A good real life simulator for airliners would take into account what’s current policy of airline companies and aircraft manufacturers. Passenger travel should be energy-optimized and have lower emissions.
Companies adhere to rules (the law) and have acknowledged the issue with emissions. Regulations start coming up in Europe, imposing higher cost. The industry is working to comply. Pilots are…
What if MSFS2020 would take some of these factors into account ? Is there a panel instrument indicating fuel usage per nautic mile distance ? somewhere maybe… is it readable ? is it used ? there is no activity dependent on fuel usage per nautic mile, so… why bother.
Suppose there would be a 747 (or Dreamliner, Neo) Challenge activity, you win if you keep total fuel use per passenger as low as possible, to get passengers from A to B. You would choose to fly the most energy-effective aircraft, impose restrictions on luggage weight… fuel initial load… and you’d choose a smart takeoff procedure and flight route, using the engines in an optimal way. Wind could play a role… There would be instruments on the cockpit panel to do an energy-smart takeoff.
