Your_Dreamguy: You won't find too much help on Pprune if you decide to "invade" Europe for a civilian pilot job. The US has not be very open about hiring foreign pilots, although I've met a number of them over here. Information and dis-information is quite common on Pprune. But think about the mostly very high tax structure.
The rating conversion might be a very complex and expensive experience. If you are from there it should be much easier.
As for new gizmos, in a "classic" 60's jet, we have no 'T.O.D.' symbol or a 'green banana' .
Automation is the cure?
Sheer coincidence, but in German, the word "Tod" means death. Automation: Cali, Habsheim, Mulhouse, India, Toulouse, the Gulf.
Almost, near Las Vegas.
Always rely on your automation ( the buttons are the Captain). That is what the book says. The book pages shall protect us from cloud-covered granite walls, tranquil white-capped ocean.
One night over water or mountains, the IRS systems, the FMC or the displays might fail. With an APU deferred per MEL then a strange bus tie problem, the equivalent of an "AC crosstie lockout"?
OK-it can not happen.... so stated the 'experts' in the Pentagon.
I can tell you about three near-disasters in four-engine C-130s in which all AC generators were lost for a while. My father suffered two (their lives were twice saved by highly-experienced, very professional Flight Engineers!). An A- an E- and a B-model (over Hawaii) had these frights: all were in nightime IMC. One crew in Hawaii extendd the gear and came thru an undercast. The older C-130s still have no standby ADI! How about the Zantop "Logair" Lockheed Electra over Utah...very bad scene.

To descend, we mostly double the altitude we must lose, then add 10-20 miles, depending upon weight, tailwind and whether we can keep the cabin descending with airfoil anti-ice on, at idle power-easier nowadays with digital pressurization.
But this is the only digital apparatus in the 'classic' airplane, except for fuel gauges. Our two-person c0ckpit requires lots of manual manipulation, having been built before LNAV and VNAV were dreamt of. Plus or minus a good ACARS.
