Last time I was down that way, they were working to rid the area of the suicide lanes.

Well, unfortunately, they are still going strong............I was almost wiped out a couple of times there!

Apparently signal lights are an option too!!!

Center of gravity limits are based on the chord of the wing, not fuselage length. All fuselage length does is add more stations but the end result of the computations will be the same and so will the takeoff and landing CG limits at corresponding gross weights. The Leading Edge of MAC (LEMAC) will be different but actual center of gravity is based on where it lies on the Mean Chord of the Wing (MAC.) US manufacturers use a point at or near the nose of the wing for weight and balance computations but they could use any point. British manufacturers use the center of the MAC as the reference point. It\'s been decades since I\'ve done a weight and balance on a C-130, but wasn\'t the reference point 30 inches forward of the nose?

The wing on any airplane (rotors on a helicopter) are the only part that actually \"flies\" (produces lift) and the balance point is on it. The tail exerts a downward moment to hold the nose up and does not produce lift. For the CG limits to change, the chord of the wing would have to be changed. The forward limit is the point at which the wing can not be rotated enough to produce lift or control forces will be exceeded while the aft limit is the point at which the wing will become unstable. CG also plays a part in aircraft controlability after the loss of the critical engine.

Yes, the RDL on the stubby is 30" fwd of the nose and on the stretch is 130".

And when referring to Mean Aerodynamic chord, the actual 15-30 % envelope is very small in relation to the overall size of the wing.

Welcome Titus;

I'm fairly new as well. I just finished my 130J course in LR in October, difference is, I joined the Canadian Air Force in 1986!!

I did enjoy my time there, although I don't miss the suicide traffic lanes!

Just a few questions. The internal Benson tanks held approx 11,000 pounds? (WC-130H) How many gallons? Also why "Benson", was that the builder? Next, station 245 was measured from where? I seem to remember that it was somewhere in front of the nose. What station were the paratroop doors at? Last, any idea how much hyd fluid was in the utility system at any one time. In motion, not in the resevoir.

Thanks

Good evening;

Everything on the C-130 is measured from the Reference Datum Line (RDL)

On the stubby aircraft the RDL is 30" forward of the nose and on the -30,

it is 130".

As for the para doors, it was mentioned by another poster that the ramp hinge is FS 737 on the stubby. For the -30 the hinge is at LS 1017.

So the end of the door on a stubby is approx FS 737, on the -30 it is LS 937.

The quick conversion between the stub and stretch is as follows.

Between FS 30 and FS 245, add 100" to convert to LS.

Between FS 245 and FS 737, add 200" to convert to LS.

Between FS 737 and FS 1202, add 280" to convert to LS.

Hope I wasn't too confusing there!

Have a good one.

If this image is from the ditching section, could the numbers refer to the order of preference for exiting the aircraft?

Mike

The figure above is titled "Emergency Entrances" Fig 3-2 exits are numbered

The Emergency "Air and Ground Exits" Fig 3-8

and "Emergency Exits-Water" Fig 3-10

are referred to as Fwd, Centre and Aft escape hatches and side emergency exits.

I bet that if the whole page was printed, there is a list that goes along with that drawing that says, 1= Rear overhead escape hatch 2= Center overhead escape hatch 3=Cargo compartment escape hatch 4= Flight deck overhead escape hatch, this looks like a page out of the IPB

Bob:

You are absolutely correct, however, the ditching fig that I had mentioned refers to them not as #'s but in the traditional format that we are all accustomed to.

As does the Ditching checklist.

See c-130J-1, Fig 3-2, Page 3-241; it identifies Aft #1, Center #2, RH Emer Exit #3 and Fwd #1. I tried to attach the Pic but couldn't figure it out.

I think that the numbering of the hatches was nothing more than convenience on that figure. Have a look at fig 3-8, all the hatches are identified as we all refer to them. Center overhead, rear overhead etc.

Any egress briefing that we take part in, we don't refer to the overhead hatches for egress as 1,2 or 3. For instance in the ditching checklist, fig 3-9 it makes mention for the pilot/co to exit through forward overhead hatch and the LM to exit through the rear overhead escape hatch.

Thats kind of the way I see it, although I am just one opinion!

Our Maintenance folks have done a fantastic job over the years. This J replacement is about 10 years too late.

Now we have a bunch of us trained by JMATS/48th and no airplane to fly until next June at the earliest.

There are a couple of different paint schemes from the camo to the all grey to a mix match of whatever pieces they could find but she keeps flying.

However, I do seriously love the J. Amazing airframe.

17 J-30's comin to Canada with the first set for June 2010.

Can't come soon enough, E's are in rough shape.

God Bless them all.

That is a shame.

I think it may be a generational thing. The kids I transport have not had to experience any sort of "sacrifice". They have not been required to contribute to society in a positive way.

Or maybe it is because they have not grown up in a military environment, so they do not know the value of their freedoms.

I did catch POV's latest program last night. It was about the Bangor Maine Troop Greeters. I wish that school children were required to watch programs like it or participate in something like this - instead of making a construction paper flag or taking a field trip to the zoo. I'm all for making a construction paper flag, but the kids are not taught the meaning behind the colors or history. They just know that they are doing something with glitter and glue. And a zoo will always be there, but not soldiers returning home.

Anyways..

When you mention the Military community, I could not agree more. However, where the vandalism took place, it is very close to one of Canada's largest Army training bases. So it is so baffling.

You are correct about the zoo, they will forever stand, unlike our fallen.

We have repatriation ceremonies here in Trenton as the remains are sent to Toronto to the coroners office.

The link below is on you tube and is titled "The highway of heroes" It ia played at my son's school each rememberance day.

So hopefully the upcoming generation will be more respectful and sensitive to such issues.

I hope the link works, if not, just type in highway of heroes into you tube.

Have a great day

Rememberance Day as it is known up North here is widely popular.

However, in New Brunswick 2 days ago, someone smashed the cross on a nearly 100 year old cenotaph.

It makes one wonder, why anyone would treat such a sacred symbol with disrespect. It represents our fallen who gave these hoodlums the rights they have today!

I just shake my head.

Same back at ya from north of the Border!

You seem to have had a direct personal connection with the winch. Do you recall the structure holding the rewind limit switch? Was it a coil spring/wobble plate arrangement, or a rigid sleeve with the switch on the side? what model Herc were you operating on and during what years?

Hey guys;

I am new to this forum. If you are referring to the Western Gear winch, it would be the spring and spring cup. when the cable was rewound too far it would compress the spring and rotate a plate against the in limit switch.

I just qualified on the J model out of JMATS/48th (Little Rock) and the Able winch seems to be much more efficient.

I was on a trip some years back doing a pers/wedge drop and had a winch get pulled off the wall, thankfully there was type VIII nylon preventing the winch from leaving the aircraft.
