    My friends.

    I have my first :Phelicopter jump coming up from a Bell 206
    I think it is equipped with double skids to enable us to hang on for dear life ..... We hope to get 5500ft.

    Jumping at a busy DZ that I am familiar with.

    What should I take into account when planning the jump (except for having fun and pulling &:)
    Thank you in advance.



    I don't recommend this.
    Climbing down to this position is dangerous, you can snag straps and/or pull reserve or cutaway handle.
    There is a video on youtube of this happening, the reserve beeing pulled while hanging on the skid.

  3. I have tested the one I have. It's a $99 setup including shipping.
    It claims to have 1200 m range.
    We could talk when I was at 900 m and the other person on the ground. (Was not directly above either)
    It might have worked at a longer range but 900 m was when I was under canopy and we paired the devices.
    When used at more than 6-700 m the sound has a "digital sound". Usable most of the time but sometimes you can't hear.

    Sound was ok, little low. But mine is mounted behind the padding so there is room for improvements.
    There was no windnoise at all. If you didn't know it you would think the other person was on the ground or indoors.

    Sometimes it's hard to connect it to the other device and it needs to be turned off and then tuned on to work, but most of the times you just push a button.

    Used it a few times with both devices in the air and it worked fine.
    Nothing to complain about there.


    For the price, it's great.
    But I'm sure there are others that are better.

    If I were looking to buy an AAD, I would look for a unit that would not fire in a plane or get confused, and I would be curious as to how it was able to do that.



    It's an interesting exercise that people should try... What are your priorities for an AAD?

    Personally, my first one is that is must not fire when it shouldn't. Second is having no unsafe failure modes.
    Third is firing when it should...

    those are mine. What are yours?

    One of my priorities is the ability for ME to set the activation altitude above a minimum. I can't understand why stock units are set to fire at 750 ft. The Vigil II+ can be set higher as I understand. My lowest opening was at 1200 ft way back when. That was pretty damned scary.

    You can set the altitude on a Cypres also.
    Don't know about M2.

    Learning to Swim properly, doesn't interest me

    While Skydive interests me.



    Looking at google maps, if the main landing area is where I think it is, it's about 500 m to the river and about 1000 m to the beach.
    It's not impossible for a new jumper to land that much off, but because it is something you really don't want to land in I don't think it's an issue.
    Generally, if you have a large landing area and a large and good out landing areas students land off because they 'can'.
    Tighter landing areas make them more focused.

    Generally...

    Here is another article about jump-planes that are older than their pilots.
    Have you ever looked at an airplane as a bauxite-based life-form?
    There is a good article in today's AvWeb about corrosion is slowly destroying the general aviation fleet.



    Do you have a or should we guess what article it is? ;)

    They wrote, that the height is displayed in realtime with no processing to make it "stable" but i think there will be an update for it.
    And yes, its barometric.

    Compared to flighsight i think about some differences:

    No additional mount
    No additional gear to check and maintain
    Cheaper (99 Dollars)
    Less afterwork to merge data and video.
    Dead simple :)

    Sure a FS has many other great things to offer and is a great tool (gimmick) to.

    The one thing I really miss with the AltiForce would be displayed speed, but I hope for future changes :)

    For mem it's mostly some new gimmick to test and play with :)

    But right now I'm still waiting for shipping.



    Still, it's $99 for data you can get from your digital altimeter or dytter (depending on which you have).
    Also, with the fantastic batterytimes the GoPro have, I bet it will last two jumps ;)

    ******Here is a picture of the setup potatoman was suggesting, also from United Parachute Technologies. This would probably be the best way to go.



    But with this setup you will not have the same flexibility.
    You have to disconnect the static line/bag and connect a PC to use the rig in freefall.
    With a throw out SL setup you only need to disconnect the velcro and close the rig as usual.

    Just depends on how badly you want to do this. Anyways, I can detach and reattach my Bridal in a jiffy. The static bag is loose anyways. (You cannot really do this with normal gear, you require elastic loops on the outside flaps to keep the static line in place)

    Sure you can!
    Not sure if it's visible on the video, but we used normal student gear.
    You give the SL to the student and tell them, "hold this".
    See?
    We never encounterd any issues.

    And if the pin/static line cable got pulled it's easy to close and not as spring PCs


    ETA: Over here replacing the bridle is a riggerswork, which makes it even less convenient

    If anyone has jumped one of these things please post some info on it. I am looking to use it for general skydiving activities and for canopy altitudes. I am curious how accurate it is and it it uses gps or barometric pressure. I am using a gopro hero 3 black. Shipping time? Customer support? Things like this as it seems like a fairly new company.



    Looking at one of the videos on the page, it seems it has problems with inaccuracis on the altitude.
    probably it's because of the GoPro casecreating a burble where the back door lets the air in.

    But really?
    This thing only creates subtitle files, so how does it differ from the FlySight?
    Sure you have to match the video and FlySight data, but it's not that hard.
    FS can also give you more data than this thing.
    I don't really see the point

  12. Why are you all so stuck with spring loaded PC?
    You can use a normal throw out with static line, we did that a few years ago when we had both AFF and static line.
    It was much easier to change a throw out to static line than the other way around because of the spring.

