  1. A heavy can experience a compressor stall at high power settings during the beginning of the takeoff roll if crosswinds are strong enough. This is due to the fuselage disturbing the airflow to the downwind engines. Specifically, Boeing 707 type airframes have a recommendation for max crosswind with a static takeoff for this very reason. Above about 30 kias, however, there is no way a crosswind could affect the engines.

    One other thing about some older engines on the heavies is as compressor blades wear then the stall margin decreases. The F108 on the 135 has some old, high time engines that can under certain crosswind conditions on taxi and early in the takeoff roll, stall.

    On my earlier point an A-10 had a disk let go in the not too distant past. There's even a case out there on a ground run where an American 767 I think threw a disk that went clear through the fuselage into the other engine. I know everyone remembers Souix City. Improper forging left an inclusion that caused it to fail. Thats why disks have eddy current/ultrasonic inspections and hard life limits

  2. Bolterking,

    How likely was it that the crew was intentionally dumping fuel versus leaking fuel? With as little time as they apparently had then they were sure on top of things either way. If a part of the engine liberated (I'm referring to something heavy like a disk as opposed to blade(s) which I would suspect would stay contained) then it could easily puncture a tank and maybe account for some witnesses (assuming they're right) saying they saw fire prior to impact.

  3. Agree, dialing in a little suit pressure can help with those "minor" issues I expect everyone had from time to time.....football knee for me.

    Kevin Henry is a great pilot and had lots of experience in the plane. But as the saying goes, sh*t happens. The fact he survived in the end proves the old adage "it's better to be lucky than good."

    A DCS hit like that to the CNS is rare but obviously can happen.

    The modification is the answer.

    Cheers,

    Saw the same article. I'm guessing there's weight penalty incurred for the MOD though it's obviously needed. Interesting to see how and if this plays into the manned vs unmanned argument.

  4. In 'highly unusual' move, Marines asked to disarm before Leon Panetta speech.

    Sorry Leon but it's a war zone. If you're afraid of getting hurt then stay home and save the taxpayers all the money spent for you Afghan/World tour.

    On the other hand the lengthy judical process for the lunatic SSG will mean it will be years before justice is served and Locals will just get more and more pissed. In WW2 he would have been tied to a post about a month from now and shot.

    Check yourself dumbass. The only fixed wing time I had was what I got going through the flight screening program at Hondo. That was about 15 hours. I went direct from Hondo to Ft Rucker. The first time I saw a Tweet was at Vance.

    Ok Yeager; ###### you and the horse you ride on.

    Wow,

    Wonder what the average blood alcohol content is for posters on Christmas Day? :jd:

    Not that I would EVER drink and post :thumbsup:

  6. I'm not looking for a uniform item but I am looking for a black A-2 style with Thinsulate in the lining. I've found jackets with the Thinsulate lining are pretty warm without the bulk which is important in some smaller civilian cockpits. I've owned a fleece lined leather jacket in the past and I found it restricted mobility.

    I've seen the LL Bean Thinsulate lined Flying Tiger Jacket but I don't like the way the back is sewn in two pieces whereas US Wings and the like seem to have one piece backs and look better in general though I don't have any idea what kind of insulation they use if any.

    Opinions?

  7. Right or wrong, smart or stupid.. categorize it however you'd like.

    In 4 days here at my new location, I've heard several good dudes/dudettes, both O and E, say they'll pull chocks ASAP if this new retirement plan gets put in place with no grandfathering.

    If I were still AD, I'd be seriously considering it, too.

    I'm sure Panetta was thinking the same thing when he made his speech. Regardless of what actually comes to pass the echelons above reality have to know that people will bail if they perceive the current system has become essentially use or lose.

  8. Frequent lurker here but I'm very familiar with the type of plane he was flying. The Mooney M20E (and all vintage Mooneys for that matter) are subject to tailplane stalls under icing conditions with flap deployment. Two separate commercial pilots who went missed before him reported light icing, which may mean something different to a much faster commercial aircraft than it does to a light fixed-wing. Preliminary report also detail a near-vertical impact, which suggests icing over other possible factors such as a forced landing or spatial-disorientation

    Coming up on 2 years this winter but I lost an old H.S. classmate with his 2 teenage daughters on an IFR approach under (at least apparently similar conditions). He was flying a Bonanza and he hit at steep angle. Based on where he was on the approach I would bet he was configuring the A/C for landing and I've wondered if he had iced up and the flaps coming down precipitated a loss of control. Anyone know if a (straight tail)Bonanza has the same issues as the Mooney?

