    Looking for reasonable justification of four year maintenance costs from cypress.

    Beyond the obvious 'what is your live worth' pat answer, I wonder why I'm being charged $119 for inspection and no problems found.

    Any ideas?

    In detail, what is performed on the maintenance?
    1. When we receive a unit for its maintenance, its details are first recorded in our data base. All relevant data - such as serial number, current owner, reason for returning, etc. - is entered. With all units, the complete history is stored in this data base.

    2. All cables are visually and electrically inspected for wear or damage. The next step is to open the casing. From here the unit runs through the individual stations.

    3. The plastic processing unit case is split apart and the internal metallic electromagnetic shielding unsoldered and removed.

    4. If updates (technical improvements) are applicable on the unit, they are automatically performed. Every unit is subjected to extreme heat and cold conditions in climatic chambers.

    5. During this, all functions and power consumptions are tested and measured under all possible conditions. A great number of simulated test flights are performed, where the unit must NOT activate. Also, the unit is subjected to simulated conditions which cause it to activate, thus testing the activation programming and data (electronic cycle, precise duration and magnitude of activation impulse).

    6. The technical data is compared with that from the original production phase. Any deviations or discrepancies are analysed and appropriate action taken.
    Additionally, the data is compared with data from other units from the same manufacturing period. This is the reason why we request the CYPRES units to be returned for maintenance at the due date -plus or minus the leeway of 3 months

    7. The cutters are also comprehensively checked - both visually and electronically. The plastic slip which the loop is routed through is checked under the microscope.

    8. Once the unit goes through all tests successfully, it is re-assembled. When this is done, the unit goes through the testing procedure again to ensure that the rebuilding of the unit has had no influence on the unit’s function.




    $120 seems like a reasonable cost for this service. YMMV.:)

    It's a linear scale... if it's discreet I'm ok. But that Mimi character from the Drew Carey show... Gahhhhhh!>:(

  7. Yes. The information is available on the Airtec website. Click the services button and scroll down to "Model change 1-pin <-> 2-pin"

    Use in a 1-pin reserve container and the use in a 2-pin reserve container
    All CYPRES can be used in both container types.
    Through the plug-and-socket cutter connection a swop from 1-pin cutter to 2-pin cutter or vice versa can be simply done by pluging-out and pluging-in without opening the unit and without use of any tools.

    I have been using Adobe Acrobat 8 to fill in the PDF's of my college applications. Works okay when you use the type writer function. You basically just make a text field and write into it.



    That's what I do too.


    I believe the EULA for Adobe Acrobat allows installation on two machines. If you have a friend... (hint hint);)

    Seriously. I just had a look and it looks like the home page to MSNBC or CNN. Does everyone really only monitor this site and no other? Do you really think that we all missed that GREAT BIG HEADLINE on any one of the other sites we might click? Anyone remember when we had original threads?

    [/rant]
    Just wondering and I had an extra .02 to contribute. B|




    What is this 'originality' you speak of?


    why not make a skydive?:P

  13. You made the right decision.:)
    Keep your focus on the team training- the Stiletto is a big change from what you're used to and it would pull your focus off of your goal.

    The article covers the basic physics that apply:

    "To begin to understand lift we must return to high school physics and review Newton’s first and third laws. (We will introduce Newton’s second law a little later.) Newton’s first law states a body at rest will remain at rest, and a body in motion will continue in straight-line motion unless subjected to an external applied force. That means, if one sees a bend in the flow of air, or if air originally at rest is accelerated into motion, there is a force acting on it. Newton’s third law states that for every action there is an equal and opposite reaction. As an example, an object sitting on a table exerts a force on the table (its weight) and the table puts an equal and opposite force on the object to hold it up. In order to generate lift a wing must do something to the air. What the wing does to the air is the action while lift is the reaction."

    And it explains the boundary layer and laminar flow of air around the wing:

    "The natural question is "how does the wing divert the air down?" When a moving fluid, such as air or water, comes into contact with a curved surface it will try to follow that surface. To demonstrate this effect, hold a water glass horizontally under a faucet such that a small stream of water just touches the side of the glass. Instead of flowing straight down, the presence of the glass causes the water to wrap around the glass as is shown in figure 8. This tendency of fluids to follow a curved surface is known as the Coanda effect. From Newton’s first law we know that for the fluid to bend there must be a force acting on it. From Newton’s third law we know that the fluid must put an equal and opposite force on the object that caused the fluid to bend.

    Why should a fluid follow a curved surface? The answer is viscosity: the resistance to flow which also gives the air a kind of "stickiness." Viscosity in air is very small but it is enough for the air molecules to want to stick to the surface. The relative velocity between the surface and the nearest air molecules is exactly zero. (That is why one cannot hose the dust off of a car and why there is dust on the backside of the fans in a wind tunnel.) Just above the surface the fluid has some small velocity. The farther one goes from the surface the faster the fluid is moving until the external velocity is reached (note that this occurs in less than an inch). Because the fluid near the surface has a change in velocity, the fluid flow is bent towards the surface. Unless the bend is too tight, the fluid will follow the surface. This volume of air around the wing that appears to be partially stuck to the wing is called the "boundary layer"."

    Not sure if this statement is true at all. My home DZ does a lot of Tandems . I don't see people limping off the LZ

    It was more along the lines of "why don't the majority of tandem jumps stand up"? I'm really new to the sport, is it because of the equipment? I see most AFF jumpers stand up on their big student canopies, why aren't tandems masters standing up with their massive tandem canopies?

    These are legit questions, I have no idea... I would have assumed two people, twice the weight, twice the size of the canopy and all was fine and dandy to flare in perfectly to stand up everytime?

    Don't take any offence to this anyone, I only learn by asking questions.



    Read some threads in the instructors forum.

    Part has to do with training... the risk of 'trying' to stand it up is the consequence of not 'standing' it up. Anything could happen... and if the student mis-times it (sets their feet down first) ?

    think of it like a pilot... if the 'nose gear' touches down first there is a greater risk of the 'plane' doing an endo.... hence a face plant for the 'nose gear' on a tandem.[:/]

    my training (by the mfg) included not attempting to stand up landings... (it's largely skill and timing) grass on the DZ jump suit is no big deal compared to an injury to you or the student. YMMV
