    Guard/Non-prior, I feel my dates have been a lot quicker than everyone so far:

    Interview: September 2017

    Hired: September 2017

    MEPS: November 2017 

    FC1: November 2017

    Waiting on OTS dates now. Is it typical that my package gets sent after my FC1 is cleared or is the package sent without the FC1 information? Also, I assume that if we failed any part of the FC1, we'd know about it within a few days of the physical rather than months after? Lastly, I was a couple pounds over for the FC1, will the AGB see that as an issue? Obviously I'll be the correct weight before OTS and was for MEPS, but Thanksgiving happened.

    I was told the package sits at NGB awaiting an approved FC1. Yes, you should have been told if there was any issues/waivers needed when you were at Wright-Patt. A couple pounds over the max weight for the T-6? That weight is around 245 or something... Don't quote me, but just figure that out. If you're over that weight, I don't really know what happens.

    Also, that is pretty quick for FC1, so hopefully NGB approval will be pretty quick for you too. Congrats!

    My G-dad flew the RF-4C at Shaw, though he retired in '70.  Funny - he always talked about how much power the F4 had.. I guess coming from the planes he flew from '43 to '70, they did.

    I've heard F-4 pilots describe it as "the military's science project to prove that, if you strap big enough engines on anything, it will fly." 

  3. I don't have platform specific numbers with me. I know from looking at charts of oxygen analysis being done on some test jet aircraft (OBOGS) that the numbers on the ground are usually max performance (95-100%). For some aircraft, there is an OBOGS source change that happens after Weight Off Wheels that immediately shows a drastic decrease in O2% by vol, then increases back up to about 60-80%. The F-16 OBOGS O2 concentration to the face is very similar to the F-15 LOX, except it has a steeper increase at low atitudes.

    A lot of pilots let their mask hang until they absolutely have to put it on, but then they are getting that mass influx of oxygen to the lungs. When it is absorbed by the blood stream, and the pilot is still breathing a very high percentage of oxygen, the alveoli start to collapse since there is not a high enough concentration of Nitrogen to retain the shape (or so the theory goes).

    Luckily, with all of the OBOGS issues, they are implementing sensors in a lot of places in a lot of aircraft and this theory will be proven or disproven soon.

     

    As for the T-6 IP hypoxia issues, I would have to look at the debrief from the flights/ground events. I don't know if I buy off on lack of SA because a lot of the bad cases of hypoxia end up being "Oh, I remember being cleared to land and I didn't really feel good. I remember taxiing off the runway, but don't remember actually landing the plane." If that's the case, then no amount of (lost) SA is going to help you keep 69 seconds of flight time that would have otherwise been lost due to oxygen deprivation. Personally, I'd look for 1 or 2 aircraft that have the most amount of hypoxic events associated with them and start digging deeper. In addition, it would be a good idea to do hose leak check, mask fit check, mask leak check, concentrator and regulator replacements, check for water in the system (obviously), etc for all aircrew/aircraft that had an incident. I'm sure whichever team has been tasked to deal with this issue is already knocking out that easy stuff.

    Doesn't the O2 bottle deliver 100% O2 though? So if it truly were hyperoxia that would be exactly the wrong thing to do vs. say descend and drop the mask. If they already have a new boldface directing crews to the O2 bottle I would assume that they ruled out hyperoxia and it's either foreign contaminants in the OBOGS, some form of CO/CO2 poisoning, or the OBOGS is malfunctioning and not supplying sufficient O2 quantities leading to hypoxia. 

    Yeah, for sure the bottle is assumed to be 100% O2. This is debatable when OBOGS is not secured on certain platforms, due to the nature of the two way switching valve, but that's a whole other argument. Anyway, the hyperoxia focus is not stating that the EPs are an issue, just that the initial oxygen that aircrew is exposed to is not helping at all. Oxygen concentrations should start low at low altitudes, and increase from there until it gets to 100% concentration at higher altitudes. This has successfully been done on LOX jets in the past. The fact that OBOGS jets now are going from 95-100% O2, then back down to around 60-80%, then once again increasing to 100% could be hurting more than just a non-linear increase in concentration based on altitude, and could explain why they (OBOGS aircraft) have far more physio events.

    That is interesting, but also curious as to why it seems it's mostly Vance (plus one at Pensacola recently?)

    Yeah, the hyperoxia theory doesn't quite explain the specific cases of aircraft at one particular base being bad. Hate to think the maintainers are catching all the blame, but no doubt they are being scrutinized (who worked on what airplane and when). The fact that the IPs are the ones getting hypoxic is something that I'm sure the AF team of engineers or technical experts will start to focus on.

