> Is paramotoring safer (i.e., longer life expectancy) than paragliding?

The stats are skewed in favour of paramotoring, althout the added complexity means more margin for error. The safety plus to paramotoring is that you can fly on a day without any wind, while paragliding requires at least a 2 m/s wind to descend from the top of a hill or moutain and about 5 m/s to soar next to a slope, dune or ridge. Paramotorists also rarely engage in aerobatics which is probably why the stats are skewed. They also almost never need to perform special altitude loss procedures like big ears, tip stall, B-line stall or spiral dive.

This is untrue, paragliding doesn’t require any wind for descending. You generate your own airspeed. There are also other ways of staying up than soaring (thermals). Additionally, wind isn’t the source of the risk, rather wind variability and turbulence. Flying in low wind doesn’t add to the risk profile.

Yes, you could take off in zero wind and fly off a cliff but it's quite boring. I wouldn't even bother hauling my paraglider up a cliff on a windless evening when the there are minimal thermals. Not without a lift. The risk profile is is quite debatable. But the general consensus is that paramotoring is safer. I see it simply carying other risks, like tangling your lines in the propeller, improperly operating the engine etc. Also the number of yearly fatalities is smaller, which doesn't actually say anything without total hours of flight. For paragliding I think most uncontrollable risk mainly revolves around weather.

Hmm, so maybe one reason paramotoring is safer is that the safest time to go paragliding or paramotoring is when there's no wind and thus no wind shear (etc.), but that's inconvenient and boring for paragliding?

Estimating total hours of flight in the US seems like it would be difficult since there's no licensing regime.

Yes, pretty much. Once can paramotor on a flat field with no features on a clear windless day. Plus there's no need for altitude loss procedures which carry some risk, no aerobatics, the wing is almost always properly loaded because you carry a 30 kg motor on your back and you don't need all the wing area that you normally need for paragliding, so the risk for wing collapse is smaller. There are simply other risks involved.

I would disagree on boring, thermal flying on a windless day is amazing, proximity flying, a chill sled ride. Many fun ways to play without wind.

I wouldn’t comment on safety comparisons with paramotoring without more statistics.

Thermal flying implies wind or updraft.

I haven't found any proper statistics, just fatalities without hours of flight for each activity. Which are really just anecdotes masked as statistics.

Sure, but you’re twisting words. Wind is pretty much always used to refer to horizontal air movement.

Thank you!
