Why Do Fathers Experience Premature Graying?

[dlgoff]

Oh yeah, now that I look closer I see where the clear O2 tubes go in the ends of the mustache things:

So I guess the O2 tanks are somewhere behind the seats?

edit: I just asked her where the tanks might be.

 

[berkeman]

Yeah, must be. Those are low-flow nasal cannulas, probably around 3 liters per minute. That's not much extra O2, but apparently enough for the regs.

So that suggests a good birthday present that you can get her -- a pulse oximeter so she can check her O2sat level every once in a while on the flight...

I asked her about where the tanks might be and this is what she said:

... I believe that airplane had an on-board oxygen system vs portable tanks.

@berkeman
I was just thinking that you wouldn't want portable tanks flying around should you have to make a hard landing.

I did a brief search, and it looks like there are multiple ways that the O2 can be stored in aircraft. I'm sure that wherever any O2 canisters are stored, they are well-secured with hopefully some impact padding around them.

Both I and my passenger measured 78% on a pulse oximeter at 12,000 feet one day about a year ago. The FAA requires oxygen if over 12,500 feet for more than 30 minutes, and at all times over 14,000 feet for general aviation. That's a minimum requirement, they suggest oxygen when over 10,000 feet. Part 135 (commercial) operations have more stringent requirements.

Wow, that's crazy low if you were my patient at sea level (like "load and go" low). Is that typical for no-O2 at that altitude? Have you taken a similar reading while on 3L/min. of O2 via nasal cannula?

And I thought it was a perfect game of bowling!

I did some internet searching, and came away with the impression that that concentration is typical for that altitude. Apparently age does not affect blood oxygen vs altitude, which was good because we were 70 and 71 respectively. The airplane was a Cessna 152, so no oxygen system.

It's difficult to measure one's own performance, but I was able to correctly maintain climb attitude, airspeed, situational awareness, and panel scan the entire time.

Yeah, it looks like that is so. I found this just now:

Does altitude affect the pulse ox? Should I use it at altitude?
Yes, dramatically so. At 5,000 feet, if you don’t breathe any faster than normal, your O2 saturation will be about 90%. If you take 5 extra breaths per minute, you can increase this to 95%.

At the extremes of altitude, the changes are even more pronounced. At 10,000 feet, if you breathe at a normal rate, your O2 saturation would be about 80%. At the summit of Mt. Everest, if you breathed at your normal rate, life would not be sustainable. In fact, you would need to breathe twice as fast as normal, and twice as deep as normal, just for your oxygen saturation to be 35%. And that’s if you’re standing still, not expending energy! This is why only 3% of the summits of Mt. Everest are done without oxygen [2].

It's crazy that your O2sat can be that low and you don't exhibit an Altered Level of Consciouness (ALOC).

300 hours is 12.5 days, twice round the earth at a leisurely 167 mph..

That's pretty cool.

I just found out that my daughter will be taking her Certified Flight Instructor testing in June.

I just found out that my daughter will be taking her Certified Flight Instructor testing in June.

I just got this email from my daughter (no gray hairs because of this):
"Hi dad, just wanted to let you know that I passed my check-ride this morning and am officially a CFI (certified flight instructor.) I’ll be interviewing with the chief pilot in a couple of weeks to officially start on as an instructor at Aspen. Here are some pictures:"

 

[Vanadium 50]

Good for her!

Did anyone catch the typo in that flyer?
I just reported it to the phone No. on the back cover.

Cheers,

I'm not seeing it. Which page?

 

[Vanadium 50]

There is presently one T-38 (supersonic military training jet) on sale for the low low price of $800K, although it probably will be closer to a million after the paint job and filling the tank with fuel. And it's a two-seater! Think of the fun she could have flying her dad hither and yon.

Inverted.

Been a while since I posted in this thread. Here are three photos of my daughter and all the folks in her department where they are all Certified Flight Instructors (CFI) now:

Also, she has began teaching now. I'm so proud of her.

She always looks exceedingly happy.

No new gray hairs. Just wanted to give an update on my daughter's flying, etc.

I emailed my daughter to see how she was doing and this is part of her reply:

...I have about 5 female students now. Classes for the fall semester start up in a week and a half so I’ll be busy with it all.

 

[Vanadium 50]

While looking through the government surplus list. I see a few AV-8B Harriers. If the T-38 Talon is too impractical, this might be an alternative: it's VTOL, so it might just fit in your garage.

Alas. I only saw the single-seat version.

So don't say I'm not looking out for you!

Fixed that for you.

 

[Vanadium 50]

I was actually surprised to see military aircraft on the surplus list. I am kind of imagining someone calling and saying "we'll take three boxes of pens, the big file cabinet, and a half dozen Tomcats please".

It's been a while since posting in this thread. Here is what my daughter mentioned in an email: "I do have a little over 500 (flying) hours now. Slowly but surely building them up."

 

[Filip Larsen]

I understand as a full time GA CFI you can expect upwards of 400-500 flight hours per year. I'm not sure, but I would think that instructors get to log the flight hours with student pilots (since the CFI is pilot in command), but maybe not once the student has gone solo, and surely not if the instructor are doing checkout rides for other pilots.

Sounds right. But I'll have to ask her about it.

LOL, looks like a comms radio to me (with display), but good question...

 

[Filip Larsen]

I guess that dashboard requires good eyesight and long arms for full usage. Or, alternatively, a good co-pilot.
