Safety: From your S&TA at 7 Hills Skydivers
First let’s talk about winter jumping. Summer is gone, fall is here, the leaves are falling and winter is near.
Following are a few reminders for everyone:
No 1. Don’t over dress. The more bulk you have on the harder it’s going to be to maneuver in the aircraft and the
slower you are going to be in freefall. It’s also going to slow your reactions in case of an emergency. The most
you should wear is a thin set of long Johns, a turtle neck and a sweatshirt. Also the more bulk the more likely you
are going to work up a sweat while packing and that means the cold blast of air is even going to be colder
when you open the door at altitude. Also keep the heat in the clubhouse at no more than 60 degrees. It not only
saves the club money, which we don’t have much of but it keeps you from over heating. While climbing to altitude
keep the heat in the aircraft to a minimum so when the door opens there’s not that huge change in temperature.
No. 2 When it comes to gloves they should be as thin and pliable as possible while still giving you protection
against the cold. Do not wear any bulky ski gloves or hooks. Make sure you can feel and take hold of all of
your handles. An S& TA or an experienced jumper should look at all gloves.
No. 3 Helmets and goggles fog up, especially helmets with a full-face mask. Keep them off until just before the
door opens.
No. 4. When flying relative, don’t plan as many points as you would on a nice summer day. You are going to be
slower and you will not execute as smoothly. Take your time and keep aware of altitude.
No 5. Make sure there is a ground crew so if you land out or get injured there is some one there to pick you up.
No. 6. When jumping in the wintertime and if the ground is completely covered with snow, be aware of the fact
that your depth perception is going to be way off. In other words it is going to be more difficult to judge your flare altitude.
Try to use buildings, trees, the windsock or other obstacles (if you are landing out) to help judge your flare
altitude. It is better to flare a little high than too low. Just remember, if you flare to high hold it at 3/4 brakes and
do a PLF.
No. 7 Equipment check. If there is snow on the ground, part of your packing procedure should be to check your cut away housings and your reserve rip cord housings for ice and snow and any other kind of debris. The last thing we want or need on a cold winter day is a hard pull in an emergency situation.
Let’s talk about RSL’s. For those of you who like to push the limit and jump in high winds, especially if you are doing a cross
country, you should think about disconnecting your RSL after you have done your primary canopy check. It’s easy to land out (and we all do) because of a bad spot, again, especially if you are on a cross-country. If you are getting dragged and no one to help collapse your canopy and you have to cutaway and your RSL is still connected you are in big trouble.
Remember the rule of firsts, always limit yourself to one new thing per skydive, and keep that skydive simple. If it is your first skydive with thicker gloves, layers of clothes, and a face mask keep the dive simple,
include a practice touch, and plan to pull a little higher. Most skydivers don’t fly as well when they’re dressed like the “Michelin Man”, so plan your dives accordingly.
Generally most people lose interest in skydiving when the temperature dips below about 20 degrees. If it’s cold out, and you can’t find people to jump with, it’s probably a good day to visit your travel agent. If we get a big snowfall, make sure the runway has been plowed before heading out to the airport. If the temperature gets much above freezing, then our runway
may become unusable, so stay in contact with you fellow members to find out where they may go to jump.
Other things to remember:
It’s always a good idea to have at least one person on the ground to watch when jumping in the winter. Landing out or injures become a little more critical when the cold is a factor. Snow covered ground provides fewer altitude references. Do not rely solely on the ground as your reference in freefall, use your altimeter. Canopy’s flare better in cold weather, so
anticipate this when you land. Frozen ground does not give, frozen furrows break ankles, frozen corn stalks break toes, it’s hard to run in the snow, a good PLF can make the difference between walking away sore and not walking away from a landing.
