How does engine compression ratios affect performance
Higher ratio increase efficiency
Characteristics of heavy aircraft
More momentum Require powered controls Large weight carrying capacity Larger c of g range Longer wheelbase
Why is jet aircraft faster
- Swept wings
- Low drag at altitude
- Poor lift at low speeds
- Spoilers
- Higher approach and ground speeds
- Fly better in severe weather
