A little Forane, a little Nitrous with 2 X's the O2, a little Versed, a
little Fentanyl, and a wallop of Porpofol to start! Of course a slug of
Norcuron so you will be still while we cut and Wallah...you have anesthesia!
BP goes up...a little more Forane...BP goes down...a little less Forane. Of
course all with care to follow the volume in the tank. That's where a hooter
hose and a big bore IV come in handy. Ringer's and Lasix can fix most volume
problems that decreasing the Forane does not. Once out of the PACU...you
are the surgeon's problem!

Rico, did anyone mention oxygen is not a good thing?
Just wondering if you needed further advice. 
Lots of urban legends on the YAK list. For example, I am now going to pick on Doc some more since it is a hobby of mine on occasion.
Doc, when was the last time you personally filled your main air bottle with nitrogen and then tried to start it? I mean personally, not a story from others. I don't know what the heck the deal is with this, but I have now used nitrogen on three M-14's and they started easily. One in a YAK-50, one in a YAK-52, and one in a Sukhoi 31.
The reason I bring this up (again) is that most airports don't even keep nitrogen at that kind of pressure handy. Compressed air, yes. Dry pumped nitrogen, no. At New Bern NC, I am the ONLY person with it. Including all the shops on the field.
Personally, if I am not going to fly the YAK for awhile, I purge all the air systems with nitrogen and then fill them tippee top. Never had a problem what-so-ever.
Mark

DO NOT PUT OXYGEN in the air system! UNLESS YOU WANT TO BE BLOWN UP IN A Literal SINCE when you first start the plane!. Use compressed air only. Nitrogen will work but will in most instances not start your engine when you get to that point.
NO OXYGEN in the AIR TANKS! YOUR LIFE DEPENDS ON IT!

OK, being a complete novice here...I have no idea what "25 atmospheres" is. Will I know how to achieve that when I hook up a welding oxygen tank to the system? I've only dealt w/ PSI. Thank you - and so sorry for the naive questions.

More undesirable than damaging because it shakes the heck out of the
airplane while on the jacks. Air pressure? I think I already answered
that. On an average of all 52's a minimum of 25 ATM's will be needed
for any retraction.

You have to have jack points to screw into the wings (behind the main
gear legs) and at the base of the firewall where the lower cowling
attaches. They are 14 mm threads. Jill has them available. I've
attached a photo of the nose jack point. There are two of them...one on
each side of the cowl. BE VERY CAREFUL with the nose jack because the
nose wheel fork has to clear the jack AND the ground when retracting and
extending. Use a 3-legged jack for the nose wheel and make absolutely
certain the wheel assembly will clear the legs of the jack before you
swing the gear. Also, make absolutely certain the nose tire will clear
the ground during the swing up and down. Measure from the pivot axle
bolt (nose wheel mounting point) down through the wheel axle to below
the tire and swing the arc back and forth to make sure the wheel clears
the ground during the retraction. Otherwise, if the nose wheel touches
the ground in any way during the retraction, it will push the airplane
off the nose wheel jack. That would be a real mess.
Once the main system gets down to about 25 Atmospheres you may have
difficulty doing gear retractions and extensions. Understand this Rico,
the lower the pressure in the main air tank the harder the harder the
gear will slam into place when doing retractions and extensions. The
reason being - the air pressure in the actuators acts as a "shock
absorber" on the opposite side of the actuator. ie: when doing a
retraction, the air pressure in the DOWN side of the actuator is
expelled from the actuator as the gear is moving to the UP position and
vice versa. Gravity contributes to the slam when the air pressure is
low in the main air tank and the gear is moved to the DOWN position.

Yeah and most airports don't have Sharader valve adapters either. That is
why when I go XC (rarely these days) I carry a pony bottle along with my
Stage I SCUBA tank adapter/ refill setup. I can always get air from a Dive
shop or a fire station. Never had to yet to date. Maybe it is good
maintenance or just plain blind luck. As for using N2 to start or fill my
tanks with...have not even given it a thought. The O2 in the tank
..definately thought about that but have not tried that either. Figure 50
ATM of O2 fired off would be a bit more schrapnell than my ol body could
survive.
So answer...Compress Air Yes,
Nitrogen - No,
Oxygen - Not NO BUT HELL NO! I am making
nominations for the next Darwin Awards if there are any takers/experimenters
wanting
to try?!!

Of course when you fly in your handy-dandy F-16 Fighting Falcon, nitrogen is all they use.
Hmmm.

Mark,
I've never noticed any difference starting after charging the system
with nitrogen. The first time I started it with a pure nitrogen charge, I
pulled it through, then primed it, then pulled a couple more blades to pull
the fuel charge into the cylinders. It started as usual on the first
compression stroke before it had time to get the nitrogen into a cylinder
through the start valve. Even if it would start harder keep in mind that
every cycle of the gear, flaps or brakes decreasing the blend of nitrogen to
air as the air compressor replenishes the system.

If you use oxygen rather than air you could well blow the U/C off the aircraft.
DONT USE OXYGEN
Use only inert nitrogen or air.

