Yes, and yes there was sarcasm.

Sorry for the facetious confusion.   I was referring to 'other' DZ activity.. holding your knees together while cocooning keeps you virtuous. 

Gowlerk makes a valid point, but the real reason is to preserve your virtue at least at some times while you're at the DZ.  Lesson is, if you start to flake out, clamp your knees together.  (note: it doesn't really work, but it looks good on the waivers)

That round one in elementary school PE class.

Article contains a description by a tandem instructor in freefall nearby.  Not in danger at all and don't know if he got video, but this may trump your freefall photo near a space shuttle launch.  

 

Take your wallet.  The big one.

N420DZ comes back as a Cessna 208, not a KA.

Thanks to everyone who's contributed to this thread and I appreciate all the thought that's been put in. A lot of interesting speculation has been thrown out there.

To get back to the original question, this is simply about the amount of fuel used in skydiving flight operations specifically. This should be restricted to the number of gallons actually purchased and then assumed to be poured into aircraft. This should be far easier to estimate just by fuel sales.

Discussion about overall skydiving carbon footprints is a bit specious and a speculative rabbit hole. There are too many variables involved. If skydiving ended tomorrow, the people involved would find something else to do that would create their own footprints, therefore it would suffice to call all ancillary carbon impacts a wash.

Dropzone.com published an article earlier this year on this very subject. Previously I had seen estimates that 100 jumps per year increased your carbon footprint about 10%, but based on the numbers in this article it would be closer to 6% (based on an average carbon footprint of 21.5 metric tons, which may not be that accurate).

I dont think you were that far off, big picture.

Excellent article. Thanks for including it. I heartily encourage everyone to read it.
Once again, Bryan Burke rules. Fun fact.. he ran my FJC in 1984 at Orange, VA, when he was a college student. I lived.

Skydiving causes your personal carbon footprint to be much larger than it otherwise would be.

Depends on what you would be spending your time/money on if you didn't spend it on skydiving.
Based on the numbers from the article on dropzone.com linked above, making 100 jumps a year has a smaller carbon footprint than taking a 7-day cruise ship vacation. (Source: https://www.sciencedirect.com/science/article/pii/S0301421510000066) That said, I'm guessing there's not much overlap between "people who skydive" and "people who like to go on luxury cruises," but skydiving probably isn't the most carbon-intensive recreational activity you could possibly do.

Cruising impact didn't even occur to me when we had the discussion. Interesting.

***Does anyone have a reasonable estimate of how much fuel is burned daily in jump operations worldwide, on an annualized average?

In other words, obviously, weekends, boogies, holidays, etc. would be averaged with days when jump ops aren't conducted and in the winter when ops are minimal or non-existent.

I had a debate regarding climate impact with my GF's son about unnecessary carbon footprints and I just threw out a gut assertion that an entire day of fuel use in jump ops worldwide wouldn't even be equal to the fuel used by one 737 trans-continental flight, or one day of commuter fuel use in any of the major metro areas: DC, Houston, LA, etc.

How far off base was I?

Meh if you feel guilty about it plant a couple of pine trees.

You missed my point.

October 1959, I was a naval aviation cadet.
I scronged up B4 back parachute and a chest parachute.
I had some Navy riggers put D rings on the B4 And went looking for an airplane.
I found a crop duster with a Cessna 170 and he took me up to 1500 feet. He didn't wanna fly any higher.
When I could see the DZ I climbed out and pulled.
No Mods, no Sleeve, no Brains. But Saint Michael came through.

You win.

May 19, 1984 - 25yo

I did a season of static-line and one freefall on modified T-10 round parachutes. Then.. took 22 years off due to family/job/dithering around with other shit, etc.

Came back in 2006 at 47yo and went through the AFF program. Still trying to balance family/job but have managed to knock out 800+ absolutely fun jumps (except the one in the rain with shorts & t-shirt ) and don't regret a bit of it, except for not getting instructional ratings to make it a profession.

My father was Airborne (I was born at Ft. Bragg) and probably the genesis of my desire to do the first jump. I simply knew it was something I wanted to do. I recruited a dozen or so co-workers to go along for a first jump course, but of course none of them continued.

Some of the best people I know, I met at the dropzone. It's not all about the jumping. You'll know if you go.

Don't hold back.
Do it if you feel it.
Do it now (or when it gets warmer).
Regrets are forever.

Ok. I clicked on this, thinking it was a Mexican pilot/instructor.
Just ban me now. I've had worse.

If you're a skygod, you can stop the spinny whirlygigs.

AFF = $1600 + $300 or so for cat G and H jumps
That's a bargain.

rig, helmet, altimeter, jump suit, license fee, USPA membership, ect. ect = $4000 (cheap crappy gear) - $10,000 (all brand new)
Don't buy brand new unless you're made of money.

You're looking at around $10,000+ for your first 200 jumps.
This is pretty accurate, but don't forget to factor in beer.

And when that EMP burst hits, the only vehicles left driving will be those with old-school point-distributors. The rest of you will be left waiting for the zombies to bite.

And for the record, WinXP was the bomb. Solid, fast, reliable... just like your old girlfriend.

34 years. However, admittedly, for 22 of those years, I didn't even look at a parachute.

This is the guy to target. Vote him out of office.
Well, it's hillbilly country - southwest PA, so good luck on that.

You think that 2 students in a 4 way is scary? Prior to this recent change (within the last year) a Coach, or Instructor, could take as many students on a group jump as he chose. He literally could take 99 students with him for a 100 way.

I suppose this is why I love you.

******Katanas have relatively low toggle pressure compared to other models. If she's not standing up her landings she should switch to one of those, maybe it will help her.

Worst advice I've heard in a while. The OP mentioned that this a newer jumper. The Katana is an elliptical canopy with an aggressive, ground-hungry design - NOT intended for young jumpers. A newbie should never jump a canopy with those qualities. This young lady is already having problems flaring completely and/or properly. An incomplete or improper flare under a Katana would not be pretty.

This thread cannot be for real. Did I just end up on the sofpidarf page?

Nope. Chuck just got trolled.

Anything with an inflatable.

I believe you should modify your specification for the time to begin once you toss your pilot chute.

I jump Snivelettos, but I pack for myself in a consistent manner. so my experience may not be typical.

Once I toss my PC, it would be unusual for me to not have a solid, flyable (rears), canopy over my head within 5 seconds. That being said, it's a smooth deployment with no line twists/slammers for the last many hundred.

Shit, Now I've jinxed myself.
