I have a handheld that I sometimes carry with me, but I am not convinced that it is really all that useful. If I am are VFR, then I would rather land nordo at an uncontrolled field, or if I really have to land at a towered field just use light signals. It is much easier than hunting for the handheld and figuring out how to use it. If I am in IMC on a long cruise segment, I suppose one could have enough idle time get the handheld set up, but even in that case it is a convenience rather than a requirement, and I'd much rather avoid the distraction that a handheld could create.
There was once a time when airplanes were much simpler. They had wings, a motor, tail feathers, and a place to sit. They did not require any radios, or navigation devices, heck, they didn't even have ailerons or flaps.
Like all of mans contraptions, other men continued to improve on them. Now today, we have aircraft loaded with so many gizmos, it is hard to imagine anyone having the knowledge to muddle their way through it all and make it actually fly, yet they do.
All of this junk has been added to our airplanes to make them better and safer. What it all boils down to is us having a bunch of tools that we get to use when and if we need them. We really do not
need hardly any of them, in order to fly.
I was on a long flight a few weeks ago, my instructor was driving, while I played with my new GPS. We usually flip to see who gets us there and who gets us back.
Anyway, After a while, I started getting bored, I couldn't find anything new or interesting on my GPS, so I started looking around my spartan 30 year old Warrior control panel. I said to Bob, we need more stuff to fiddle with, this plane doesn't have enough lights and switches and things.
He thought that was kinda funny, but he still did not offer to let me drive.
A hand held radio is just another tool. It's a lot like the drill press sitting out in your garage. You hardly ever need it or use it, but when you do need it, you
really need it.
