Fly

“You are going to be the pilot today.” Mike deadpanned.

This is no simulator.

“OK… I’ve taken the ground school, you know.” I said matter-of-factedly, pretending to not notice his attempt at humor.

After ascertaining when and where I took the ground school (where one learns all the theoretical knowledge of flying without taking to the sky), Mike was apparently not reassured. It had been so many years that the answer caused me more pain and consternation because it dated me as that much older than him than because the course material must have been outdated by now, or that I might have forgotten most of it already. I volunteered that my then girlfriend, now wife, forbade me from going any further than that. And I regretted it immediately. By this time he must have formed a pretty determinedly negative opinion of me, having no balls in addition to no sense of humor. Fortunately I was not on a charm mission to please him.

I was at Island Aviation because of a gift certificate for my birthday from my sisters, and because after this many years my wife had decided she could stomach the idea of my taking a small-airplane flight now. And she was there to see me do it. Among her questions was “how high are you going to fly?” “A couple of thousand feet.” Mike, my instructor of the day, answered her directly. But I knew her better. “Actually height is our friend. It’s the ground that’s dangerous.” She seemed to understand, so I gave no explanation.

Mike had gone through the preflight check already, he told me. But he went around the airplane with me and asked me about the different control surfaces. I did all right with ailerons and flaps, and even elevators, but not so well with the rudder. Those damned years! Or maybe I should blame the failing memory due to my age.

Inside the cockpit I was given a brief overview of the instruments. No tests this time. Some instruments look more familiar than others, but the most important ones are all directly recognizable. After all, other than the flight school, I had much experience on the Microsoft Flight Simulator, which I didn’t mention to Mike. It might count negatively. It’s interesting to notice that the instruments were easy to calibrate, but also easy to get out of whack. During his short demonstration, Mike had to repeatedly calibrate the attitude and altitude gauges, as they seemed to be jiggled by mischievous cherubs behind the instrument panel. That I didn’t mind. The less fancifulness, the less likely things could go inexplicably wrong.
Mike pointed out the throttle to me; and I correctly identified the trim wheel. But when I asked him about the radios, he was alarmed. “I’ll take care of the radios,” he said. That was totally cool with me. I didn’t have a clue how to communicate with Air Traffic Control (ATC) any way; nor ground control, for that matter. But I did have my own headset, which brought me an incessant stream of chatter, much more than I imagined possible for a small airport like the Islip/McArthur.

Don’t try to clean your screen–that dirty stuff was on the airplane’s windshield.

One other thing I didn’t get to learn in the flight school or practice on the MS Simulator is the pedals. They control the wheels and brakes while on the ground, and the rudder in the air. Mike let me try to taxi the airplane, which turned out to be very difficult to do—I just couldn’t get it to go along a straight line as I wished, or turn around at will. Fortunately we weren’t on the ground that long.

Taking off was surprisingly easy. Mike pushed the throttle to full, and I waited for the plane to hit 110 knots before pulling up its nose, all the while letting Mike work the pedals to align our Cessna with the runway. Within a couple of seconds, and before I could get used to this new attitude (of the plane), we were lifted off the ground, seemingly swept up by a puff by the big bad wolf. The sensation was definitely not the same as a passenger jet plane, but probably more like a raptor taking flight. With wind pockets hitting our wings at random, we soared upwards along a jittery slope, with my innards going up or down, left or right for no apparent reason. Now I assure you that I can drive a car very straight on the ground; and unlike the pedals, the control yoke didn’t feel hard to handle, so this did not reflect my abilities. I looked to my right. Mike was a model of nonchalant and unconcern; which could only mean one thing—I just had to get used to this sensation. In a few minutes we reached our cruising altitude, 2000 feet, for this part of the flight. Mike helped me to set the trim, and the plane could practically fly itself—only I was more comfortable clutching the yoke tightly in my hands.

Once we got over the coast, right about Heckscher State Park, we were out of ATC zone. Mike told me to turn to the east. I execute a mild bank, and he asked me to put a little “back pressure” on the yoke, to maintain altitude—strictly speaking, it’s probably more like we executed the turn, as I was working the yoke only, and didn’t even think about the pedals. (Having no pedals for the MS Simulator, I always left it in its “auto-rudder” mode. And coordinating the rudder with the yoke to make a turn is akin to driving a manual shift car.) Coming out of the turn, I tried to reach my camera on the back seat, and found it nearly impossible. The cabin being that much smaller than the inside of a Geo Metro, (and the plane probably lighter than the Metro too) I had to lean my upper body way forward so that my right arm can swing around without hitting Mike’s face with my elbow.

