outside (hooked pod) the helicopter. During the flights the ship was sometimes heavy overloaded and needed more than 45 min to climb up to the end level (take off in 1000 ft). Climbing only at Vy and level flight 20 percent around Vy. Never used oxygen, but we (the pilots) were all pressure chamber tested. But as a helicopter driver you feels so alone at such an altitude and good ol earth is so far away...

Remember me on the up to 10 minutes autorotations with the very cold cabine due to the idling engines.

12,000' in a Bell 47 Sioux a few months ago as an experiment.

Nigel's escapade over Cornwall reminded me of the height climb in the RN wings syllabus, when we were taken to 10,000ft (gasp!) in a Whirlwind 7 to be show effects of controls. 1 hour scheduled for the sortie, parachutes, the lot, out of Culdrose. 30 minutes for the old girl to stagger up there, then various flight regimes, finishing with a demonstration of the stick shaking as retreating blade stall was approached. Long, long auto down.

Years later I found the instructors were just as nervous as us, and a surreptitious kicking of his cyclic was the stick shaking demonstration!

Operate all the time up around 9-10,000 ft in the Oz Alps, don't even think about it these days ;)

15,000' a few times doing tests in a EH 101, oxygen & chutes etc.

As an aside the Hypoxia course at Boscombe Down was great fun, just like getting drunk, but with no hangover. And I now know that I can't do many jigsaws at 25,000' without oxygen!

NickLappos
3rd Sep 2003, 09:24
46driver,
A compound should have a slight advantage on altitude operations, since it cruises in autorotation, and uses the rotor in a much more unloaded mode, but it generally swaps the lower load on the rotor for more speed, at the same degree of stall. This means that it should have the same altitude characteristics, but should be 20 to 40 knots faster, or for identical speed, should go a few thousand feet higher.

regarding the V-22 and USMC missions, the customer choses the aircraft's properties and we build them. Imagine the way you'd treat a swimming pool designer if he started insisting that you didn't want the deep end over there !

Time will tell what the V-22 can really do, so far, the glowing wishes of the salesmen has not met the cold light of reality, but the woeful predictions of the naysayers hasn't been realized, either.

As a former test pilot, I flew many different models up to and above the published flight manual limits (normally 18,000 ft.) and just like Nick Lappos, we did various system failures while flying at the CG and speed limits.

Always had parachutes above 12,000 due to the possibility of a fire or failure that would require a quick landing, which you can't do from way up there. Also O2 above 12,000 ft.

Some locations where we did the testing, we had commercial airliners below us as they descended for landing. ATC would call, "traffic is a helicopter above you at FL180", which got some interesting responses from the airline crews over the radio.

5' 9" officially. [And 12000 feet without oxygen in a Wasp]. So that makes it: 12,005 and 9" in total. (I was standing up at the time).
However this was an ICAO answer based on PA. The actual temperature was colder than ICAO @ 12000. And the DALR was a little > than 1.98/1000' so the DA height was: 14,569'

TC as you know there is always some smart arse but I could not resist.

You've got it completely wrong this time. Pofman is 100% British, was one of my RN instructors (he sent me on my first solo in a Whirlwind 7), along with myself and a few others here, was one of the founder pilots of BCalH when he was flying Bell 222s and Bolkow 105s for the Met Police. He was an ab-initio instructor at the Bristow Training School in Redhill and has impeccable credentials.

The high alt airtest for the Scout and I would imagine for the Wasp went to around 12.000.
We used to wear parachutes as they reckoned if we caught fire at that altitude it would be largely ashes that hit the ground. There was no parachute training provided. I suppose the theory was that 12,000 gave you plenty of time to work it out on the way down!!!!!!!
Probably right as well.

Nothing worth mentioning in my experience. But, I must know from the R22 drivers posting above, did you lean the mixture to get enough power to get that high? In my training at 1000 ft. MSL, I was taught to push mixture full-rich, set-it-and-forget-it. The thought was that if you leaned too aggressively and killed the engine, there was no flywheel (read "prop") to keep it spinning for a bit, things could go bad too quickly, so just fly full-rich full-time. I would think that would be too rich to have sufficient power to get much above 10,000 ft.

20000ft in an Alouette III without oxygen on my 21st birthday. Couldn't make 21000ft and was feeling peculiar in the head. Must have been even more stupid then than now to attempt such a thing. Controlling rotor rpm in autorotation at that altitude is scary. The controls seemed to be very poor in response. I scared myself witless.

Some people think that the air gets thinner at altitude, but it doesn't.

It gets thicker.

Just look at the aircraft that fly at each level. The machines down low are flying through thin air, and are blunt and knobbly with lots of drag-creating devices hanging off.

Those that fly at high altitude where the air is really thick are pointy things with sharp swept wings.

The sky gets dark at altitude because the light can't get through the thick air.

Spaceships need lots of power to push through the thick air to get into orbit, and once up there, they just skim along on top of the air layer.

So, helicopters have trouble getting to altitude because the rotors hit the thick air and can't get through it. Like stirring a treacle pudding.:8

We had a pilot once, turned up over base at 5,000 feet plus, telling us all on the radio how fantastic it was way up there. You might say that he was reminded of the seriousness of a fan drive failure and that it would have meant a full down EOL. After a few curse words he descended.

