I found it had the right amount of information and I didn't find myself being drowned out in information. I used the INS guide to help me learn the CIVA INS navigation system as I had only had minor knowledge of the INS previously. Each manual consists of an in-depth guide to learning the aircraft. Documentation included in the Felis 747-200 includes 4 manuals: Cockpits, Autopilot, INS and Normal Procedures. The installation of the Felis 747 is simple, it is a simple drag and drop into the aircraft folder and the aircraft is ready to fly. I was lucky enough to become a beta tester for this aircraft and I will note that my position in the project has no effect on my opinion of the aircraft. The demand for longer range aircraft with increased payload quickly led to the improved -200, which featured more powerful engines, increased MTOW, and greater range than the -100 thus allowing more passengers to travel and explore further. The 747-200 is a successor to the older 747-100, which was powered by Pratt & Whitney JT9D-3A engines, only offering airlines enough payload and range for medium-haul operations, but this range was marginal for long-haul route sectors. Built in 1968, the 747-200 was a major breakthrough in aviation.
