  1. OK, I’ll bite.
    The problem I have with method 1 (pull silver at once) is that it assumes a ‘situational awareness’ on the part of the skydiver that may- or may not be present.
    After all you have thrown a pilot chute and are anticipating an opening shock in ‘onethousand, twothousand, threethousand...”
    However the first thing you notice is that you don’t get an opening shock and you keep buzzing towards the planet at terminal velocity.
    Why?
    You misrouted your bridle in such a stupid way that it will break before pulling your curved pin OR You did a lazy throw and your pilot chute is in the burble on your back OR You forgot to collapse the pilot chute AND?OR your pin remains in the loop since you have a tight setup AND/OR your pin is out of the loop since you have a loose setup, however the collapsed pilot does not produce enough drag to lift your main bag out of the container OR Gremlins are messing with your system.
    Now if you jump gutter gear that old farts like me used in the previous century there may be something to say for ‘keeping the 3 rings in place’ and pulling silver at once - what happens next you can sort out under your reserve, hopefully...
    However, since you jump semi elliptical mains and small reserves at wingloads that I would not dare to contemplate back in the days, chances are that once you start figuring out what to do next with that extra canopy, both canopies may have already decided what they will do with you - which is to give you a spin for your money just as you start to grab for your reserve toggles.
    Getting slightly behind the powercurve sucks in skydiving - and can be lethal
    So better take a few seconds to analyse the situation then?
    Priorities, priorities...
    When you cut-away while that was not neccesary since your main is firmly locked in place AND you don’t jump Wonderhogs / Rapid Transit or any other form of ‘vintage’ gear your ‘state of the art’ riser covers will keep your risers away from the deploying reserve. That is what they are there for in all the gear produced in the last 20 years or so. Hey, even well maintained Velcro can handle the job of keeping your risers in place, not interfering with the deployment of your reserve. You might want to figure out where an RSL would end up but unless you jump with systems that deploy the reserve automaticly on one occasion and chocke the reserve when things go slightly different on another, your RSL is safely tucked away and even when your main starts to deploy right now it likely will not interfere with the airworthyness of your reserve.
    This cut-away before you pull silver adds TWO WHOLE EXTRA SECONDS to your EP’s.
    Figuring out what the Gremlins are up to might take the rest of your life or just the time it takes you to get to AAD firing altitude...
    YMMV...

  2. The picture that illustrates the article seems out-of-place since the article sums up emergencies that have in common that your freefall is continued which clearly isn't the case in the pic.
    Also, from a psychological pov - if this is aimed at students (?) - the 'common denominator' of all these emergencies is that "stop the skydive" is the most urgent thing on the students to-do list, not fruitlessly analyzing (hampered by tunnel vision) if that is a pilotchute hesitation or a pilot chute in tow which causes the student's continuation of his 200km/h race towards 'terra firma'...
    Furthermore, the article promisses "a detailed explanation of these three systems" (throw out, pull-out, springloaded) for which the reader should look in "the chapter on equipment".
    Where?
    Whatever you think of the DZ.com forums, most 'afficionados' there do agree that learning to skydive 'online' on both youtube and DZ.com is a bad idea.
    So maybe that also goes for posting 'informative' articles on this crucial learning subject on the main pages of this website...
    YMMV.

  3. This is a great idea when you look at it from the perspective of 'rule making' - even if you want to celebrate your optimal freedom and only live by 'rules of thumb/dumb'. However, like the famous 'do not take a camera with you unless you have xx jumps' I could also see something happening like 'do not exceed a ratio of 0,xx' in the volume of your parachute divided by its area unless you have xx jumps'. It is clear that this ratio which ranges from 0,42 for Big Air Sports smallest canopy to 0,65 for its biggest one could give you (and those trying to prevent you from hurting yourself by making dents in their dropzones) an extra handle when assesing your ability to handle a certain canopy.