Years later I happened across a remark he had authored either on a blog or thread such as this as to how he had thought is was great bein' way up there and also as high as a kite on dope. So yeah, how high was he?

I sincerely hope that he looks back on that particular incident with some serious misgivings of his own sanity, if not some well deserved shame.

Ascend Charlie has nailed it, he was right up there in the thick airspace.

toptobottom
3rd Jan 2013, 11:07
AC - that makes perfect sense to me. That explains why I get out of puff when I'm exerting myself at high altitude; it's all that thick 'treacley' air slowing me down.

Maybe that's also why Ethiopian long-distance runners are so good? Suddenly they're down from the mountains and in the thin air: less resistance = faster speeds.

And, as if even more evidence was needed, that explains why asteroids burn up as they hit the thick air next to outer space. You hardly ever see an asteroid burning up in the lower atmosphere - there's no resistance as the air's too thin. :8


13,000' in an EC120 for me, no dramas and the 60kt tailwind was useful. The one that made me decide enough was enough was 10,000 in an R44 - although it was still climbing nicely and had power in reserve, it just didn't feel comfortable...

Fastest rate of Climb ever experienced was "0".....flew off the North Rim of the Grand Canyon in very hazy conditions....went from 100' AGL to just shy of 6,000' in about 0.2 seconds....and that is FAST...faster than some rockets!!

Friend of mine was flying along in a Dauphin at FL300, but then his turn for the chemical toilet came up in the C-130 and he got out.

Landed on a Swiss mountain top at 12000. Was surprised when the instructor said it was OK to shutdown(used to Gazelles with, I think, an altitude limit of 10000 for start).

10k agl last year with an underslung glider for James may's toy story. Seemd rather high with no door on looking down
Know what you mean. The only time I've been reall uncomfortable flying was in a 206 at 10000' with no doors and moderate turbulance. :sad:

with an underslung glider for James may's toy story
Wondered if a ppruner was involved.

Um.....I have sat in the cockpit of a genuine Japanese Zero fighter....at -140 feet or so in Truk Lagoon.....to show some perspective here.

Corsair for me, just off Koko Head, Oahu in 110'. 'Sat' wouldn't really be true, as the seat was long gone.

Have also landed an actual flying helicopter offshore about 120' below sea level, but that ain't what we're talking about here.

Yess been there :p Flight level 360 in a Hughes 300C.. pretty funny, the captain on the B747 Cargo asked me to check the altimeter on the Hughes :E Didn´t fool me though, told him it would probably show 7-8000 feet.

Fred North | World Altitude Record – 42,500FT (http://www.fred-north.com/?page_id=338)

This guy´s been up pretty high.

I have myself been to 12500´ and only about 1500´ agl (can´t trust the radalt over ice) in a B212 over the Greenland icecap.

The 212 does´nt mind the altitude, Vne just about goes down to normal cruise speed anyway.

Just before the mighty Bell 47 Sioux was retired from 'operational' service in the RNZAF (circa 1986), an attempt was made to reach the promulgated service ceiling (20,000ft). Our AvMed folks stipulated portable oxygen (of course) and two pilots, which cut down the odds slightly. Still, they made it to 19,600ft PA. Bruce/Pete: If you're out there, you may still have the photo.

Regularly cruising between 7500ft - 10500ft in an R-44 in East Africa; 12500 ft up the slopes of Kilimanjaro a few times - collective tucked in the armpit, that is. Vibration is rather annoying at anything more than 65kts though and controls become somewhat insensitive up there, too.
Highest LZ in a 44 was ~7600ft (some 10,000ft DA) on a crater rim with 2 pax and 24gal of juice

That's interesting so I'll bite, how or more particularly where did that happen?

In an Chetak ( HAL Allouette III ) level flight at 25,000 ft in the Himalayas . In a Cheetah ( HAL Lama ) landings at 20,000 ft ISA + 30 about 23500 ft density altitude .... and it amazes me that we don't run mountain flying courses for the others in India !!

10k AGL on a beautiful gin clear day, in an R22. A little weird but the most amazing view. The earth looked like a 250 thou map laid out below.

How about turning the question on it's head - How Low Have You Been (legally!)?

This is 250' AGL and the QNH is set correctly ;-)

Fly safe in 2013, everyone.

The lowest I've ever been was 0' AGL. Not very pleasant, I can tell you; I felt nauseous and dizzy :E

It all started in 1969 when assigned to an ARA unit. We used to hold at 500 to 6000 waiting to prep LZs for the slicks. Standard Purple Heart issued for facial rash from wearing oxygen mask.

Routinely filed from 8500 to 11500 in the guard and reserves to take advantage of winds aloft (OH-58, UH-1H). About the same altitudes in the S76 offshore GOM. 15,000 just for grins over Leeville, in a 206A. Max altitude in an S-62 was 1500 feet and 73 knots. Retreating blade stall buffet at 74 knots. 41,000 in a Citation 2. Reminded me of the S62 ride.
