Automatic Throttles?

I think after the Asiana Crash in San Francisco we likely will see pilots of all airlines not using automatic throttles when landing as much. The relience of expecting the automatic throttle of staying at 137 miles per hour and the potential lack of communication between the instructor pilot and the actual pilot, combined with the temporary blinding of the pilot by a presently unknown light source (possibly some kind of laser to have that effect at that distance) caused this crash.

So, one of the long term positive effects of this crash will likely be less reliance on automatic throttles, especially when landing.

Automation of all aspects of our lives can be a good thing as well as a bad thing. For example, on a car or truck I like to use cruise control a lot like I do a gas pedal and have become expert at this. Part of the reason I do this is my right foot sometimes gives me problems. So, if I'm on a freeway most of the time I'm using cruise control to a greater or lesser degree. However, most people I know aren't as comfortable with this technology as I am. Even when I first used this technology years ago now I often was scared when I took my foot off the gas pedal and it kept going when I didn't expect the throttle to still be on which might be dangerous in some situations. However, now I have created work arounds so I don't get (surprised in this way). So, it works for me but doesn't work for most other people.

I think the same thing is true of Automatic Throttles when landing in passenger jets. So, especially in pilots who are more novice in that particular aircraft I think you will see they don't use automatic throttles at all in the final stages of landing.
