A Few Random Things

Or why I’m not blogging as regularly as I should.

I’m deep into preparations for my summer-long trip to Washington State and Page, AZ. And it seems that every other week, I’m traveling. And I have two video training courses to record for clients. And I caught a bit of a bug that had me out of action for about a day and a half.

W KeyAnd the W key on my MacBook Pro is not being very responsive.

I’ve also been reading, and when I read, I have less time to write.

Those are just some of the excuses I can offer as to why I’m blogging once or twice a week rather than once or twice a day.

But I’m working on a few blog posts now and hope to release them as they’re finished. Getting started is always the hardest part, so I thought I’d start a few of them at once and let them sit in ecto until I’m ready to finish and publish them.

Let’s see how I do.

TV-B-Gone

A practical joke that may do more good than harm.

I should start out by saying that I’m not a big fan of television. It is the pacifier of the masses. Got a bunch of people liable to complain about a long wait? Put on a TV with something mildly entertaining on it and they’ll sit quietly, hypnotized by the images on the screen. Even if the sound is off! That’s why we see televisions in so many places we’re required to wait, from airport gate areas to doctors’ waiting rooms to restaurants.

My Relationship with the Boob Tube

Keep in mind that I grew up with television. We had one in each bedroom and in the kitchen. We weren’t wealthy people — most of those televisions were black and white — but we were thoroughly hooked into TV. We watched the Today show every morning at breakfast before school and game shows at dinner. I clearly remember seeing first-run episodes of I Dream of Jeannie and Gilligan’s Island. (We weren’t allowed to watch Laugh In — that was for adults.) Every Saturday morning, we were glued to the family TV watching cartoons like Scooby Doo. I remember the birth of Sesame Street and other kids shows like Electric Company. I was introduced to Mr. Roger’s Neighborhood at a neighbor’s house.

I was fifteen when we moved from New Jersey to Long Island, NY, and I got my own room for the first time in my life. Although my sister got a TV almost right away, I didn’t. I got a stereo instead. I got tuned into rock — the real stuff that’s probably considered “classic” now. I clearly remember sitting in my bean bag chair — this was the 70s, you know — near my stereo reading the Lord of the Rings trilogy while a Connecticut-based rock station introduced me to Yes with a 45-minute commercial free segment of Yes music.

I didn’t need a television. With books and good music, I could cook up my own fantasy world right in my head.

I got my own television — a 12″ black and white — right after graduating from college and moving into my first apartment. I was 20.

I got my first color television — a 20-inch Sony — as a Christmas gift when I was in my 30s.

My husband and I now have a 36-inch JVC we bought about five years ago, just before flat screens caught on. At the time, it was the largest television you could buy that wasn’t a projection TV. We bought it to better see the letterbox movies we occasionally rented or watched on various movie channels.

To this day, I’d rather sit in a comfortable chair with a good book than watch the crap that’s on TV. Better yet, I’d rather go out and do something — fly, work in the garden, take a hike, ride a bike, go for a drive, or hang out with friends — than watch TV.

There are exceptions, of course. I really love Jon Stewart on The Daily Show: a dose of reality wrapped in a package of laughter. The Colbert Report is a bit over the top sometimes, but usually worth sitting through. Boston Legal is my favorite fictional show — outrageously funny while clearly making social statements about current events. Other than that, I like informative shows on the Discovery, Science, and History channels, as well as PBS. Shows that can teach me something interesting or make me think.

I watch all television via DVR. For those of you not familiar with the concept — my mom wasn’t — DVR stands for digital video recorder. (TiVo is a DVR device.) It’s build into our satellite TV box and makes it very easy to record the television shows you want to watch. Once recorded, the shows sit on a hard disk and can be easily accessed and watched any time you like — even if the DVR is recording something else. But best of all is the 30-second fast forward button, which makes it easy to skip the commercials.

My TV Problem

I do have a problem, however. If you put me in a room that has a television on and it’s within view, I will get sucked into it. It with grab and hold my attention, turning me into just another one of the TV watching zombies around me.

You know what I mean. You’ve been to restaurants or waiting areas where there’s a TV on. If you’re facing it, you’re watching it. It’s as simple as that.

How can you help it? All those pretty colors flashing about. News channel screen titles and scrolling news tickers grab your attention even with the sound off. You see the pictures, you read the text. Why are the police following that white Blazer? What’s with the yellow tape around that wooded area? Why are they taking that man away in handcuffs? Who’s the guy with [fill-in-the-blank famous celebrity]?

