  1. I think I found what you're looking for. The specific diagram I found is called "AC Generator and Control Panel" in a chapter about the unregulated AC system.


    I'm on a pretty slow internet connection this week, but if you send me a private message I can try helping you get a copy of this Lockheed manual.

  2. 521 is now located behind a fence in a secure area so there is no way to get a photo of it. All you can see is the vertical stab sticking up above the fence. There is also another herk trainer (fuselage only, no wings or empennage) parked in the same secure area.


    If you let me know where the other ones are parked I can try to drive by and snap a pic.

  3. I imagine whoever said that would argue that you have more cooling air with the bleeds closed but it wouldn't do anything for the oil circulating through the engine or gearbox.

  4. According to the paperwork I recieved from the VA, a 10% rating for tinnitus is a federal limit. In order to get more than 10% you need some other disability rating in addition to the tinnitus. A 10% rating for tinitus entitles you to your monthly check from the VA and free hearing aids and eye glasses.

    The tinitus claim has nothing to do with where or when you served. I just had to tell them that I've been working on the flightline for 10+ years, answered some questions, and sat in the hearing booth. They didn't care where I was stationed or where I've been deployed. This was in 2012.

  5. My USAF experience: 5 halon 1211 (BCF) fire extinguishers:1 on the flight deck (245 bulkhead) and 4 in the cargo compartment: one on aft 245 bulkhead, 2 on right side (aft of wing), and 1 forward of portside paratroop door.

    125 +/-50 psi

    All the herks I've seen have 4.

    Flight deck, back of 245, left wheel well, and right paratroop door.

  6. CAUTION: The underfloor heat switch must be off

    during engine starting and switching of

    loads from one generator to another.

    Failure to comply could result in a

    burned out generator control panel.

    Why GCP burn out can some body explain with logic

    I don't remember the exact reason, but I seem to remember that this is not an issue with the newer GCU.

  7. I recently saw a new E model at Kirtland AFB. It's parked in a field as a training device now. I wrote down 521, but I don't remember the rest of the tail number. Does anyone know where it came from or how long it's been at KAFB? Couldn't find it in the database.

  8. The -1 seems to imply that the brakes work better with high heat because the cooling times have been omitted and the requirement for runway available to exceed landing distance by 300' has been eliminated. Lowering the fuse plug temperatures doesn't make sense to me because a 130,000lb airplane has the same amount of energy to dissipate whether the brakes are made of steel or carbon. To answer the question, the brakes on our jet did better after a full stop landing, but still would not hold the plane static at takeoff power.

  9. I'll try to tie this in here since we're talking about carbon brakes:

    Does anyone have experience with the creep during high power settings? I flew with carbon brakes for the first time recently and the brakes were not able to hold the airplane at 970 degrees TIT. We were noticeably moving forward, the only time I've ever seen that before was on an icy runway. We know there is supposed to be an acceptable limit for creep, but who else has experienced this? Is there a fix in the works? On a real life max effort how in the world is your TOLD data supposed to be accurate if you're already moving down the runway before you can verify the power setting?

  10. You can contact the brown suiters (Lockheed contractors) at Kirtland AFB, they still run simulator classes and system refresher courses there. They have good training aids for all the special ops planes and you could rewrite some information for your specific planes.

  11. I think the type of diagrams you're looking for are for official use only and can't really be shared. Some civilian contractors who fly the herk might have that info though. There are tons of pictures and videos that could give you a pretty good idea what the back looks like and if you have questions more specific about certain parts I'm sure someone could help. Maybe you could find a static display or contact a nearby military unit and request a tour of an aircraft.

  12. No 4 propeller sometimes comes low oil warning light & automatically goes out.hydraulic level is available.check float switch,wiring is ok.change pump housing but action.please give suggestion.

    Check the wire connections at the engine firewall. We had one plane that had an intermittent prop low oil light because of a shorted wire on the QEC quick disconnects.

  13. It can also be somewhat uncomfortable to go from the loose and cozy flight suit to the OCPs because they have a regular waistband with a belt. But there are a lot more pen pockets for us engineers and that's what really counts.
