The Skydiving Handbook - Chapter 1 (In the Aircraft)
Every skydive starts before you board the airplane. Before you get on the airplane, you should be totally prepared for the jump ahead. This means that you know exactly what you are going to do on the jump and have had your equipment inspected. Make sure you have your helmet and goggles, remove jewelry and take sharp objects out of your pockets, tie your shoes tightly, and so on. Each jumper is responsible for their gear, and you should always check to be sure you have everything necessary for the skydive.
Another part of the ground preparation is being ready to board the aircraft on time. Jump planes are just like airliners: they can't hold up twenty people because one wasn't ready. At the start of your skydiving progression, your jumpmaster will usually take care of reserving your slot on an airplane after you are completely trained and outfitted with the necessary equipment. It is then your responsibility to stay in the area and gear up at the appropriate time with your jumpmasters.
Before you Board:
1) It's too late to ask questions once you are in the airplane, so before you board know exactly what you will do on the skydive and review your emergency procedures. On the ride to altitude you should review the dive mentally, imagining a perfect performance. Keep in mind, however, that you are not compelled to jump from the airplane just because you happen to be on it! If you realize on the aircraft that you are not ready to jump, you may ride down with the airplane.
2) Check your gear. Your jumpmasters will help you to be sure everything is correctly routed. Be sure your altimeter is set to zero, your goggles are clean, etc. If you will be boarding an airplane when its engines are running, keep a good grip on your goggles and gloves!
3) Stay close to your jumpmaster and away from the propellers, other aircraft, and any other hazardous objects. Remember that the pilot may not be able to see you when he is taxiing the airplane; he always has the right of way.
Once you are in the airplane, sit where instructed. Be sure to wear your seat belt until you are high enough for an emergency exit. It is also a good idea to put your helmet on for the take off. Your two responsibilities in the airplane are to minimize movement and to protect your deployment handles. Avoid snagging not only your equipment but that of other jumpers. Until we are on jump run you should stay seated. Then, at the jumpmaster's command you can get to your feet and move carefully to the door. As you move about in the airplane, watch out for door handles, emergency exit releases, seat belt buckles, etc. While inside the airplane your job is to protect your parachute!
Most of your jumps will be done from our larger, twin engine airplanes. Exactly which airplane depends on how many people are jumping and the aircraft maintenance schedule. You should have familiarized yourself with the aircraft door, handles, and steps before boarding. Most of the time the more experienced jumpers will exit first for a simple reason: students open their parachutes higher than experienced jumpers. To preclude the possibility of jumpers from different groups colliding, exits are staged several seconds apart and planned with the opening altitudes in mind. That way we get both horizontal and vertical separation between groups. If you are leaving first because of unusual circumstances, have your jumpmaster fill you in on what to expect.
The jump run itself is flown into the direction of the wind. This gives the airplane the slowest possible ground speed . In other words, it is over the drop zone (DZ) longer than it would be if it was running down wind. The pilot uses GPS (Global Positioning System satellites) to tell him exactly where he is, and when he is over the spot , or correct exit point, he turns on a green light back by the door, telling the skydivers to exit. Should the exit sequence take so long that the last to leave might not make it back to the airport, the light will go off, indicating that the remaining jumpers should stay in the airplane for a second pass over the drop zone. Incidentally, since you will usually be getting out late in the line up, and since the jump run is into the wind, you have a way of knowing which way the wind is blowing as soon as your parachute opens. Imagine a line from the landing area to a point directly below you. That is the wind line - if the pilot was right about the spot.
