This could be more easy than you might think for today's slaves to technology. Fight plans are uploaded on to the airplane's flight management system (FMS) by ACARS which is sort of like/WIFI. In my day we took pieces of paper and both pilots would load the flight plans, weather data and a bunch of other into their independent systems. Then we would go through a ritual of comparing what I had on my screen to what my 1st officer had on his/her screen. How yesterday. Just upload the flight plan, takeoff, throw on the autopilot, don't pay attention, (why bother you, haven't so far) and the airplane will fly to Edinburgh if that's what the flight plan says. Waite until we get self-driving cars.
Dude, you are still talking about "screens"!!!! That ain't very "yesterday". My "yesterday" consisted of no autopilots and no flight directors...and no screens!!! I say that somewhat tongue and cheek. You likely have more experience on older stuff than I do.
But...if yo are really interested and how we plan a flight these days:
Yes, we have an app on an iPad called "Pilot Mobile". Our flight plan and weather package is pushed to the iPad based on our schedule. You tap it...the flight plan comes in....then look at the weather....then electronically sign the release. You then download the entire flight plan and weather package along with the Maintenance items related to that aircraft because, of course, we have an electronic logbook...which is wonderful!!!
We go to another app....WSI....a vendor....and it is friggin' amazing the stuff you can get off of there...with an overlay of your route and any layer you want including vertical profiles as it relates to weather and turbulence.
Yet another app....Jepp FD Pro is where all of our charts are. Search your flight number and bam, all of your related charts are right there.
I will take offense to your "turn on the autopilot and don't pay attention" remark. Flying has never been safer and you know that. The reason why that is is because of many things...but technology is right at the top. Not necessarily the technology of the flight control systems but the technology involved in the entire "Safety Management System". Google it if you are not familiar. (Airline)Pilots today have so much information at their fingertips and at the tip of the spear when it comes to human performance. Human Performance in the good ole days was simply "Don't f*ck up!". And if you do, don't tell anyone. And if they come after you, blame everybody and point fingers at everyone but yourself. And the company would sell you out to protect their own ass. IOW, there was not a lot of sharing of information and therefore unsafe trends would continue and would fester to the point of causing accidents.
I could literally write a book on why airline flying is so much safer now than it was 20-30 years ago. But I will spare you...
