High Altitude Flying and using the Oxygen System 

+Verrückter Wissenschaftler Glad you enjoyed! I enjoy the high alt stuff. Pretty fun in a piston aircraft.

Glad it was helpful!

Have fun!

+TechiPhoneGames Thank you! Glad you enjoyed it.

Bruce McNair Welcome, Thank you for watching

Very welcome!

It depends on the plane and the current weather conditions. Most of the time you can fly at 25k without issue but you always want to be aware to need to keep an eye on your temps.

Yes this aircraft had an issue with the unit that opens the oil cooler which is supposed to happen at 180. It's was addressed at the service center when I landed after the flight. Normally they stick pretty close to the 180 in flight.

Thank you for watching!!

No not really. I used to get alot of questions about the plane a few years ago because the controllers were surprised at its capability at high altitudes. Now its pretty common and I rarely get asked anything.

This aircraft actually ended up having an issue with the oil cooler that had to be fixed after I landed. It's normal to see the engine run a little bit hotter in the FL's but still well within the normal range. Normally I won't go into the FL's just for the extra true airspeed, I go for the tail winds. True airspeed may be 15 knots faster where tail winds may be 100kts

Thanks Mark, makes sense and appreciate the reply, got one other question id love to get your feedback on that ive been getting mixed answers from the Cirrus community, don't want to clog up this channel so do you have an email address i can ping question to ? thanks, Simon

+david barker to refill the Cirrus 77cuft tank I have seen it run anywhere from $25-$70. Pretty much any FBO can or have the local shop do it. All jet have back O2 tanks so it's very common.

Holy.....How high was he flying?

The tank is behind the baggage area bulkhead and has a filler port in the aft wall of the baggage area

Hi Remington, It's more than just functioning. In the air you are required to use both fine motor skills and critical decision making. Both of which have been proven by numerous studies to be negatively affected at altitudes as low as 6,000MSL.

Yeah I totally agree with you there. I've seen people get full altitude sickness at 8,000 feet. Acclimation does make a difference like the heli rescue teams on and near mont-Blanc for instance fly to 14,000 ft + consistently with no oxygen. I think the 10,000 limit is a good rule of thumb for most people to be on the safe side, even then sats can drop below 90

You are absolutely right that altitude impacts everyone differently. If you are used to hiking and spending time at higher elevations you have a huge advantage over us "flat landers". The last time I had to pull the plane over to the fuel pumps in Leadville I thought I was going to need to go on O2 lol.

It is a big advantage, It's can be really hard on visitors . But Lake city Airport?! How was the take off

A NRB mask is not effective in the aircraft. Must have a relatively tight fitting mask. And dependent upon altitude, a pressure demand mask capable of a tight seal, after oxygen is delivered under pressure.

@@buckbuchanan5849 This is not a pressure demand mask. It is definitely a non-rebreather and the bag should be filled. Although it has somewhat of a tight seal it is NOT meant to be as tight as a Pressure demand mask.

Thanks!

The Cirrus with Factory O2 have a 77CUFT tank in the tail. Thanks for watching!

+HDaviator You can only use a the cannula up to 18,000' above that your must use the mask.

+Denny Crane Seeing as how Mt Everest is the highest point on earth where are you hiking that is at 14000 feet?

+Epica124 he's hiking on Mt. Imagination.

+Epica124 Mt Everest is 848x meters which is about 26000 ft.

Denny Crane I was trying to make a point which you total missed.

+Denny Crane It does effect you much more than you would think. Especially fine motor and problem solving. It also has lot to do with physical fitness and a persons physiological adaption to lower partial O2 pressure. Here is a good article www.ncbi.nlm.nih.gov/pmc/articles/PMC1114067/ and Here is a calculator that you can plug in altitudes and get the air pressure and how it will effect your body. www.altitude.org/air_pressure.php

+Ann Myers Correct, above 18,000' MSL you must be on an IFR flight plan.

+Pilot Winebrenner Class A airspace

+John Yyc Because airliners pressurize the cabin so that the air pressure inside is the equivalent of a much lower altitude.

+John Yyc A normal airliner is pressurized to a cabin altitude of 7,000 to 8,000 ft. So at 39,000 ft you are breathing the same pressure inside the cabin as you have standing on a mountain at 8,000'

so this plane is not pressurised then?

+John Yyc Correct, most small aircraft are not pressurized.

thkx for the info.

inhalation of the air in the cockpit isnt a danger, as smoke would be for a firefighter. Also, masks can indeed seal around a beard. In the oil field working around H2S there were masks that indeed sealed enough for having a beard.. some companies allowed it some did not...

92% Is not going to kill you though.

Crashing a plane is probably less dangerous than crashing a car. When a plane crashes, it usually just dumps in a field somewhere and doesn't kill anyone other than the pilot. A car, however, is usually traveling at 50+ mph around dozens of other cars. If the driver becomes incapacitated and loses control, he is likely to take someone out with him. So flying a plane alone, regardless of your health, is far less dangerous than driving a car alone. Furthermore, to fly a plane alone, you typically have to get medical clearance from an FAA appointed physician. No such medical clearance is required for driving. So you should really say "If you are not healthy, don't drive a car alone." Flying a plane alone is probably fine.

It is a prescription drug when used for thearapy, but for FAA use it is not. You can go to many FBOs and get your O2 filled, just like you can go get oxygen for a cutting torch filled without a prescription. (Although all three of those are "different" oxygen.

@@Caderic so you're not aware of the hazards of breathing in oxygen then?

@@PeterPete Oh yes, I used to be a paramedic, I am very aware, as is the FAA and FDA and the rest of the alphabet soup. The hazards of breathing oxygen is that people like you live. Without oxygen we die. As far as to much oxygen...yest that is a real thing and I am also aware of that. And regardless of weather I, personally am aware, YOU DO NOT HAVE TO HAVE A PRESCRIPTION FOR AVIATION OXYGEN. When you are hypoxic (which starts at about 10,000 ft.), the hasards of to much oxygen oar overshadowed by the fact that you don't have enough. Which in case you aren't following, when you don't have enough oxygen, that is the exact as to much.

@@Caderic i just find it amusing that oxygen is a drug and yet pilots can take it whenever they want! it's stupid!

@@PeterPete Your statements are becoming more ignorant. First, pilots are trained in the use of oxygen. Second, pilots are inherently levelheaded and intelligent (sans the outliers). By the way, caffeine is a drug. The likelihood of something happening from to much oxygen is extremely low (

Gold586 thats incorrect, its the same as they tell you on commercial flights when youre on the ground and they go through safety procedures, they say in case of a decompression and you get the mask on although the bag does not inflate oxygen is flowing
