  1. The Trap can release under circumstances similar to all the other non-Infinity MARDs.
  2. They were going to die anyway. If you leave the rigs in the cockpit when you exit on the ground, you'll leave them in the cockpit when you exit in the air. It's just muscle memory and habit.
  3. You know what else is insane? Believing this is common.
  4. I can't think of a single DZO or instructor who is looking forward to a bonanza from recurrency jumps.
  5. Walt/Jerry -- are you sure you're not thinking of the RI Aviator, which does have a 15-year service life?
  6. I agree -- except I think there will continue to be a possibility of new contamination once we start jumping again. We need to start thinking about what the protocols will be.
  7. We don't have a good way to protect or clean virus from textiles (attachment below from US Army). If you are cleaning around your parachute equipment, you should protect your equipment from aerosols, droplets, or other cleaning agent contamination that could damage the material. Many cleaning products are adverse to nylon. To see examples of what might work and what doesn't, you can start with the following page: https://www.calpaclab.com/nylon-chemical-compatibility-chart/ . Finally, some cleaning agents are adverse to our metal hardware, particularly bleach and chlorinated cleaners like Clorox wipes (attachment below from Bourdon Forge; the important paragraph is near the end).

  8. Precision declines to service reserves more than 20 years old.
  9. Could be used for packing toward a rating without worrying about the factory-advised (but not FAA-enforceable) service life. $900 is kinda steep for a training aid, though.
  10. The OP asked for advice about his particular situation. He didn't ask for advice about anybody else's situation.
  11. The Starmaker PopTop chest is exactly the same container as the Strong Seat, just without a harness attached. Packs exactly the same way: line stows, canopy stack/routing, everything. The packing instructions show a Strong 26' LoPo in both cases. The same container was used as the reserve container on the original SST.
  12. Not exactly. For AFF renewal, you have to have done in the previous 12 months: 15 AFF jumps, taught an AFF FJC, and attended a renewal seminar. Some instructors may not have the opportunity they were counting on this spring to meet those requirements.
  13. Not exactly. There's jump currency, and there's instructional currency. For example, you're current as a D-license holder if you've jumped in the last 6 months, but to be eligible to renew your tandem rating, you need to have done a tandem in the previous 90 days.
  14. No I don't have a better solution. I'm going to count that as 3 votes for temporarily lower standards (yours, mine, and the OP).
  15. Is this the place for starting that discussion? The currency requirements are based on the idea that skills decay over time. The decay occurs regardless of the reason why you unable to jump. Pushing deadlines back suggests either that we should accept a lower standard of proficiency and safety (at least this once), or that the standards are too high.
  16. Might still be available from Jump Shack. Earlier this century they partnered with Sonic to build a BASE rig with TSO'd harness. Snap on the Pop-Top chest to make an FAA-legal rig, leave the Pop-Top behind to make a non-FAA jump.
  17. I think it could be done with a little bit of harness modification.
  18. Have a rigger open the rig, take out the AAD. Close the rig well enough to ship, ship it. Sell the AAD, buy another in Germany. There is no loss in this transaction, since AADs depreciate on a straight line, unlike most other consumer goods. You lose the cost of opening and closing the rig, and a pro-rated part of the reserve packing cycle.
  19. Your cell phone and your laptop have lithium ion batteries too. Who is saying you can't transport lithium batteries?
  20. Do you intend your reply to be different? Because it is the same as sundevil777's.
  21. Yes, for rigidity the optimum angle for the cross-brace is about 45 degrees. By contrast, think about the lack of effectiveness of cross-bracing at the tail. Some canopies cross-brace just the forward part of the cell (Icarus NEOS, for example), and some canopies add false ribs at the tail to keep the as-flown shape closer to the as-designed shape (PD Valkyrie, for example).
  22. An early, somewhat successful version of crossbracing was called "airlocks." The chamber-spanning fabric of the airlock valves had the effect of crossbracing the most critical part of the airfoil.