In my case, even if I don’t care about what’s on the screen, I’m still sucked into it. The only solution is to sit with my back to it. But then the person I’m with might be facing it and I can clearly see him or her being sucked in. This makes normal social interaction — like conversation — difficult. It’s as if your party of two or three has just been joined by an invited guest who is demanding the attention of the people in your party.

Think I’m kidding? Exaggerating? The next time you’re in a restaurant or airport gate lounge or other place with a TV on, watch the people around it. How many of them are staring at the image like zombies? How many of them are preferring the onscreen image to conversation with their companion(s)? I’m willing to bet it’s more than 50%.

The universal pacifier.

Enter TV-B-Gone®

I read about TV-B-Gone in Make magazine. It was presented there as a project, but for those of us not comfortable with a soldering iron and circuit board, it was also available for sale.

TV-B-Gone is a universal remote control with just one button: an On/Off button. With it, you can turn virtually any television off (or on).

According to Mitch Altman, inventor of TV-B-Gone:

You can use TV-B-Gone® to control access to television for philosophical or practical reasons, or simply to have fun!

Mr. Altman echos my sentiments about television on the Responsible TV Watching page of his Web site:

How much of the TV that you watch do you really like a lot? If you could choose whatever it is that you’d like to be doing right now, anything at all, what would it be? Was your answer, “Watch TV!”? Whatever your answer was, my wish for you is that you have time in your life to do it. Please make time in your life for what you really like. Better yet, please make time to do what you love. Wouldn’t that be great? Don’t know what you love? Try out a few things, see what happens.

Me, my life got so much better from watching TV less. As a result, I had enough time to invent TV-B-Gone®! My idea was to give others a similar chance – so I created a fun way to get the message out there that turning a TV on or off really is a choice. Anywhere, anytime. Please, go out there and choose.

If you do visit the Responsible TV Watching page, please be sure to check out the links at the bottom of the page. If you’re an avid TV watcher, they may open your eyes to many alternatives.

Anyway, when I read about TV-B-Gone, I had to have one. So I coughed up the $20 plus shipping and bought one.

TV-B-GoneIt looks like the keychain you might have with your car. You know, the kind with buttons to lock and unlock the door and open the trunk. There’s just one button on it and, when you press it once, a flashing red light inside that lets you know its working. Pressing the button twice activates it in stealth mode so the red light doesn’t flash.

You use it by pointing it at the TV and pressing the button. The TV-B-Gone then takes up to 69 seconds to run through all the codes commonly used by television manufacturers to toggle the power. When it gets to the code that activates the TV you’re pointing to, the power goes off (if it was on) or on (if it was off). Pretty simple, no?

Of course, there are some limitations. It won’t work with every television. You have to be line-of-sight with the TV’s remote control receptor thingie. There’s a distance limitation; closer is better. But overall, it’s an effective device for playing practical jokes.

TV-B-Gone in Action!

I took my TV-B-Gone with me on my recent trip to Florida. I wanted to test it out in a variety of settings.

I had no success with the televisions in the gate waiting areas at Houston Airport (IAH). I think it’s because I was too far away. In today’s paranoid world, I didn’t want to be obvious because I didn’t want TSA to come down on me for using a suspicious device. (Perhaps I’m more paranoid than they are?)

I did manage to turn off the TV in the waiting area just before I boarded the plane. It was interesting to see the faces of the people who had been watching it. They went from blank stares to confused stares. Nobody said a word.

A few days later, while having lunch with my parents at a St. Augustine restaurant, I got real satisfaction. We were seated at the counter of the rather small restaurant. There were four — count ’em! — televisions within sight of my seat. One was tuned to some sport channel that appeared to have some kind of log-cutting competition. Another was tuned to CNN. A third was tuned to something else — I couldn’t see it clearly because of the way my seat was angled. And the fourth, a small TV close to the first, was turned off.

I should mention here that no one was watching the two TVs closest to me (log-cutting and CNN). Well, no one other than us, trying to figure out why anyone would compete in a competition that used chainsaws to cut through logs.

I whipped out my TV-B-Gone. A moment later, CNN was turned off. I aimed it at the log-cutting competition. The TV next to it went on. It was apparently some kind of security monitor because it showed images from various locations around the restaurant. In trying again to turn off the log-cutting TV, I turned the security TV back off. That’s when I realized that I probably didn’t have a straight shot to the log-cutting TV.

We continued waiting for our lunch. They were taking their blessed time about it. In all fairness, they were kind of busy.

One of the guys who worked there noticed that the CNN TV was off. He picked up a remote and tried to turn it on. Wrong remote. He tried with another. The TV came back on.