  13. The GPS in a phone is generally rubbish.
    Some time ago someone posted a GPS track from his phone and it looked awful, and the "landing" was ~100 ft in the air.

    My advice is to get a device built for tracking skydivers.
    Or a external GPS device for your phone, not sure it will work as good as FlySight but it will be better than built in GPS.

    Maybe a BaseR container with a static line made for base jumping might work?

    http://www.jumpshack.com/baser.htm

    https://www.apexbase.com/accessories/static-line-take-away-system



    You don't need to buy that stuff from Apex, you can build something like it from a old lineset that will work just as good.
    Even old-must-be-replaced spectra lines can be used if you only want to make one jump with it.

    But still, a PCA is pretty much the same as a static line.
    I don't think the gear and gizmos will be the issue, if you go head low in the exit your feet may tangle with the lines.
    And it wont matter if it's a PCA, Apex static line or home built, if it's a Baser or not. It won't be good.

    A head up exit, 'frankenstein', can make it safer.

    ***Static Lines are used to teach correct body position to students in preparation for them initiating deployment on their own. I don't see how a balloon exit would teach anything. I also dont see an approved static line anchor point on a balloon. Get licensed, then balloon jump.



    Sammie, it's not that crazy.

    A static line is simply another method of deploying a main parachute. If people wanted to pay a bunch of money, dropzones could even offer a static line first jump from a balloon.

    Look at all the pilot chute assist deployments that BASE jumpers are doing. It would be very similar to that.

    "skyh2omedic" is not some crazy kid trying to jump a balloon before he is ready, (although I can see how you might think that). I'm sure he will get good information before he does a static line jump from a balloon.

    Static line attachment points are not "approved" in the sense of their suitability for use with a static line. If a static line attachment point is "permanently" installed on an aircraft, it may need aircraft "alteration" approval and documentation.

    Here's an interesting question. What would the emergency procedures be for if the student got tangled in the static line and was "in tow"? Land the balloon.

    But the BASE jumpers do it slider down/off.
    I'm not sure I would want to try it with a sky main with slider.
    But, I don't know, it may work fine

  20. DSE

    The 3-10 seconds you'd save by doing this is fraught with any number of potential problems.
    -as you mention, no archive.
    -USB is a shared resource, so corrupt files are entirely possible (and probable)
    -Drives that are fast enough to render to are not readily available and not cost-effective. "Cheap" fits most DZ budgets.
    -You couldn't effectively render to a number of USB drives at once.

    It's a good paper plan for sure. Just not very practical.

    This will change over time, of course. We're very near the end of physical media anyway, particularly as available speeds in remote areas become faster.



    3-10 seconds sounds low.
    Even with 10 MB/s writespeed that is only 100 MB file.
    It's possible but it's not HD and/or a short video.

    However you could create a "backup" that auto copy the new file created in vegas directory to the usb media, that will make the process automatic for the editor so that he/she does not have to make that extra step in the process

  23. Ok, this should work. IF your webspace host accept php.

    $URL = file_get_contents('http://skydivingweather.co.uk/weather.aspx?t=351164&n=Darlington');

    $text = get_Table($URL , "

    " , 0);
    $text = str_replace("images/w", "http://skydivingweather.co.uk/images/w", $text);

    echo $text . "
    " ;

    function get_Table($URL, $needle_begin, $needle_end, $offset)
    {
    $begin = strpos($URL, $needle_begin)+$offset;
    $end = strpos($URL, $needle_end, $begin);
    $URL = substr($URL, $begin , $end - $begin);
    return trim($URL);

    }


    ?>





    And as you can see it's not that much code.
    The actual php code is between . But the link-tag between the head tags are very important. If you copy paste it to a html code don't forget that line of code.


    $URL is just as it sounds, the URL you wish to grab.
    $URL is all the html code from the page as one string.


    $text = get_Table($URL , "
    " , 0);
    This calls a function, the function is placed below the code.
    The functions have four values. $URL, $needle_begin, $needle_end, and offset.
    Don't bother about offset, it's just something I made for a different page.
    The begin and end is first word and last word of the text you wish to grab.
    As you can see I use .
    If you look at the skydivingweathers source code, form and /form is beginning and end of the table.


    str_replace replaces the short links the skydivingweather page uses to full links. Because you need full links on your page.

    Echo $text will "paste" the html code from skydivingweather page from form to /form on your page.
    . "
    "; adds a on your page. Because the code in the function stops at , and not after.



    And thats it.. hope you somewhat understand the code.

    EDIT: You should contact the guy running the skydivingweather page and ask him if it's OK to use his data.
    And provide a link to his page to show the source of your weather.

  24. I believe you need php code to grab the table.
    Just copying the html code will give you the code for now, but tomorrow the forecast will change, but not your page because your html code is static.
    Html code is like a book, each time you open it it will look the same.
    Weather is not the same.

    I'm on my phone now and can't look at the code on skydivingweather site, but most likely I have a finnished php code that can grab the stuff you want.

    I have also made a weatherpage that grabs data from different sources and compiles it, I'm quite sure it can be used or modified to your needs
