I'm just a private but I also prefer to have another pilot along with me for a trip. It considerably reduces the workload and at least there is someone else who can operate the aircraft if something happens to me. A passenger jet is much more advanced than a single engine piston and can cause a lot more damage when it crashes. The risk just doesn't seem worth it and I can't believe any insurance company would allow it. It's a roll of the dice and not a chance I would be willing to take. And besides, it's always better to have another set of eyes and judgement.
A lot of this thread is locked in the paragraph.
You _prefer_. Because you prefer that, it should be the law now?
Yes, it is better to have a set of eyes, and if you feel comfortable when taking another pilot with you, I will be the last person to judge you.
However, just a 172 is designed and certified for single-pilot operation, the single pilot jets are too. I do not have any experience flying one, apart from reading about them. I suspect you have about as much experience in a CJ4 as I do.
Your PPL entitles you to take a plane out on your own. Because you prefer not to, you shouldn't prevent another pilot from enjoying that privilege.
You can fly a PC12 or Phenom Jet etc on a PPL as well. The rule-makers have deemed it save.
Greendot has got a very vocal hatred of the FAA, but not all of the single-pilot planes were built and certified initially under FAA rules. So that means all the countries together in their mandate are just as useless.
Yes, there has been many accidents with single-pilot planes. But not a lot of them were necessarily avoidable just by having two pilots.
How about the Phenom pilot that never thought about turning anti-icing on before landing in ice? Will another set of eyes help? Maybe. Will another set of eyes also forgot? Just as likely if you talking two PPL pilots with a company manual (think privately flown bizjets).
How about the bizjet (I think it as a CRJ derivative) that pranged because they took off with the control locks in place, and the voice recorder revealed they haven't done proper take-off checks for a long time.
You could have 10 pilots in the plane, no amount will make up for bad procedures, lack of airmanship and poor discipline.