I waited a few minutes and turned it off again.

We’d just gotten our food when the same guy came back and noticed the TV was off again. I clearly heard him say to himself, “What is it with this TV?” He went through the same sequence of trying to turn it on with the wrong remote and then turning it on with the right one. It was tough to keep a straight face. I was seated at the end of the counter and the guy was less than 4 feet from me.

I turned it off again just before we left.

Later, the same day, at Houston Airport, I happened to walk though an area of terminal E that used about 50 televisions to create a display of moving colored lights 15-20 feet over the walkway. How unbelievably wasteful! I activated my TV-B-Gone as I was walking and managed to shut off four of them at once. Later, when I had to walk though the same area because of a gate change, I killed another four on the other side.

Is This a Cruel Joke?

When I bragged in Twitter about turning off the 8 televisions at IAH, @Miraz sent me an @reply message:

Doesn’t turning off TVs annoy the folks watching them? I’d be pretty peeved.

Well, in the case of the 8 TVs with moving colors, I don’t think anyone missed them. They might still be off for all I know.

And my observation of the people in the gate area a few days before didn’t reveal any anger. I think it’s because they weren’t really watching what was on. They were looking at it. Sucked in because there was nothing more interesting (to them) to look at. Or because they have the same TV problem I have.

It’s actually interesting to watch the reactions. It proves, in a way, that they don’t need the television on in front of them. Maybe when the TV goes off, they’ll actually engage in conversation with the people they’re with. Wouldn’t that be special.

But I wouldn’t try my TV-B-Gone in a sports bar. You know the kind of place. They have a bunch of TVs showing whatever real sporting events are on. (I’m not talking about log-cutting here.) Guys are drinking beer and watching the game. They’re shouting at the TV about the plays and the calls. They’re absorbed in what’s going on in front of them.

Get caught turning off one of those TVs, and you’re likely to get a black eye.

And I wouldn’t turn off a TV displaying breaking news about something that really mattered. Or the TV in a doctor’s office if it were displaying content that was keeping kids quiet.

You have to be responsible with your practical jokes.

The Deadman’s Curve

Why helicopter pilots balk when asked to hover at 50 feet.

Last year, I joined a listserve group of professional aerial photographers. These folks, who are based all over the world, have been working at their profession for years. I’m a relative newcomer to the aerial photography scene and arrive as a pilot — not a photographer. (I want to take photos, but it’s tough when my right hand is stuck holding the cyclic during flight.)

I introduced myself and an engaging conversation about flying helicopters ensued. As you can imagine, many of the photographers had worked with helicopters. One of them was even on board during a crash!

One of the photographers in the group told a story about photo flights he’d taken with helicopter flight school instructors. He included this comment:

I was shooting a lot of sailboat races at the time, so where I wanted it turned out to be in a hover at 20 to 50 feet above the water which made some of the instructors nervous. I told them to get over it.

A lot of pilots won’t work in what’s commonly referred to by helicopter pilots as the “deadman’s curve.” All helicopter pilots should know what this is, but here’s a brief explanation for those of you who aren’t familiar with helicopter flight.

The “Deadman’s Curve”

Height-Velocity Diagram for R44 HelicopterThe Height-Velocity diagram in the pilot operating handbook (POH) shows the combinations of airspeed and altitude at which an experienced pilot (or test pilot) should be able to make a safe autorotation in the event of an engine failure.

The diagram shown here is for a Robinson R44 helicopter, but they’re all very similar. The idea is to stay out of the shaded area. Generally speaking, you want either altitude or airspeed — or (preferably) both. Hovering at 20 to 50 feet puts you in the “deadman’s curve” — it’s a combination or airspeed (0 knots) and altitude (20 to 50 feet) at which a safe autorotation is not possible. So if the engine quits, you’re dead.

The height velocity diagram also clearly shows the recommended take-off profile. When a pilot does a “by the book” take-off, this is what he’s doing: picking up into a hover less than 10 feet off the ground and accelerating through 45 knots. Then pitch up slightly and climb out at 60 knots. (You can get an idea of this in my “Shadow Takeoff” video.) Doing a “straight up” take-off like you see in the movies or on television puts the helicopter smack dab in the middle of the deadman’s curve until he’s moving faster than 50 knots or has climbed several hundred feet.

Wondering how the chart is created? With test pilots and helicopters. If you take the Robinson Factory Safety Course, you’ll see videos of the flights they used to build the chart — including one flight that demonstrated what happens when you attempt an autorotation while inside the deadman’s curve.

