Autonomy, Automation.., oh and Boredom.
Mon, Jul 19 2010 10:48 PM

I have a vision of my automotive future and it is automated.

My family would lease a vehicle large enough for carrying us and whatever we need to take with us. It would take me to work and here's the unusual bit, it would take itself home for whatever my family need of it. It doesn't need to be sat in my employer's parking lot all day. If it needs charging or fuelling, why should I stand guard over it? It can go sort itself out and my contract with whichever fuel provider will take care of the payment. On the odd occasion we need to be in two places at the same time, our lease agreement would ensure a second loan vehicle would appear, driverless, when needed. Servicing, of course, would be provided. Drinking and driving, a thing of the past. Kids need picking up from school? The car can go.

Now this doesn't mean that I want to chase cars from the streets. Far from it, I love cars and driving, but there are better things I could be doing in the time to and from work than avoid crashing in traffic. When I want to go for a drive there are better times to do it than rush hour.

As I understand it most, if not all, of the technology to make this happen already exists. There is, however, a problem of public perception. I mean, cars driving around on their own? What about "sense and avoid"? Won't they just mow down all of the slow moving children, elderly and small furry mammals that cross our streets? Well, actually, I can't imagine it getting distracted, being half asleep or being clamped to a mobile phone (like seemingly half of all the drivers I pass in my new homeland). So why not?

So I was very interested to read David Learmount's post about The lonely airline pilot . As manufacturers like Embraer consider the future of single pilot cockpits and remotely or even optionally piloted aircraft are already with us, what will people think of more automated air travel? Irrespective of the fact that the autopilot already automates large potions of the flight, who would be comfortable if there weren't two people watching it, vigilantly?

To be fair, the idea of being the only person locked into the front of an aircraft for hours at a time doesn't fill me full of the joy of flying. I can't see that it would make for a great recruitment drive. At least with two you can have animated discussions about what's going on in your lives, like, er, the latest crew scheduling. 

How about no pilots at all then? Even though I can see much merit in having a NASA style control room, filled full of the brightest and the best, controlling the aircraft should things ever go wrong, I just have to wonder who it was that held my life in his hands whilst he nipped down the hall to the drinks machine for a quick coffee flavoured beverage and a Kitkat.

First Time Under the Hood
Sun, Jul 11 2010 11:15 PM

A bead of sweat is starting to form on my forehead. It could be the Maryland humidity and we've seen record temperatures recently, but I don't think so. My grip on the yoke is tighter than before. Gone, the sometimes forced relaxed posture in the left seat of the Archer. My eyes, robbed of the what now seems a most generous view of the Maryland countryside, scan furiously in the pattern that I've just been taught. As I make my first turn to meet the VOR radial, my instinct to look into the turn rewards me with only darkness and an unobstructed view of the side panel of the aircraft. At least I now seem to be flying level and the initial gentle porpoising has subsided. 

Going "Under the Hood" is quite literally putting on a visor that obstructs you view of outside the aircraft and to do this so early in my training is a little unusual, so I'm told. In this case the intention was to give my family a flight with few maneuvers, whilst not flying a sightseeing tour that wouldn't progress my learning.

So what is it like? Disorienting, focused, unnatural, but ultimately managable.

The lesson gradually built up my workload. Starting with straight and level flight, then turns without changing altitude. Next find and line up on a VOR radial.

A VOR (VHF omnidirectional radio range) station is a ground based beacon than sends out a signal than identifies 360 spokes around the signal called "radials". You can set which radial you want to follow and a gauge in the aeroplane will tell you if you are flying to or from the VOR and a needle swings to the left or right to guide you back onto the right track when you drift off course. Using both VOR gauges tuned to two different VOR stations and identifying which two VOR radials cross where you are will allow you to fix your position should you be lost.

So, now I am following the radial and continuing my scan of the instruments: artificial horizon, airspeed, artificial horizon, altitude, artificial horizon, heading, artificial horizon. This scan replaces any external reference and it is essential to keep your eyes moving. I found, from time to time, my eyes getting stuck on a gauge transfixed by a value that isn't where it should be. All the time my eyes settled in one place, the numbers on all of the other gauges started to diverge from where I needed them. An unintended turn, a change in altitude, speed dropping off. Small changes, constant scanning.

The last test was a descending, constant airspeed turn to a heading. More workload, more concentration, more numbers to hit. I really enjoyed these games and I will play them until I'm really proficient. I know that ultimately my life will one day depend on playing them well.

Taking My Family Flying
Sun, Jul 4 2010 11:00 AM

Responsibility is something that sneaks up on you as you go through life. I never went looking for it and it snuck up on me while I wasn't looking. Above all else, I am responsible for the financial security of my wife and 2 1/2yr old son and in more subtle ways for their safety, health and happiness. This sits well with me and I am proud to support them.

Being responsible for their safety has never been more in my mind than when doing the walkaround inspection of the Piper Archer before my lesson a couple of weeks ago. As soon as I was finished I invited them aboard the aeroplane and showed them how to strap into the back seats. After sitting him on a booster cushion, I carefully placed an almost comically oversized headset on my son, showed my wife how it worked and then set about the pre-engine start checklist with my instructor.

At this point I had the clearest vision of why I'm so keen to get qualified - to share the experience as much as I can - and it was an opportunity to get them comfortable with flying in a small aircraft. If they don't take to flying then potentially my chances to use this not yet achieved licence will markedly decrease.

Off we went to do the lesson. This wasn't a simple sightseeing flight and my instructor worked me hard doing exercises I haven't done before. All the while my family sat patiently in the back, enjoying the Maryland countryside. We turned for home and once we were back at the T-hangars I had the chance to find out how they got on. "Fine, it was fun", said my wife, though she told me that my son was just on the cusp of having enough of being strapped into his seat as we turned to come home. "Did you have fun?" I asked him as we sat him in the front seat before we pushed the aeroplane back into the hangar. "I want to take off." came the answer. "Well, how about: you do steering while we do pushing?"

 As he happily steered with the control column, we carefully placed the aircraft back in the hangar using the towbar to steer the nosewheel.

So now my son tells me regularly of the time he drove the aeroplane into the garage and asks when we'll go flying with Daddy and Mr Dave (my instructor) in Daddy's airplane. I hate to disappoint the young lad so I'd better get on and get my training done. 

Responsibility means that I will take the greatest care in preparing for flying with my family and I will concentrate on making my skills and experience all they should be when carrying my most precious of passengers.

 I just I won't tell him that I actually only rent the plane.