Along the coast we went, looking over Long Island and Fire Island below us. Some of the signature places I was able to recognize, but far fewer than what Mike could. Most importantly, he pointed out the various airports. In an emergency, we’d have to pick the nearest airport to land, I secretly tell myself. We went as far as Riverhead before turning up north and then back west along the north coast of Long Island, carefully flying around the airspace of Calverton airport, where sky divers might be dropping down from above our altitude. I executed smooth and wide turns, a smooth ascend to 3000 feet, and a smooth descend to 1000. I’m just not a dare devil. Not only I didn’t have the desire for steep banks or dives, my guts wouldn’t have taken it nicely either.P1070126

Before heading back to the Islip airport, Mike wanted me to fly over our house. But when I got to within about 5 miles, he realized that we were about to enter the ATC zone. He took over the controls, wheeled us around in tight loops, while talking with Islip control tower on the radio. I felt uncomfortable, and Mike saw it. I told him I was a little air sick. The air traffic controller sent us in via a flight path that was to the east of our house, but eventually passed over my work place.

When we were coming down to land, I again wasn’t aggressive enough on pushing the yoke forward, and had to be reminded where we’d like to hit the runway. Mike took over the controls when we got closer to the ground, as the wind tugged more strongly on our airplane. Flaps down, nose up, we let the plane kiss the runway where it wanted. It felt so good to be on the ground at last.

In the end, although I didn’t enjoy the experience completely, I was glad that I had the opportunity. Maybe flying was never in me, but I wouldn’t have known it beforehand. It’s very different from driving. Also prone to car-sickness, I almost never felt sick driving a car. When I am in the driver’s seat, I try to be gentle on the gas and brake pedals, and road is predictable, exactly in the way the air is not. I don’t know whether I could have overcome air-sickness if I persisted. But at this stage of my life, there are many other things that call for my time and energy. There is no regret giving up flying.

I am grateful to my sisters and my wife for giving me this opportunity. And I am grateful for this country—not only there was no concept of general aviation at the time when I left China, I don’t think it is an option even today. You learn to fly if and only if that is your job. But here, I fly because I want to. And that is priceless.

A letter to United Airlines CEO

Jeffrey A. Smisek
President and CEO
United Airlines
77 West Wacker Drive
Chicago, IL 60601

Dear Mr. Smisek,

Last Tuesday, August 15, I was scheduled to travel from O’Hare to LaGuardia on United flight 696. Eventually the flight was cancelled after several delays, and the alternative flight I was able to fly on, flight 694, was found to have an equipment problem, and we had to switch to another aircraft, incurring further delays.

I do not blame the airline for the weather and ATC related delays that befell flight 696, or the equipment problems related to flight 694. I do not even begrudge United for the three round trips I made between Concourses B and C trying to get alternate flights. However, I noticed many areas where United Airlines employees could have exercised greater compassion towards their passengers and better professionalism. Or at least, United could improve its processes significantly, if it couldn’t trust its employees taking the most appropriate initiatives in critical moments.

  1. When flight 696 was cancelled, there was no announcement at the gate that it was assigned (I forgot the exact gate number but this was on Concourse C, and different from the original gate due to the delays). Instead, the gate signage inexplicably started to show that the gate was to process a different flight. The cancellation was only listed on the departure notification screens. The next available flight for LaGuardia was over on Concourse B.

    Flight cancellation is a business decision on the part of the airline, but it is a disaster for its passengers. United should not simply announce the cancellation on the flight schedule boards. Instead, the first line of business after the decision had been made should be to reach out to its affected customers as quickly as possible and offer relief.

    I think a much more appropriate process calls for at least one verbal announcement over the PA system near the gate, and clear instruction that the passengers affected could get their rearrangements made either at the same gate, or at a nearby gate. Extra gate agents assigned to the task would have been welcome—after all, O’Hare is a United hub and there is no reason that it couldn’t mobilize some more resources for the task.

  2. When many of the passengers from the cancelled flight 696 reached gate B9 for rebooking on flight 694, they were left standing in line for more than 30 minutes, with none of them being processed in the mean time. At the beginning there were three United associates at the counter. Eventually two of them left, and the only one on duty left word with one person at the front of the line that he would not be able to process the change requests until the Pittsburgh flight, which was to start boarding soon, was sent off.

    Even though people standing in line may not be a planned event, it should be treated by the airline like a fire that needs to be put off. I don’t know why the two female employees left the counter without processing any of the people in line, or why the sole male employee who was left behind couldn’t process some of us before the boarding process for the Pittsburgh flight began, but mostly, I don’t understand why there was never a call for backups, for some additional gate agents to help out with the situation. Clearly, the airline and its gate agents did not care enough about their customers’ physical fatigue and mental anguish caused by the delays in processing their alternative flights.

