He is not saying that general aviation pilots should not have any parachutes available, or that they should never use them - he is saying there is no reason for such pilots to wear them during normal flight (and the fact Jacob was wearing one is evidence that he anticipated having some sort of "problem" he could use as an excuse for bailing out right away, instead of aviating).
This is the same argument that people make about carrying firearms. (Why do you carry a firearm when its so unlikely that you'll need it? Are you looking for a fight?)
Jacob specifically said he was bringing a parachute because he was worried about flying over the mountains. And this is a legitimate concern, which this Hornfeld dude just completely dismissed. He spent half the video criticizing him for even bringing a parachute. He even further criticized him for bringing a "sport" parachute, which by any measure is a better life saving device over dangerous terrain than a standard parachute. (Why did you bring a rifle? Is a handgun not enough?)
If I'm gonna fly over the mountains in a single engine, I'm bringing a goddamn parachute, and if I have a sport parachute, I'm bringing that. This hornsfeld dude - as I said at the start- was overly critical of this decision.
If Jacob had attempted to aviate & navigate but had been unable to find any viable landing spot, then it would have been appropriate for him to have abandoned the craft in-flight.
Again, not
once did Hornsfeld say it would have been fine to jump out if he had just "aviated a little longer". He did however spend a great deal of the video criticizing the decision to even bring a parachute.
And by the way - its the pilot's decision and the pilot's decision alone for how long one needs to "aviate" before jumping out. If he felt safer to jump out at a higher altitude, and there was no substantial safety benefit to others by further "aviating" (and there wasn't), who the fuck cares how long he "aviated" ?
Yes - he expected Jacob to try to land his still-flyable, still-landable plane in this situation. He is criticizing Jacob for not even trying to do so, contrary to the standards CFIs teach their PPL students, and for immediately bailing out instead.
Just because it's "landable" does not mean its safe. 10% of forced landings are fatal - and that's in average conditions. In mountainous conditions, that number goes way higher.
Jacob had no obligation to even "try" to land.
Despite hornsfeld's handwaving of the "perfectly suitable landing areas", any forced landing in the mountains is going to be extremely dangerous.
Neither Hornsfeld, you, nor the FAA, has
any authority to try to tell Jacob that he had an obligation to "try" to land, in a situation where it would be
extremely unlikely for anyone to be hurt by an abandoned aircraft.