The Marines may like the knots on their heads and the headaches when they
wake up but the rest of the population of patient's don't like to pay for
brutan anesthesia. Understand the Marine thing though and we will do
everything we can to make the ride lumpy! :^))

NO NO NO NO NO NO NO NO NO NO NO NO !!!!!!!!!!!!!!!!!!
DO NOT USE OXYGEN!!!!!!!!!!!!!!!!!!!!!!
IF YOU USE O2 YOU COULD IGNITE THE OIL IN THE LINES!!!!!!!!
Normally one uses compressed air from a SCUBA tank. If that isn't convenient you can use N2 (nitrogen). N2 is totally safe and eliminates any chance of fire but can (under some conditions) make your engine hard to start.
As for atmospheres, PSI, and kilograms force per square centimeter (kgf/cm^2) here is the skinny:
- The stock gauges read out in kgf/cm^2.
- 1 kgf/cm^2 is very close to one atmosphere, enough so that, in this case you can use them interchangeably.
- 1 atmosphere = 15psi.
- 50 kgf/cm^2 is approximately equal to 750psi.
Hopefully this helps.
I am beginning to get the feeling that you might want to find someone to help you who has a bit more experience.

OK, being a complete novice here...I have no idea what "25 atmospheres" is. Will I know how to achieve that when I hook up a welding oxygen tank to the system? I've only dealt w/ PSI. Thank you - and so sorry for the naive questions.
NO NO NO NO NO NO NO NO NO NO NO NO !!!!!!!!!!!!!!!!!!
DO NOT USE OXYGEN!!!!!!!!!!!!!!!!!!!!!!
IF YOU USE O2 YOU COULD IGNITE THE OIL IN THE LINES!!!!!!!!
Normally one uses compressed air from a SCUBA tank. If that isn't convenient you can use N2 (nitrogen). N2 is totally safe and eliminates any chance of fire but can (under some conditions) make your engine hard to start.
As for atmospheres, PSI, and kilograms force per square centimeter (kgf/cm^2) here is the skinny:
- The stock gauges read out in kgf/cm^2.
- 1 kgf/cm^2 is very close to one atmosphere, enough so that, in this case you can use them interchangeably.
- 1 atmosphere = 15psi.
- 50 kgf/cm^2 is approximately equal to 750psi.
Hopefully this helps.
I am beginning to get the feeling that you might want to find someone to help you who has a bit more experience.

The normal air pressure for the system is 735 PSI which equates to 50 atmospheres. Some debate here on nitpicking bars and atmospheres that I will avoid. |
Bars are atmospheres ... or were. Later they decided that one standard atmosphere was 1.0132 Bar. But the Bar was intended to be a standard atmosphere. I doubt anyone's gauge has the necessary 1% accuracy to make the difference significant tho'.

It reads in single digits, like 1-7, and you multiply that by 10 to get the actual reading. So when it reads 5, that means 50 which means 50 atmospheres, which means .... 735 PSI.

I am going to get nit-picky here. The gauges in the Yak and CJ are calibrated in kilograms of force per square cm (kgF/cm^2) not Bar and not Atmospheres. Again, the measurement is really close, with 1 Bar = 1.0197 kgF/cm^2 so all these are within 1% of each other making the difference inconsequential for our uses. And it is close enough to use 1 ATM = 1 BAR = 1 kgF/cm2 = 15psi.
But the official measurement is 1kgF/cm^2.

One I started passing a kidney stone landing at Heathrow. By the time I got out customs, I was on my knees in pain. A female Bobby called the medics, (Mick & Mike) who quickly had me breath Nitrous Oxide and O2 (50%). Three breaths of that and NO PAIN PLUS I WAS ONE HAPPY CAMPER! Back here in the states, same problem, different kidney, 10 years later, the medic was trying stick me in slow and bunching ambulance to give me morphine. :45 later (we stopped for the night fright train though town) just as we pull up to the ER door, he finely injects me.

A little Forane, a little Nitrous with 2 X's the O2, a little Versed, a
little Fentanyl, and a wallop of Porpofol to start! Of course a slug of
Norcuron so you will be still while we cut and Wallah...you have anesthesia!
BP goes up...a little more Forane...BP goes down...a little less Forane. Of
course all with care to follow the volume in the tank. That's where a hooter
hose and a big bore IV come in handy. Ringer's and Lasix can fix most volume
problems that decreasing the Forane does not. Once out of the PACU...you
are the surgeon's problem!

Trust me, it is an art to hit a vein in a moving ambulance.

Having nothing to do with this in particular ... Let me tell everyone
THIS story.
| Quote: | From direct experience, be aware that the U.S. FAA reads this list.
Most people will say: "So What?" and by and large that is true, and in a
|
court of law, if you pay the legal fees, you can win in that regard.
However, the FAA considers LIST postings to be "Statements Made in
Public". This is in my mind pretty much B/S, but it is what they are
saying. Trust me on this.
That said, a long time ago "a friend of mine" put on his medical form
before a flight physical that he had once had a kidney stone. Well, the
proverbial horse manure hit the fan. He had to go get a CT scan to
prove he was stone free. Since there was no current medical malady,
this was not covered under insurance. He then had to go to a Urologist
and get a signed statement saying he was "totally stone free", and this
was no simple matter either. This gent had ONE kidney stone in his
entire life... after spending a year in Desert Storm by the way.
Imagine that.
It gets worse.
Every time that same gent went for a medical after that, the "Doc"
wanted the same procedures repeated.
Worst of all, checks with FAA medical authorities confirmed that this is
"standard procedure".
I would be the last man ever to suggest telling anything but the truth
while getting an FAA Flight Physical.
