Re: [ga] Serious: is there a professional pilot in this GA?

JFC,

I don't think you need to worry about this.

The assistance that (commercial) pilots get are of two types, positioning 
and takeoff/landing.
We don't have to worry about the second one in the case you evaluate, but 
even if, the landing assistance consists of electronic instrumentation that 
translates signals from appropriate equipment (ILS and similar) located at 
runway head, or generally at airports. They basically tell you how off the 
mark you are hor/ver from the ideal landing path, and are effective only in 
the latest part (what is called the "final"), because they assume you are 
already aligned for landing.
The former group are radiogoniometers (VORs or similar) that basically allow 
you to "make the nautical point" and assess your position. The use of this 
equipment is pretty basic flight instruction, necessary to have your licence 
for instrumental flight. In fact, they are not "flying" tools, but 
navigation tools, and they are the same for Jumbos or for small aircrafts 
(in fact, also for boats - the only added dimension in a plane being 
provided by the altimeter).
This with a "caveat": in my days, this was the instrumentation, but I would 
assume that Jumbos nowadays have also a GPS, that will use satellites for 
the same purpose, and that is integrated by software that translates the 
signals received automatically into your positioning.
So, no rocket science, no Internet communication, and the alike.
In fact, the biggest problem that, IMHO, the pilots had to face was to 
become familiar with the "airborneness" of the Jumbo, which is fairly 
different from the Cessnas and Pipers that they were likely to have flown 
before. In other words, the way the aircraft react to flaps, the 
compensation for the turbulence of the landing gear, and so on. In fact, the 
major problem that they had to face was, IMHO, the last maneuver into the 
target, that, unfortunately, they have managed to succeed.
Best regards
Roberto
