The other day, I was watching a very interesting YouTube Video on a significant upgrade in in-cockpit computer hardware avionics communication, navigation, and informational equipment. The feature was by AeroTV and AeroMagazine on the GTN 650 and GTN750. After watching the interview and product review, it occurred to me that others at our Think Tank would be interested in this as well.
You see, we are always talking about computer hardware and aviation safety, especially considering all the major upgrades going on with the FAA's or Federal Aviation Administration's NextGen Air Traffic Control System. In any case, a fellow think tanker, Troy Laclaire, asked a few very important questions about these GTN 650 and GTN 750 systems. Namely; "Why is the screen refresh so slow? Is this due to the amount of information that the unit has to process before fully pulling up the screen?"
Indeed, that is a decent question, and here is my take on it. First, I am not completely sure, but it shouldn't be, perhaps a lot of data loaded, or the software has to switch between functions? If it's collecting information from the satellite in real time aircraft traffic, remember there is at least a half-second to one-second delay. And you can't fix that. For the Jeppesen Data, there shouldn't be a delay.
Next, Troy asks of these avionic units; "If you have a single device that does so many different things, don't you run the risk of pilots putting relying too much on it?"
Yes, I understand that complaint, and yet, remember the old way was to flip through pages in a Jeppesen manual ringed-binder, and fuddle with sectional charts while trying to fly the aircraft. It would be like using the white pages while driving a car to use your cell phone? See that problem, so whereas, this does need to be better, even voice controlled (future mind controlled), it's a way big improvement as it is. But you are right, it's not perfect, and it could be better.
Okay so, all this is an improvement right, but what if these devices fail, asks Troy, while in flight that is?
It's a real issue, then the pilots are back to dead reckoning, hopefully you've been to the airport enough times to know what you are doing already, think of it this way, most people don't look at a map to drive, they know where they are going, multiple ways to get there, and which off-ramps to take based on the time of day and traffic.
Is the unit too hard to use as the pilots must switch from screen to screen, and Troy asks; "doesn't' this somewhat defeat the ability to "scan" the whole cockpit to get all the information you need? In other words, you can't get all your information at once.
Right, so maybe it needs to have "tiles" like the Microsoft or Apple systems, move a tile "Minority Report" way, and tap it once to enlarge? These are all important considerations in in-cockpit computer hardware, and this is some good thinking here, I agree. Still, it's a way big improvement from when I first learned to fly. Indeed, this is like miracle technology considering what I had back in the mid-80s. So, please consider all this.