  5. The only time I'm a doctor is when I'm talking to a hot chick at a bar... But, from what I recall the actual doctor saying, the hyperoxia (oxygen poisoning) theory explains that breathing (in this case) 95% oxygen on the ground when usually we'd be breathing ~21% might be a bad thing. Our OBOGS-equipped platforms we fly are able to deliver 95-100% O2 on the ground, and in military flight, the mask is supposed to be on during checks/taxi. So on the ground, this leads to "absorption atelectasis". (From Wikipedia) Since oxygen is exchanged at the alveoli-capillary membrane, nitrogen is a major component for the alveoli's state of inflation. If a large volume of nitrogen in the lungs is replaced with oxygen, the oxygen may subsequently be absorbed into the blood, reducing the volume of the alveoli, resulting in a form of alveolar collapse known as absorption atelectasis.

    In flight, this leads to acceleration atelectasis and pulling G's can cause the base of the lung to collapse. So basically, drastically changing the composition of your alveoli on the ground, then going up and being exposed to O2 concentrations that vary between 60-80% during flights where you do multiple altitude changes is causing hypoxia (that's the theory at least).

    Now take a jet like the F-15 where LOX and a diluter-demand regulator is used... At 10k' altitude, 25-50% O2 (by volume). At 20k' altitude, 40-65% O2. Finally, around 28-30k' altitude, the regulator stops diluting the incoming oxygen from the LOX bottle and 100% O2 is delivered for those altitudes and higher. LOX jets historically have a MUCH lower (reported) percentage of hypoxia events per flight hour.

    Anyways, none of this is my research, but I just thought those basics were very interesting especially given the OBOGS issues in the T-6 (and across multiple other platforms as well).

    That doesn't make sense. Saw the fcif today and it came with specific direction that old procedure of gangloading was ineffective due to potential contaminants/toxins in the OBOGS. The emergency O2 it specifies is the only guaranteed source of pure 100% O2 hence the new boldface to pull green ring for hypoxia rather than gangloading. 

    Not an expert, but thought the T-6 OBOGS was capable of producing 100% (or close to it) O2 on the ground? (not debating the boldface)

  7. Stay positive... UPT is going to be a lot more challenging than two interviews. Thank the unit for letting you visit (which you should do before the interview) and giving you an interview, and then ask for feedback. If they don't want to give feedback, don't push the issue. Bring booze, don't be a douche, and everything else that's been said 69 million times before on the forums.

    Stay the course and good luck.

    Has anyone recently (in the last few months) had their package sent up to NGB and it just stall there? My recruiter says they're trying to find out why it's been there for 12 weeks. I'm just curious if anyone else has had a problem with this or if it's just my shitty luck.

    I've heard non-priors, not age critical, no waivers required taking 4-5 months. A few people I know had to wait 6 months between swearing in and FCI.

    Don't talk about gun regulation in a thread about guns?  I don't follow your logic.

    Ha, you got triggered by a picture of a gun.

    Anyway, since you've already referenced the tragic shooting in Texas (and even commented on that thread), I think he's suggesting the other thread might be a more directed place to voice your opinion. Hell, you can even open up a new thread.. God knows those with enough foresight already have popcorn in hand waiting for your next post, wherever it falls.

    How did they know about you not going to a follow up appointment and your anti-biotics?

    Dad was active duty for 20+ years. They knew everything about me medically. They pulled up a screen and said "looks like this was in your medical record" to which I replied "I don't remember that being a part of my history. I'm not necessarily denying it since I just go to the doctor when I'm sick, which is extremely rare, but I just don't remember that ever coming up." So that was written down in the notes and when I got to the final doc he looked into all the notes the nurse practitioner made 4+ years ago, said something to the effect of "oh they must've just said they never did a follow up appointment after you went in the first time for being sick", then basically scratched it out and said "no big deal" and off I went. I honestly had nothing to hide, but I didn't want something in my medical records that wasn't completely accurate. I have no problem proving I'm healthy with no previous health issues. I rarely get sick, so when something like that comes up I just want to make sure it's in my files correctly.

  11. We're trying to rationalize the response to an inconceivable evil. The fact that this evil committed the deadliest mass shooting in the US without ANY indicator(s) / motive (that we know of as of today) goes far beyond any political gun debate, and that's why it's driving everyone absolutely fucking crazy.

  12. Fuck that, I'll watch hockey. Those guys stand for the national anthem and until recently most of them were Canadian. Plus, this way I still get to watch paid professionals get decleated (de-skated?) and square off like boxers from the early 1900s.

