Dials or Glass? Your Preference?
For those of us who have been flying for awhile, glass/EFIS is new and can be a bit intimidating... Most new pilots have been playing Microsoft Simulator and are fully familiar with glass cockpits before they step foot in an actual aircraft. Seems like many next generation cockpits require more "monitoring" than actual "flying" (at least after takeoff and before landing).
So, if you had a choice, what would you choose - an all analog aircraft (say a 737-200 or DC-9-30) or a full glass cockpit (say an Airbus A320 or B737-800) and why? Let's assume short-to-medium hall routes. Let's also assume that basic GPS is installed in the analog aircraft. If you fly all-glass, do you get bored at times and wish for more dials and switches?
Old thread that I "voted" on a long time ago, but never posted. Now that I've gone from "Round Dials" to "Glass" and back, and since semperfido revived the thread today, I thought I'd toss in a thought or two.
First, it's apparent to me that the issue of "Round Dials" vs "Glass" is often confused with the issue of automation versus hand-flying. That does a disservice to the original question.
"Round Dials" and "Glass" are both methods of presenting information to the pilot. "Round Dials" require very little, usually NO work on the part of the pilot to present the information they can present, and no amount of work will enhance that information. The exception to this observation, of course, is the navigation information, which depends on the frequency dialed into radio control heads, and sometimes courses and headings "spun" into the individual instruments.
"Glass," on the other hand, requires a bit more work during preflight, usually in the form of typing into a computer keyboard interface. An FMS is the common tool, here, and it should be noted that it is this computer and the information that it presents that distinguishes "Glass" from fancy or modern forms of "Round Dial" instruments. A computer screen that displays "pictures" of round dials, or even other shaped instruments (tapes, lights, whatever) is nothing more than a glorified "Round Dial." It is the collection of various forms of intrument readings and the superimposing of computer-generated information on that basic instrument that constitutes the "Glass" difference. In other words, a computer screen that shows a picture of an RMI is no different than a regular old RMI (which, ironically, usually has a glass cover). However, when you superimpose a radar picture, TCAS traffic, and a line depicting your current flightpath onto that RMI, you have "Glass."
That said, I am a huge fan of "Glass." The situational awareness that is afforded by the prudent use of the tools of glass simply cannot be matched. I believe the work done during preflight to program the FMS is paid off many times over by the superiority of the information that is returned. I've witnessed that one of the most common problems that people learning glass have is not in having too little information, but in finding the information that is most pertinent at the particular moment in time. There's usually MORE than enough information available, and it's convenient, too. It's just a matter of learning where to look and when. I miss my glass!
On the other hand, my preflights are much shorter when I don't have to initialize the FMS. I can do everything in my preflight in the 727 at a very methodical, casual pace, very thoroughly, in much less than 10 minutes. The same can't be said for the Captain's preflight in the MD-11. Programming the FMS for the OAK-SFO leg takes more time than the flight, if you know what I mean.
On the separate issue of hand-flying versus automation... there's an appropriate time for both. When the autopilot can fly the airplane, your attention can turn to other things that might be important - - like traffic at lower altitudes. Use the autopilot too much, though, and your skills begin to suffer. I lke to handfly, whether it's glass or "steam guages," and, believe it or not, the wings don't really care what I'm looking at.