  3. Our alternative gate for flight 694 was B19, and we were let to believe that we could just get over and board a plane available there already. We hurried over and waited in line, for another 30 minutes. It was after 20 some minutes that there was an announcement that we couldn’t board because they were waiting for the flight crew. Why was there no announcement at any time that people didn’t have to wait in line, but would be called in due time by boarding groups?
  4. On Thursday (August 16), I got an email from United saying that due to delay or cancellation, I was now scheduled to fly on United 3484, scheduled for Friday August 17 at 10:00 AM, from O’Hare to LaGuardia. I understand that this was due to some clerical error, such that United had not realized that I had reached my destination already. But…

    If a passenger of yours were delayed by more than 36 hours, should s/he be reached through email? Shouldn’t some customer service person be on the phone already, offering apologies, compensation, in addition to the alternative flight?

In fine, I suggest that United retool its processes in dealing with delays and cancellations, retrain its gate agents to treat each passenger with ultimate respect and compassion, and seize each instance of delay and cancellation, whatever their causes, as an opportunity for providing exceptional customer service.

And when the airline fails to excel at such an opportunity, a little apology and compensation for those gravely inconvenienced could go a long way towards earning some good well from its customers.

Sincerely,

(me)

The Apoptosis of a Color Printer

(Ok, I understand apoptosis is usually not used (or useful) relating to an inanimate object. But bear with me.)

 

By my totally unfounded estimate, our Canon IP2000 Inkjet Printer must have died some two years ago. This is not an anniversary or any other special date, but I thought if I don’t write something down now, I’d never do it.

No, the printer was not that special to me that I’d treat it like a pet or something. It did print brilliant pictures, as brilliant as some good inkjets other people had did, especially when we gave it good inkjet paper. And it did not misbehave more frequently than printers of similar birth and persuasion. What made it special is the way it died, suddenly, unexpectedly, with a lot of good paper waiting for it because of the untimeliness of its demise.

That day was nothing particular; not warmer or colder than usual to be remarkable, and no storms of any kind like the Chinese would like to believe that a day would be if it were to herald something significant. All I remember was that the printer refused to print after a few good nights’ sleep. It simply blinked one of its lights in a mysterious sequence, and sat there quietly.

We looked up the User’s Manual, which was never consulted with unless we, or the printer, was in trouble. It did not clear up the matter much. The mystery only deepened, as the particular explanation for that sequence of blinks is that the print head is not installed, or installed incorrectly. Now I am not confident that I can tell the print head from the print tale, but no interior parts of the printer was touched between this moment and the last time the printer printed something.

Eventually I was able to find the Service Manual of the printer on the internet (it does not come with the printer). This was not something I could download, but only to view on the website. (I did show it to my son, so at least there was one witness. A minor, though.) This document cleared up things a lot better. In it, it is stated that the same sequence of blinks can also signify, can you guess it… the end of the printer’s life.

Now this printer was not used a whole lot, as we have had a laser printer all along, longer than the inkjet. And most of our printings were of text, which the laser printer reproduced with much better clarity and endurance. But this Canon printer’s life is calculated based on a number of pages or a number of days, whichever comes first!

I felt betrayed. This is madness! They planned the printer’s death before it was sold, and never bothered to tell those who bought it! Then I felt bewildered. If the printer’s like the razor and the ink and paper are like the blades, isn’t it to the manufacturer’s advantage to let it live as long as it could? Then I felt disgusted. I don’t want to keep the product of such an evil manufacturer in my house any more! We dropped it off at Best Buy, where they have an electronics recycling program.

Soon we bought a color laser printer, of a different brand, and forgot about this Canon.

 

But now I realized, I cannot simply forget. At least not until I’ve written about it, told some people, and maybe asked them to share its story with even more people. Then, there is a chance that we can help others to avoid the feeling of betrayal, bewilderment or disgust its brethrens might bring. And that would be a lasting legacy that’s worthy of this printer of mine!

Now let’s get back to the title. Apoptosis is the mechanism through which an organism refreshes itself. Instead of living with aged and damaged cells, the organism lets the old and damaged cells die, and generate brand new ones in their place. The peaceful death of some cells prolongs the survival of the organism.

In the case of our Canon printer, the apoptosis is not in the sense that certain parts of it died for the good of the whole printer. No, it’s the death of one printer for the betterment of a much bigger organization, the Canon Corporation. They have decided secretly that the printer should die some time after it was bought, while as buyers we had fully expected that the printer would last its “natural” life, and nobody ever bothered to tell us otherwise! Do they understand that even though I bought a Canon printer, my action did not mean I support the survival of the Company?

