[From "AFT systems"]
In comparison to a straight wing;
+ Delayed compressibility effects
+ Increase MCRIT, MDRAG RISE
+ Flatter CL curve, so less effected by both speed and AOA changes(less gust sensitivity and reduced CL loss with speed decrease).
+ Less induced drag
+ Better lateral stability
- Tip stalling, (there are plenty of good threads on here about this...)
- Generate less lift
- Reduced CL max and a higher stalling AOA (poor low speed lift)
- Can have too much lateral stability = dutch roll
- HIGH induced drag at high angles of attack (high drag at low speed, i.e. approach)