  9. Anybody hear a plan for the Reserve Component? A few years ago they talked about a reduction from age 60 to draw the annuity base on deployed time. Looks like they'll keep leaning on the RC forces all right for now due to cost savings but flat out screw them in the end when it comes time to pay up on retirement.

  10. This guy was starring in Middle Eastern porn? Amazing we didn't find him sooner...

    Now that's funny......Well they use the drug trade to help fund Al Quaeda/Taliban why not make porn to supplement their income? Dirk Kashmeri former pornstar. Too bad he didn't realize his last role was in a snuff film

  11. Yeah, the tricky part is if I'm in the position where I have to show the letter, then why is there one in the breech?... Dicey at best.

    OR

    Or, base/cc's could man up and start allowing ccw on base. Crazy I know. I'd even be game for some caveats:

    -a confidential program (don't talk about fight club)

    -SNCO's and above legally ccw certified by the state (cc nominated)

    -zero drinking wg/cc policy when carrying

    But at the end of the day, it would take a human wave of aq rushing the gate before a base/cc allows anyone other than sp's carry on base. Really sad. That's all I've got: I have to go get my pt test monitored by some fat civ.

    ETA: really I'm going to not take your advice lest the next reply quote the oath, constitution, core values, reflective belt AFI, club membership, etc...

    Very well said.

    I love all the cheesy "Active Shooter Powerpoints" out there. Maybe if I print them all out and stuff them down my shirt it'll stop a .22. Most Base Commanders, I'm talking all service's here, care more about their careers. Until someone like the commander of Ft Hood at the time of the shootings is put on the hot seat for leaving the troops defenseless until a DOD civilian cop showed up, then they will continue the politically correct status quo.

  12. Llyas Kashmiri

    He was a heavy hitter in S Waziristan. He seems to be the facilitator between UBL and field jihadis. There was no love lost between him and Pakistan either. Whatever, props to those who bagged him and tagged him. :salut::beer:

    Hopefully there will be someone left for me to kill.

    EDIT: linky

    Maybe the Intel haul from Bin Laden's (former) crib is starting to bear fruit. Death truly comes from above.... :M16a2:

  13. Already thought of and relatively cheap to install - Nitrous Oxide. It's 33% oxygen as opposed to the normal 21% of the atmosphere. So when nitrous is injected, more fuel can be burnt than normal. Like a chemical turbo.

    I would rather save Nitrous for the dentist :rock: Knew a few guys back in my youth who loved to make cars go fast with the stuff. I'm the first to admit a lot of stuff is good in theory but is it practical in the real world is a whole new question.

  14. Every airframe seems to have their own way to say the same thing.

    MSOGS on the B-1 is the Molecular Sieve Oxygen Generation System. It sucks bleed air through a zeolyte bed which soaks up much of the Nitrogen. The gas that comes out is around 80-90% O2.

    OBOGS is just Onboard Oxygen Generation System. Don't know if the chemistry behind the system in other jets is different.

    Totally different slant for the science nerds..

    Anybody try to use a similar system to up the peformance/mileage of an internal combustion engine?

    Just thinking out loud

  15. Not sure if this is related

    From Reuters 22APRIL

    PESHAWAR, Pakistan | Fri Apr 22, 2011 9:43am EDT

    PESHAWAR, Pakistan (Reuters) - Two U.S. pilotless aircraft fired four missiles into a house in Pakistan's North Waziristan region on the Afghan border on Friday killing 25 militants, Pakistani intelligence officials said.

    The strike came two days after a visit to Islamabad by Admiral Mike Mullen, the top U.S. military official, in which he expressed concern over links between Pakistani security agents and militants attacking U.S.-led forces across the border in Afghanistan.

    The drone strike happened in Mir Ali town, about 35 km (20 miles) east of the region's main town of Miranshah.

    A Pakistani intelligence official in the region who declined to be identified said the house was being used as a militant hideout.

    "They have surrounded the area and are not allowing anybody to go there," the intelligence official said, referring to militants.

    Twenty-five bodies had been recovered from the rubble and three women were among those killed, he said.