That was the last Canon printer I bought. Hopefully, whoever is reading this, you’ll not buy one in the future either.

[While I cannot find the “Service Manual” any more, I was able to find a “Simplified Service Manual” on the internet. And below is a section from it.]

Overcrowded train in India

The world population is to hit 7 Billion around Oct. 31, which is a couple of weeks away. In particular, India is rapidly catching up with China, to become the most popular country in the world around 2030.

Yet in some parts of India, the Catholic church is encourage people to have more children! See http://www.msnbc.msn.com/id/44856793. Of course, use of condoms is also against Catholic teachings. Would somebody please wake up his Holy See?

Nuclear Power Plant’s Plan B Can Be Improved

I’m no nuclear scientist, and it is probably too early to have definitive information for what went wrong at Fukushima Dai-ichi nuclear power plant. From armchair guesstimation, I came up with this possible series of events that led us to the current state of affairs:

  1. The earthquake near Sendai disrupted the power grid in the Northeast region of Japan.
  2. The power generators automatically shut down for self-protection (they don’t want to generate power and keep it!).
  3. The nuclear generators automatically shut down, also for self-protection (the heat they generate was no longer needed by the turbines). This stopped the controlled chain reaction, but the radioactive fuel still generated some heat due to spontaneous radioactive decay.
  4. The back-up (diesel) generators started automatically, to keep the reactors cool.
  5. When the tsunami came, it knocked out the diesel generators.
  6. At this point, the backup batteries were pressed into service.
  7. About an hour later, the backup batteries were exhausted, and there were no more levels of backup.

Maybe Plan B often works out badly, causing the disasters we get to know. But they don’t have to.

In this case, it is apparent that the secondary backup system was started correctly, and the tertiary backup system was not destroyed or damaged, but rather run through its designed cycle. The problem is that the tertiary system was never designed to last many days while the primary and secondary systems were out of commission. (It’s also possible that the batteries were not even designed to power the cooling system.)

And why did the secondary system fail? After all, it was designed to run independently, without external resources, and it is apparent that the reactor buildings were not damaged by either the earthquake or tsunami. Here I venture a hypothesis. It failed because it did require an external resource after all, albeit one that was generally ubiquitous and plentiful.

You see, diesel is fossil fuel, and a diesel engine cannot run without air. And in a tsunami, the air intake would be inundated, smothering the engine. Furthermore, the seawater and debris would cause long term damage to the air intake and outlet systems.

This leads to the obvious solution: why don’t we design a completely independent and enclosed backup power generator system to run the cooling system? We can use the radioactive decay heat to run a small generator, which runs either a secondary cooling system or the main cooling system at a reduced level. This would not require any external resources, not even air, and therefore can be completely enclosed (a friend of mine relates the design to the generator in a nuclear-powered submarine). The only point where this system would fail is where there is no enough heat to run the generator, but the point is also one that relieves the necessity to run the secondary cooling system!

(Admittedly there is another possible failure mechanism for this design: if the surrounding environment is too hot—its definition depends in turn on the design of the cooling system—the backup turbine might not run, or the cooling system might not remove enough heat from the reactor. But if that happens, we have a much bigger problem on our hand than a runaway nuclear power plant.)

Hello world!

I haven’t been blogging for a while now. In the mean time, I read somewhere that Microsoft was closing shop on their blog site, and I was quite irritated. Why would they not send a nice email to the bloggers on their site (or at least me), instead of letting them find out from a news article? What if they didn’t read the news for a day or two?

This is my first post on WordPress.com. Funny that Microsoft kindly arranged to have my account “migrated” to a different site instead of trying to compete harder, instead of leaving me out to find a new home by myself. So far this site seems to be nicer than live.com. No wonder Microsoft can’t compete.

While I’m kind of grateful that Microsoft thought of a way for me to go on blogging, and that the new site turned out kind of OK, I’m not completely happy about it. For you see, for some reason, Microsoft’s live.com is just about the only site that is reachable from within the Great Firewall of China. Not Google’s blogspot.com, nor this site. Maybe Chinese government didn’t realize that live.com has a blog site! It was very small, after all! That must be it!

I also wonder what WordPress.com has done to deserve the ire of the Chinese government (I know what Google did, and I have mixed feelings about that). Maybe some careless blogger inadvertently mentioned some dissidents, like Liu Xiaobo? But wait, without Chinese government’s contribution, he would never have gotten the recognition that he did, such as winning the Nobel Peace Prize. I’m deeply puzzled.

Peace.
