Why Do Fathers Experience Premature Graying?

[dlgoff]

Metropolitan State University of Denver is about the only small school with an Aviation and Aerospace Science program. It's closer to Denver than Golden.

No. The school is either in Golden or very near. I'll let you know when she replies to my email.

Sorry if you've already mentioned it, but what type of career does this degree and specialty lead to? Commercial airline pilot (kind of like a BS in Nursing helps a lot in getting to higher levels of RN positions)? Or some other aviation career? It seems like she is on a great trajectory (pun intended)!

Well, she's got her commercial license. see: https://www.physicsforums.com/threads/why-fathers-get-gray-hair.905235/post-6829241
But her flying club, I think, requires the degree. I'm a bit confused though.

 

[berkeman]

Well, she's got her commercial license.

But for single-engine ICE I think. Not for multi-engine commercial jets...

But her flying club, I think, requires the degree.

Oh, maybe to be a Flight Instructor...?

I think @Astronuc mentioned Flight Instructor and passed that on to her. I think that would be a good idea. She did mention that now she can get paid to fly folks to their destinations. So maybe she'll be doing that a lot?

It's been a while since I've posted in this thread. No gray hairs but proud to let you know how my daughter is doing now. From an email:

Things are going fine. The new semester starts this week so I’ll be going to class. Other than that, I’m finally finishing my tailwheel endorsement, will hopefully have that done this week.

Can never be too proud of her. :)

 

[berkeman]

What's a tailwheel endorsement? A slightly different aircraft configuration?

 

[dlgoff]

What's a tailwheel endorsement? A slightly different aircraft configuration?

From: https://en.wikipedia.org/wiki/Conventional_landing_gear
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail.
See the tailwheel on this image:

edit: an endorsement is an entry in her log book saying that she can fly tail wheel aircraft.

 

[Borek]

As far as I am aware handling of tailwheels is quite different from other types of aircraft, especially on the ground. For example during landing they are much more prone to tipping over. They have lower drag in the air though.



My understanding (and limited experience from MSFS) is that they are not difficult to fly, just a bit different.

 

[Filip Larsen]

For example during landing they are much more prone to tipping over.

You usually make three points landings for tail draggers to ensure you can pull back on the yoke while braking without risk of taking off again. Looks like that guy landed too fast and did not counter his wheel braking.

 

[pinball1970]

My feeling was that our comments should be geared towards Dlgoff avoiding getting more grey hairs ;)

 

[dlgoff]

I just got an email from my daughter. Here's one thing she mentioned:

I finally have my tailwheel endorsement.

edit: Here's what she said when asking what exactly was an endorsement:

...it is an endorsement stating that you’ve received and logged the required training by an appropriately-rated instructor and have been found competent to fly tailwheel airplanes.

 

[Borek]

Yes, but being just a Sunday MSFS flyer I didn't want to get into details and pretend I am in any way an expert

Don't worry - that will stop the plane just fine. In almost no space at all.

I thought I'd share some new photos from my daughter which adds a few more gray hairs. One good thing is she is training to become an instructor.

She probably has done a bunch of them. See this:

 

[berkeman]

Yikes, I'm guessing that beeping near the beginning is a stall warning? Woo-wee!

 

[Grelbr42]

Climbing with no helmet and hair just in a pony. Somebody thinks they are immortal.

A helmet would be a good gift for the next time there is some excuse. Falling rocks hurt. Falling on rocks hurts. The hair done up in some kind of bun stuck in the helmet would be a good thing. Hair in your eyes due to a puff of wind at the wrong moment can be a nasty surprise.

Yep. That's what that means.

I guess your are referring to the image in the first post:

She's been doing this for a long time. No worries. I think her flying aerobatics is more dangerous.

What's with the funny mustache things?

What's with the funny mustache things?

I'm not sure. When I first saw that, I thought it might be oxygen. But I'll have to ask her.

@BillTre
edit: I just got an email from her about something else and I asked her about this. I'll let you know when she replies.

 

[dlgoff]

What's with the funny mustache things?

I just got this reply saying:

We were wearing oxygen, as we went to a high enough altitude that is was required. They look goofy because those are just ones that go into your nose and they have sticky pieces that keep them on your face.

 

[berkeman]

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.

 

[dlgoff]

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

 

[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.

[jrmichler]

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.

 

[berkeman]

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?

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.

 

[berkeman]

I did some internet searching, and came away with the impression that that concentration is typical for that altitude.

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).

 

[pinball1970]

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

That's pretty cool.

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.
