The official number is 400ft but I've heard anecdotes that there have been successful deployments lower. That said, I see this being operated in the "dead mans curve", ie well below any effective height, for a significant portion of it's flight

Surely there are flight patterns that can minimize this risk: ie diagnostic hover at 10ft for X seconds to rule out start up failures, followed by an ascend to 500ft, flight path maintains that height, similar pause prior to descent on landing...

This is usually done in helicopters, but it's not straight up and hover but instead a departure over the runway with forward speed. You can use that speed/energy in an emergency like losing an engine.

There are also enough false deployments that caused harm with these parachutes (edit: instances where pilots didn’t deploy when they should have) that the jury is out on how much of an improvement these are to safety, overall. Operator skill and training is a big factor and this product isn’t targeted at highly trained pilots.

I haven't heard of any deaths as a result but I'm sure there are a few. Usually it's just a hull loss.

That said, this looks like another Icon A5 situation...

I don’t have great sources, so take my claim with a grain of salt. But overall this analysis of Cirrus incidents over 25 years [0] was interesting to read.

In response to fatalities and pilots choosing not to use the parachute when that could have saved lives, Cirrus improved training and saw significant safety record improvements.

> By then, Cirrus had already upgraded its training twice, eventually pulling it entirely in-house. All new-aircraft buyers take it.

They also have training for the used market, and saw owners that didn’t do it often had worse safety records.

Since a Cirrus has a wing, the parachute is primarily a super last resort.. the passenger safety training I took even said it’s mainly to be used if the pilot passes out and a passenger engages it.

The jetson doesn’t have a wing, so I’m happy they have this parachute. I hope they can offer great training too.

The new Garmin Autonomi system is designed so that a passenger can push one button to land the airplane if the pilot passes out.
