    Dunno bout that Dennis..... They gotta know how to start the APU and which one is number one and then what sequence to bring up the other 2,or 3. Spool the beach over idle without the other one running and she'll start doing donuts . It would be wise to have time in type.......

    That's a terribly false analogy. Collision/crash avoidance technology is not intended to prevent crashes due to catastrophic mechanical failure.

    They should know how to start an APU if their truck has one ,lol. I can get my Cub to do donuts on landing if I ain't careful.:biggrin_25526:

    To be fair to the pilots, that has to be the narrowest runway in the US.

    From previous threads that discussed the OnGuard system there were forum members noting that calibration of the system is critical for it to function properly, to reduce false positives (falsely noting that a collision is imminent). At a minimum a company deploying a system like that should have well trained technicians and I think that the drivers should be well trained in how to determine whether the system is functioning properly as part of the pre trip inspection. I'm not sure if the latter is possible. Folks with experience with the OnGuard system can chime in here, but my hunch is that there is little that a driver can do to determine whether the system is functioning properly or calibrated correctly. That would likely be something only a technician could do.

    While I mentioned OnGuard in the OP, this thread is more intended to discuss any new technologies and how truckers are using or not using them. The similarity with the airline industry is that fly by wire (or "drive by wire") systems are going to become more common. Recently the Netherlands was reported to be discussing the use of driverless trucks to service their port, for example. The more that "driverless technology" is introduced I'm sure this will lead to additional "driver aids" that will be increasingly taking over driving inputs: turning, braking, applying jakes, acceleration, etc.

    If drivers begin to be lax about their driving habits because they think the automated systems are going to take over in certain situations, there can be catastrophic results. I boldfaced the second part of your post that notes there was a cascade of decisions, any one of which might not be fatal, but when added up resulted in disaster. Usually "accidents" are a result of several decision points that were incorrect, not just one single event.

    Ultimately if you decide to rely on automation to save you, you may end up being "astonished" as the pilot of that ill fated Asiana flight, that the system didn't function the way you thought it should.

    Never thought I'd find use for my aviation knowledge on TTR but...

    Runway 28R at SFO is 200' wide and almost 12000' long. A 777 can (and often does) land on 150' wide runways as many airports especially overseas have narrower (most often 150' wide) runways. The aircraft landed short which has zero to do with runway width. In fact if you look at the ground scarring he was almost on centerline (didn't help in this case). Also your picture doesn't load.

    Lepton1, I'd have to agree with what you say. I am an aviation enthusiast and I do research aviation disasters; and have my share of (non-professional) road time. My first vehicle with (incorrectly functioning) antilock brakes was quite the surprise when I braked hard, then suddenly the brakes released (too long) giving me the feeling of the vehicle jettisoning forward. Front wheel drives change how we are to react to losing the back end of vehicles. I am constantly appalled and angered by bad, discourteous, dangerous drivers who simply do not recognize that they wield the power of life and death while driving. I find your arguments persuasive and logical. Putting all of this together, I'd have to agree that driver training is woefully inadequate, that it needs drastic improvement, and that the different technologies in our vehicles should be included in comprehensive driver's education.

    What a beautiful Cub you got there. That's one airplane that I've always wanted to fly but never got the chance.

    Thank you , I really enjoy this airplane. I am leaving Korea and heading to Indiana on Saturday for a 3 week vacation and will be flying it every chance I get. I have it in a hangar at an airport that has 2 asphalt runways real wide but there is nothing better than landing on a grass runway.
    Hand prop it, hop in and go. No starter just mags. Usually leave the window up and the door down when I fly in warm weather. I am sure you know that I fly from the back seat which is pretty cool and better visibility.
    Praying for 3 weeks of good weather and no crosswinds.:biggrin_25523:

    So I see. I checked the link after posting, must have loaded on my machine from my cache. It was a tongue-in-cheek comment, relative to the photo caption in the lead image here:

    No matter what, the media cannot seem to report any crash-related story that does not contain at least 1 glaring error.
