AI Thread Summary
Swapping out WWI era magnetos in lightweight small airplanes for modern fuel injection systems could potentially achieve fuel efficiency of 100 mpg. The discussion highlights the impressive accomplishments of Steve Fossett in Rutan's world-circling plane, emphasizing innovation in aviation. Despite the clear benefits, the slow adoption of electronic fuel injection (EFI) by engine manufacturers raises questions about cost and practicality for general aviation pilots. Additionally, turbocharged diesel engines are noted for their ability to provide greater power during climbs and improved efficiency at altitude. Overall, advancements in engine technology could significantly enhance aviation performance and fuel economy.

What did Steve Fosset accomplish in Rutan's world-circling plane?
 
I read that article when it came out. Quite impressive!

With expense being a big issue for most general aviation pilots, one has to wonder why engine manufacturers didn't adopt the EFI/http://en.wikipedia.org/wiki/FADEC" approach years ago.

Better still, turbocharged diesels show even more promise in terms of greater power throughout the climb and on hot, high-altitude takeoffs, while delivering better efficiency for any given velocity at altitude.

Thread 'Never think never for an improbable event'

Pilot training is critical to safe flying. I watched the following video regarding the crash of TAM 402 (31 October 1996), which crashed into a Sao Paolo neighorbood about 25 seconds after takeoff. https://en.wikipedia.org/wiki/TAM_Transportes_A%C3%A9reos_Regionais_Flight_402 The pilots were never trained to handle such an event (the airline had asked the manufacturer about training for this event), since it was considered too improbable (so rare) by the manufacturer. There was no...

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