    Another official said some foreign militants were among the dead but their numbers and nationalities could not confirmed.

    North Waziristan is a known sanctuary for al Qaeda and Taliban militants.

    The United States has been using drone attacks to target militants over the past few years in Pakistan's lawless ethnic Pashtun border areas.

    The attacks are a source of concern for the Pakistani government, which says civilian casualties stoke public anger and bolster support for militancy.

    During Mullen's visit, a U.S. official said the United States would not stop the drone attacks in Pakistan, despite Pakistani objections.

    Earlier, militants attacked a security post in the northwestern town of Dir killing 10 soldiers, security officials in the region said.

    About 30 soldiers were manning the post when militants attacked on Thursday, they said. Fighting went on for several hours.

    Security forces have been battling Pakistani Taliban militants in several parts of the northwest over recent years. The militants want to destabilize

    the U.S. ally and impose harsh Islamic rule.

    In 2009, the military cleared militants from Dir and the neighboring Swat Valley in a successful offensive.

  16. 1)DLA = DELAY

    2)PMA (reverse engineered by other than the OEM) parts forced upon us. Way more trouble than they are worth.

    3)LEAN/Just In Time concepts are fine for a manufacturing operation but totally jacked for a maintenance operation.

    4)DLA = DELAY

    Video was spot on

  17. Been a while since I've been on. Very busy...Who knew, what knew? all questions after the fact. We all do things in the air AND ground that CAN get us killed. Usually we get away with it. Is it worth the risk. Not usually in an Airshow. Learn the lesson and try to remember ALL the kids lost in A-stan on a day to day basis. Most of them weren't practicing for an airshow at the time.

    Thanks

  18. I truly wonder if the community will tear itself apart.

    I wonder what will happen when large numbers of dudes/dudettes get to the end of their commitment. For folks in the business;

    Are the claims of high job satisfaction true?

    What is the divorce rate?

    What is the DUI rate?

    What is the retention rate?

    I am a simple man and it would seem to me the answer is NOT to train more dudes...NOT to create UAV only pilots who lack SA. The answer has to be technology. We need to develop systems that allow one pilot to fly multiple systems and only intervene when completely necessary. We need to develop sensors that don't simply stare at one spot or are limited to a soda-straw view of the battlespace. When we can open our aperture and have one person controlling 4-8-12 RPAs with each RPA have a field of view and field of regard that covers many miles in a single look, then we will have arrived at something we can sustain.

    Oh...and I am completely in favor of putting GCS' in move favorable places like Fl, Co, Ca, and Hi.

    Didn't get all relevant quotes above but I think you'll get the idea.

    As my signature block states " This is a serious misallocation of valuable military resources" Frequently true in the military as we're all aware. However the purpose of the military is to deter war if possible, win if necessary. Anything that we as members of the military as far as job satisfaction get above that is gravy. I've gotten a lot of taskings and duty stations (we all have I'm sure) that were not desirable and I've been in New Mexico and Arizona in my military career so I can see the downside to those postings but I'll definitely say they are better than Iraq (where I've been) or Afghanistan (where I'll probably end up). Nobody said we had to like it.

    Whether we like it or not we adapt to fight the war at hand with the best tools we have available (and no I'm not trying to sound like Rumsfeld) That right now means UAVs. Many many years ago General Billy Mitchell tried to tell the establishment that Air Power would become the dominant military force over Sea Power. At the time no one wanted to hear it. Reality is reality.

    As far as technological advancements, UAV capabilities along with their command and control will evolve beyond what we can imagine in 10 or 20 years after most if not all of us reading this have retired. But it won't happen quickly.

    I do hope you UPT grads eventually return to the cockpit either in the military or civilian world. Right now we have a war to fight.

  19. As someone who could hear the buzz of the UAV high above late at night while manning a checkpoint, I do remember the bad guys made themselves scarce and fewer things were left to go boom the next day. I've even talked to "associates" of some less than savory characters who were well aware of the the death that can come from above and they spent as least as much time avoiding being spotted by the UAVs as going out and making trouble.

    I do fly on the civ side and love the air as much as anyone but I assure you seeing a Dad able to come home and hug his son after a year in the desert because a UAV kept the bad guy's from putting out an IED to kill him makes it all worthwhile.

    I think the UAV will be to the GWOT what the helicopter was to Vietnam.

    Thanks for watching over them. :beer:
