  1. Of the places I've jumped, most pilots will put the flaps down but a few like to run in a little faster. But then I've also been in a Twin Beech trying to stay with a slow flying Caravan on jump run when the Beech stalled with half a dozen 200# gorillas hanging on the outside of it. Of the two scenarios, I'd rather take the fast run in.

    Swoop shorts + tshirts vs jumpsuit

    Jumpsuit for me. No waist band for a t-shirt to pull out of and flap up covering your handles. No exposed flesh that gets scuffed when you faceplant a landing. More drag gives you more range in freefall. It's not even close.

    I think the trick is to wear the tracking suit back to front.

    Newb Jumper Story

    That kind of aggressive manoeuvre can give you line twists on virtually any canopy. The reason is two fold. First you initiate a turn one way and generate some momentum, then you tell the canopy to turn hard the other way. But you haven't given your momentum a chance to reduce so your body momentum one way and canopy trying to turn the other creates a torsion on the lines. The second part is that as you flick one way to the other, the lines lose tension due to the change in lift vector. Put them together and you get line twists. Many people have had to chop the resulting mess. Do that too low and it might be the last thing you ever do. It's kind of important to keep line tension as that is the only thing that keeps you in control of your canopy. Lose that connection and all you have is uncoordinated fabric and string with no way to control it. At normal flight, you have 1G of tension. Any manoeuvre that reduces that tension is heading towards bad territory and if you lose enough tension can cause your canopy to collapse. The main thing is to be aware that this can happen, what causes it and where the limits are on your canopy. I'm sure there will be canopy courses in your area, ask around. Definitely get on one (or two, or three), they'll be the best money you ever spend in skydiving. It's no substitute for a real course but Brian Germain's book "The Parachute and it's Pilot" is worth a read too.
  5. As you apply a brake on one side, you swing out and start to turn. If you release that brake and apply the other, the canopy tries to turn left while you're still turning right. The result can be lost line tension, line twists, a collapsed canopy and if you're unlucky a reserve ride. Sometimes known as cock turns because if you do them and have to chop, you're a cock. Let your canopy recover from one turn before you change direction and keep that line tension, it's the only thing keeping you in control of your canopy.
  6. I'd go for an ordinary barometric alti like the Altimaster Galaxy. Maybe get an audible later on.

    Leg Cramps

    Medical diagnoses should probably be performed by a doctor not some adrenalin junkies on the interwebz who stand around all day calling each other "dude". But seriously dude, it's probably just your harness not fitting right. I doubt it's like deep vein thrombosis or anything serious man.

    Arch Workout

    Arch from the hips not from the back. You'll fly better and your back will thank you.

    QUIET full face helmet

    My Z1 is pretty quiet. Probably best if you can borrow one to try first though.

    Consol jumps at different DZ?

    Your best bet is to call the DZ you plan to do your consols at and ask them. But in my limited experience (and it is limited), provided you have all of your paperwork up to date, including a fully signed log book, medical forms and BPA membership, you shouldn't have any major problems. You might expect to do a review of your EPs and maybe get followed out by an instructor for the first jump if they don't like the cut of your jib. The cut of your jib will be much improved by giving correct and timely answers to the instructors when asked about your training or failing that, by the ritual offering of beer at the end of the day. Play safe.
