That's one of the main design faults of the F-16A's. At least the Engineers alleviated the EPU activations due to main power loss, with the advent of the 10 KVA Standby generator on all C/D Models.
While the standby generator does add another power source, it does not eliminate EPU activations due to power loss...they can be pilot (or engine operator) induced. For all F-16s, even the C/D and E/F, with the engine turning and the EPU switch in NORM, if the pilot (or engine operator) places the MAIN PWR switch to BATT with the EPU safing pin pulled, the EPU will fire. The EPU will also fire if the MAIN PWR switch is placed to OFF, but is in the BATT position for approximately one second. |

loss of power on the Essential bus to be specific that comes from the #1 BPC which gives the ARMED signal to the Standby GCU. The standby GCU is what fires the EPU.......EPU control relay===to the EPU power lock relay...... Damn I miss the 16!!!!!

Since no one has replied to my post on the parent forum, I thought I would ask it here.
I was told that the Japanese F-2 used JP-8 for the EPU instead of sticking with the hydrazine in the normal F-16 designs. Any reason why they would move to a slower burning fuel? |

What are you looking for?

--Edit-- Added this MSDS stuff...
Quote:
The OSHA MSDS format has the following required categories that must be on every MSDS (per OSHA Form 174):
Section I. Manufacturer's Name and Contact Information
Section II. Hazardous Ingredients/Identity Information
Section III. Physical/Chemical Characteristics
Section IV. Fire and Explosion Hazard Data
Section V. Reactivity Data
Section VI. Health Hazard Data
Section VII. Precautions for Safe Handling and Use
Section VIII. Control Measures
The American National Standards Institute (ANSI) approved an alternative format and published a standard Z400.1-1993, "American National Standard for Hazardous Industrial Chemicals-Material Safety Data Sheets-Preparation."
The 16 sections of an MSDS that are prescribed by the ANSI standard are as follows:
Section 1. Chemical Product & Company Information
Section. 2. Composition/Information on Ingredients
Section. 3. Hazards Identification
Section. 4. First Aid Measures
Section. 5. Fire Fighting Measures
Section. 6. Accidental Release Measures
Section. 7. Handling and Storage
Section. 8. Exposure Controls/Personal Protection
Section. 9. Physical and Chemical Properties
Section. 10. Stability and Reactivity
Section. 11. Toxicological Information
Section. 12. Ecological Information
Section. 13. Disposal Considerations
Section. 14. Transport Information
Section. 15. Regulatory Information
Section. 16. Other Information
While this is a recommended format, it is important to note that at a minimum, the OSHA required categories must be addressed in the MSDS as these are legally enforceable (in the US).
MSDS's in ANSI format have a few distinct advantages over those prepared using the standard OSHA Form 174 format:
1. ANSI-format sheets have all of the information required on the OSHA 174 format sheets as well as additional useful information.
2. The information on an ANSI format sheet is arranged in a consistent format whereas OSHA has no format requirements, only content requirements.
3. ANSI format is likely to be consistent from country to country, possibly permitting one to use the same MSDS in different markets without modification (Hey, a standard! Imagine that).

I was exposed to H-70 and got all kinds of problems.
I am now attempting to get VA help. Do not mess around with this stuff. It is powerful and NASTY.
Anyone else out there get exposure? |

I have had cancer, short term memory loss, siezures, cluster migraines and a liver output that was out of wack for over 6 years.
H-70 is a nasty nasty fuel. Use me as an example of why it should be FEARED. My exposure was in the 80's and IT DOGS ME STILL TODAY.
Crew chiefs need to realize what COULD happen. It can mess your whole life up quite seriously.
I am now a desk engineer. I cannot fly anymore because I had the siezures. I cannot remember simple things like what I had for lunch yesterday.
FEAR THIS FUEL.
I have now to battle the VA to get help. That is also no fun.

Great info on the EPU... As an F-16 Fuel Sys Instructor, I'm always looking for new ways to explain it to the troops. (thanks Mark, Bix, IDcrewdog, etc.)
True... H-70 is 70% Hydrazine/30% water. Creates a chemical reaction to iridium. Spins a turbine to 75,000 RPM (as we say in Boston, wicked freakin' fast!). Powers an electric motor and a hydraulic motor (not sure which system, but I'd hope both to some extent (don't they bleed together a little?)). Exhaust is steam, ammonia, hydrogen and nitrogen at up to 1600 degress F.
Flase... If you smell it you are dead. Just smelling it is considered "overexposure"; more than is considered safe. Having been "exposed" many times, I'm living proof. I didn't enjoy the endless pricks (from the needles) to get my blood tested, but Hydrazine collects in the liver (and other organs) and doesn't ever go away. Other toxins (like benzyne in JP-4/5/  collect as well, but get excreted over time.
I've been a first responder to many crashes and seen the H-70 tank in different states, from still in the jet, to pieces.
If you are still interested in pics, I can get you some from the trainer we use in class. Sort of a full mock-up of the jet.