    Define it and give solutions to the problem.  I'm betting it sounds like a plank of the democratic/socialist parties.  For extra points don't use the words "social justice"

     

    Or "Institutional oppression"... Impossible to disprove, definitely exists to some extent (which can be blown out of proportion because you can't disprove it), and the added bonus of being called fascist if you question its reach and prefer to take an approach based on individual complaints rather than saying that (1) everyone in one group is oppressed and (2) everyone who isn't oppressed is basically aiding the oppressors and should be punished. Collectivism 101

    You don't have to agree with what Trump said to question the kneeling.

    You all should go look at what Ha Ha Clinton-Dix said as well as Dak Prescott. Two outstanding examples of guys who appreciate the position they are in.

    Can't find it. What did they say?

    HaHa Clinton-Dix posted words from the "NFL League Rulebook" that basically gave guidelines for the anthem and stated that those who do not follow the guidelines could face discipline. He has also worn cleats with the names of four slain officers to honor them during a preseason game. http://dailycaller.com/2017/09/25/green-bay-packers-star-takes-subtle-shot-at-national-anthem-protesters/

    “I understand what’s going on in this world,” the Green Bay Packers third-year safety said. “But cops have to go home at the end of the day. They have a family. They have to go home, too.

    “Growing up where I’m from, some people are afraid of cops. They don’t really like cops. And what a lot of people don’t realize is, they’re really not the bad guys. They’re really on our side, they’re really trying to help us out. And sometimes, we don’t understand that.” https://www.sbnation.com/2017/8/22/16186514/ha-ha-clinton-dix-honor-four-fallen-police-officers-cleats

    You must be mistaken. California gun laws are strict, like in Chicago, so it's pretty much impossible for criminals to get their hands on one.

     

    Robber's Mom: "Stabbing somebody that many times, it doesn't take that many stab wounds to get somebody to succumb to you."

    Wow, it's a mystery as to why your son didn't grow up to be a model citizen. Also, she seems to be an expert on submission through stabbing. How many times do you stab a man pointing a gun in another person's face before he is neutralized? Do you stab 5 times, then give the robber a chance to (1) run or (2) reach for their weapon and possibly shoot/stab you back in the interest of fair fighting? Is the initial number of stabs based on height, weight, strength, gender, and age of the criminal to be neutralized? Do you get to subtract the stabs received by the good Samaritan (1 to the neck in this case) from the initial number based on the variables? Is there a multiplier based on stab location (the neck is worse than the foot I would think)? The math might get tricky. A little advice from my old man (I'm sure, being a veteran, he didn't come up with it): Don't EVER point a gun at something you don't intent to shoot, and be damn sure you've considered all of the consequences of such a decision before acting.

    Well, we tanked our season in style by laying down for the second half and letting UCLA pull off an epic come back. I for one support the A&M regent calling for Sumlin's firing. He should have been fired in the locker room.

    We ran all over them the entire first half, then with a lead we threw the ball the entire fourth quarter with a true freshman quarterback. Madness.

    That was a surprising loss for A&M. On the plus side, you didn't lose your starting quarterback for the entire season.

     

    Well, at least for both teams I can't imagine they'll play worse games than that anytime soon. I honestly think those are the worst performances out of those two teams I've ever seen. Bama vs. FSU seemed like a battle of who could suck more when awesome field position was given to the offense.... FSU "won"

    Here were my AFOQT scores:

    • Pilot: 75
    • Navigator: 68
    • Acad Aptitude: 46
    • Verbal: 34
    • Quantitative: 60

    As for Flight hours, I had 22.  To get to 80, I'd need over 200 hours.  I see a lot of people ask your first question.  Why does that matter?  Is it a measurement of the score or something?

    I definitely say study your ass off and retake the AFOQT. No one will be able to tell you exactly how much your PCSM will rise, but raising your AFOQT pilot will definitely have a positive impact on your PCSM. Plus, you already seem to be leaning heavily towards a retake.

    I don't know how true this is today, but I've read that a few people were sent to IFS/IFT (even when they had a PPL) because they did NOT have an 80 PCSM with their hours. The category that shows the greatest percentage of successful UPT completion in the most recent PCSM study is 79-99. Does that mean that someone with a 79 PCSM has the exact same chance to complete UPT as someone with a 99 PCSM? No, I don't personally think so... but there isn't a more recent study to back up my claim.

    Finally, after you bump up your AFOQT, I would definitely finish your PPL. The PPL is a major box to check, plus the extra hours will push you into higher PCSM columns, so that's 2 very big reasons to keep flying at your stage. If your AFOQT retake makes it so that you can break 80/90 at 101-200 hours instead of 201+ hours, you've already halved the amount of time/money you need to be competitive.
