    You've been practicing rear riser landings up high, so practice the transfers - even if you don't intend to use it you may need to one day.


    True, helpful and loaded with knowledge by own experience.
    Your posts are among of the best in this forum.
    (and I fly Icarus canopies) ;-)

    Maybe a small intention from me:
    the threadstarter should go and have a good (!) canopy coach before starting to do own try and error landings ...

    Learning that you have more than 2 toggles and 2 risers for flying (and landing) your canopy is important and may save your life.

  2. Hey Micke, you old Bautasten ...,

    just imagine you have been in that plane (Porter roll).
    You know that the exit is on the other side ....

    Pic was shot from a freeflyer who was last out to make a pic from the Porter ... usually he does a sit exit like on the white Porter pic.
    He showed it to the blue Porter pilot and he added some more ..

    For your case, talking to pilots before something like that is always a good idea.....

  3. For me it worked best with my team if we had a 10 round session (1,5 minutes per round) with 2 rotations of others between, so we could review our round on the screen and walk through the next round before entering the tunnel again. Mostly it was a freefly round or firsttimer round, so 2 minutes between our flights.
    Means in total: we needed a minimum of 30 minutes to complete our 15 minutes flying time, up to 45 minutes if there were more flyers with us. With that, usually we were able to fly 2 hours/day without any problems.
    As we mostly have been in prague, review on the screens and preparing inside the chamber before entering the tunneltube itself was easy because of the tunneldesign.
    Also if there was no rotation with others at our specific session, they shutted down the airflow so we could fly with a small break between our rounds.
    With an orga like that, if you start early with a coach on 1-1 and you give yourself an hour or slightly more between your sessions, flying 4 sessions with 15 minutes flying time during the day should not be a problem.
    A good coach will give you enough time to prepare in the creeper area/room before entering the chamber and will take care of a good debrief afterwards on the screen to prepare for the next session. One hour a day flying time with about 8 hours in total of briefing/debriefing/wating between rounds/eating/drinking ... then seems to be comfortable even for new tunnel rats..

  4. If you have to make sure that your expensively trained specialists have to solve a mission where they never have been before and you don´t want to rely on weather conditions for flight training, also you really want to "train" malfunctions under the most realistic circumstances and you can afford the money, then those VR simulators do a great job (I guess).

    For civillian use, if they were the price of a cellphone, they would also be an advantage, why not?
    Just imagine not only for students, also downsizing could be simulated more realistic and CP might go to another level in training :P
    Or a multi-user CRW training ...

  5. How many cutaways are you planning per season?

    Here is how it works and maybe this explains the idea of having maintenance after 3 uses.
    For me, I like the idea of not having a solid peace of metal at my reserve bridle.
    but that is up to everyone to decide for him-/herself.

    I´m jumping Mirage since years and have a cypres.
    If I would have started with my first gear, imagine having a Mirage and the TRAP 28 years ago, I still didn´t have to send it back for maintenance (

    To quote the classic UK TV Show "Red Dwarf':

    Rimmer: "But how did they build such massive, massive pyramids?"
    Lister: "Whips, Rimmer. Massive, massive whips."

    Uhmm, well, that´s not quite true to a 100%.
    the whip-swinging man, forcing the jewish slaves to work on the pyramids is, due to scientists, a picture coming from hollywood.
    Keep in mind, that for example the gizeh pyramid was built around 2620 till 2500 b.C. ...
    the exodus of the israelites took place under Merenptha, the successor of RamsesII, around 1220 b.C., this was also the first time outside the bible , where the phrase "Israel" was published.

    in fact, the -usually poor- egyptian workers did their job because it gave a salary, food and drinks, but most of all: they wanted to honor their pharao. the workers were poor, indeed, but with that work they received public honor as well as money and food. if they died at the scene, they had the privilege to be buried next to the pyramid and their loved pharao as well.

    But to be true, the technical construction of pyramids and their buildings are still not clear how it was done in detail.
    Unfortunately, Alexander the Great has destroyed almost all the collected informations of the ancient egypt scientists 400 b.C., the rest of the saved books were destroyed as the great library of Alexandria vanished somehow (still not clear how or when).

  7. +1
    good explanation.

    most of us think about stall in the picture of slowing the canopy more and more until it collapses.
    but stall is dynamic as you explained.

  8. In my experience, tunneltime for "students" (which are mostly firsttimers or newbies) is meant to get them into good bodypositions, teach them to deal with airflow, practicing turns and forward/backward/upward/downward movements.
    timers in the tunnel are for the organisation and the instructors to know when you have to leave the chamber .. ;)

    Of course the tunnelcrew doesn´t want to have altimeters or such stuff get loose from the student (or experienced) and rush into the fans of the engine ...

    I do not see the need for a kind of altimetercheck/ -display as I would suppose that to be a part of the AFF program at the DZ.
    dealing with the remaining time, giving signals to both (or one) AFF I fits more into groundschool on the DZ ...

    But what do I know ...

  9. a well performed track is a result of the body-position in general, not neccessarily adding bootie surface.
    show perfect execution.

    To your thoughts of adding surface:
    the performance comes from the de-arching and catching air at your legs while the whole body is in the shape for sliding forward and falling slower.
    pointing the toes outward will not push you further, but make it more difficult to de-arch.
    try it on the ground.
    lay flat on the packing mat and try to press your shoulders towards the ground, then lift your lower back with toes pointed straight and then try it with pointed outwards.
    feel the difference ....

  10. how about that ....
    make it full screen on a tablet and start it from the outside by a helper?
    Ok, not very amazing and only for 11k feet and ends at 3k, but for free ;-)

    Or film a student altimeter training device from 12k > 0 and play that video on a tablet
    something similar to that:

    .... I am not doing anything crazy, just practicing stalls and flat turns...
    Sometimes when I do full toggle stalls, with uneven toggle input it would give me linetwists which I was able to clear no problem so far. But it is always in the back of my mind, what if I can't and will need to chop?

    Just for my understanding (and aside of the topic of loosening a cheststrap):
    stalls with uneven toggle input and resulting linetwists?
    Not crazy?

    Okay, flat turns are good to know ..
    But I thought that stalling and twisting is gone, since the videos from Wally Gubbins are out of style ...
