Altitude Awareness

Recommended Posts

The other day a funny thing happened to me that may open a few eyes.I was on a two way freefly jump that broke just a tad low (4000ft instead of the planned 4500ft). I tracked off, cleared airspace and noted my altitude at 3000ft.I pitched immediatly so I'll guess actual pull altitude between 2600 and 2800 ft. My canopy began to snivel for quite some time with the left side folded under the slider. I watched it expecting it to spin but it did not, and it still continued to snivel.I thought to myself, " I have to be getting low" so I reached for my handles.About that time, it opened. I quickly checked my airspace for other canopies, collapsed may slider and unstowed my brakes. Only then did I look at my altimeter (remember the last check at 3000 ft ?). My altimeter read 1000ft, too low.The moral of the story is pay attention. Things happen fast and you can lose track very quickly. With todays slower opening canopies, a long snivel can mean a lot of altitude.------------------------------

Please elaborate, Randy. That sounds from your description like an ABnormal deployment ... aka malfunction-in-progress. Do you still do a '5 count' after you toss and then check canopy and alti? Was it indeed a strange deployment ... were you considering a chop at any time? Did you pull your rear risers in attempt to help speed inflation?What main do you fly?

'breaking low' and 'abnomal sniveling' are two links in the Chain of Events ... good thing there wasn't a #3 like a very bad spot with no outs. I've been low on a low breakoff myself and my only path back to the main LZ was over nasty stuff and I was low enough to be a bit concerned.

Thanks for the reminder - we all need that sometimes. Glad it worked out.

Yes Dave I would call it an abnormal deployment. It's kind of hard to explain other than the way I did. The left side of the canopy was literally folded under, blocking the slider, yet the canopy was perfectly on heading.
I fly a Jedei 150 , loaded at 1.4. I don't normally do a five count, because this canopy is generally fairly predictable. I know this is bad, but I'm one of those guys who tends to "fly by feel" This time I let it go a little long.
As for considering a chop, yes and no.I was taught to keep my legs together and eyes on the horizon while deploying an elliptical main. Only when I realized that it was taking a while did I look at the main. It all felt normal except for the timeframe.
I looked up, realized something wasn't quite right, went for my handles and it opened.

Anyone care to comment on that statement? I've heard contradicting remarks about that same thing. Some people say pulling on rears will majorly slow down openings, some say it makes it snap open.

Personally sounds like an easy way to stall/wrap your canopy around itself. You're working with a lot of kinetic/potential energy with a sniveling canopy.

What do you think?

I'm sure it has a lot to do with the canopy and wing loading you are flying.I was flying a spectre for a while and found a nudge on the risers would speed it up a hair. I have found with my Jedei to just leave well enough alone, as it only makes things worse.

I'll pull in a little bit of rears if I want my Stiletto to finish snivelling quickly. I also do it on CRW hop-n-pop's with no problems.

I apply even pressure and it only takes a little bit.

Again, YMMV, this just happens to be how my Stiletto responds.

I would not consider this as an incident if the canopy does not consistently open in such a long snivel. People, especially on formation loads frequently pass the hard deck while still sniveling. Not a big deal if you are aware of altitude, and ready to chop if it does not open right. 1600 ft to open, check the airspace, collapse the slider and unstowe the brakes isn't too much if you canopy opens really slow. I would bring the pull altitude up or get a different canopy if it does so.