My Experience with the Deadman’s Curve

I get some photo gigs because I’m willing to operate in certain areas of the deadman’s curve to meet my client’s needs. I’m a single pilot operator so I’m responsible for myself. Other organizations are responsible for their pilots and tell their pilots not to do anything that could be “unsafe.” This is often the situation at flight schools that do photo flights for extra revenue. Those pilots are usually the school’s CFIs, sometimes with only a few hundred hours of flight time. The school makes a rule — no operations under 300 feet — and all the pilots are required to comply.

Operating in the deadman’s curve requires that you have a lot of confidence in your engine and mechanic. The engine failure statistics on Robinson helicopters show that the engine — a Lycoming, after all — is very reliable. And I take meticulous care of my aircraft with two experienced mechanics to do the work. I’m confident in my aircraft. So I take the risk and I get the job.

But I do warn my passengers of the risks inherent in that type of flying. And If a maneuver puts me too close to obstacles or requires me to do something I think is beyond my skill level, I won’t do it. (I don’t have a death wish.)

Get Over It?

“Get over it,” is a pretty funny thing to say to a pilot when requesting (or demanding) that he perform a maneuver he’s not comfortable with or authorized to do.

The pilot who balked at hovering 50 feet off the ground was doing it for safety — his and his client’s. The photographer who told him to “get over it” was unfair to expect the pilot to operate where he was not comfortable. At the same time, the pilot should have clearly stated the limitations of the flight before accepting the job so the photographer wouldn’t expect the pilot to perform maneuvers beyond his normal operating scope.

Unfortunately, more than a few pilots will simply cave in under pressure to please the client. Sometimes this is can be a very bad thing that both the pilot and his client don’t live to regret.

A good pilot will evaluate the risks, make a decision, and stick to it. A pilot who is easily bullied by passengers (or management, for that matter) needs to look for a new career.

Misleading Statements in Popular Fiction

I actually wrote most of this post months ago and mothballed it to finish at a later date. But yesterday, I read something in a novel that made it clear how little the general public understands about helicopter operations.

In the story, the protagonists are passengers on a helicopter that’s running out of fuel. The lead protagonist tells the pilot to lose altitude. His reasoning:

Helicopters sometimes survived engine failures at a few hundred feet. They rarely survived at a few thousand.

The above statement is false. Reverse the facts and you get the correct statement, which I could word like this:

Helicopters rarely survived engine failures at a few hundred feet. They usually survived at a few thousand.

Why the difference? The H-V Diagram is a big part of it. Take a look. If a pilot is flying at 200-300 feet, he’ll have to be moving at at least 50 knots to stay out of the deadman’s curve. The H-V Diagram clearly shows that the higher you are and the faster you go, the farther you are from the deadman’s curve. Altitude and airspeed are two energy management components that can save a pilot’s life in the event of an engine failure.

If you’re operating outside the deadman’s curve, the thing that makes higher altitudes safer is time. If you’re cruising along at 500 feet AGL at 100 knots — a perfectly safe combination of altitude and airspeed, according to the H-V Diagram — you’re going to be on the ground a lot quicker than if you were doing the same speed at 1,500 feet AGL. That’s less time to correct any problems with your autorotation entry, pick a good landing zone, make a Mayday call, brief your passengers, etc. Now imagine cruising at the unlikely altitude of 3,000 feet AGL. In a good gliding helicopter, like my R44 or a Bell LongRanger, you have lots of time to set it up and do it right.

Clearly, higher is better.

There were some other errors in the book as far as the helicopter was concerned, but I’ll save them for another post. (It really does bug me when books, movies, and television send inaccurate messages about how helicopters fly.)

Why Not Get the Facts Straight?

Time passes. I don’t recall when I started writing this post, but I know I didn’t last long with the photographers in that group. They were very full of themselves and highly critical of newcomers. And some of them echoed the same uninformed ideas about the safety of helicopters that I hear everywhere else. Worst of all, they didn’t seem interested in learning the truth.

I wrote a post earlier this month titled “Why Forums Suck” that describes the atmosphere in this particular group. Maybe it’s me, but I simply don’t have patience for people who behave the way some of these guys (and women) did.

And, in case you’re wondering, I e-mailed the author of the book with the errors. I hope he didn’t think I was being rude. But I want him — and anyone else preparing material about helicopters — to get the facts straight before releasing it to the public. In his case, any helicopter pilot could have pointed out the problems I found and reported to him. A few minor changes to the manuscript would have made it accurate without impacting the story one darn bit.

I just wonder if other pilots who read the book were as irked about the errors as I am.

Probably not.
