What are the pros and cons of a straight wing plane? I need this asap for my folio... Much appreciated. I'm doing a research section on my folio and I need to know the pros and cons for a straight wing in general. Everywhere I've searched doesn't seem to have the question above and is making it very difficult.
I assume you mean unswept vs swept-back wings.

Pro:


Easy to manufacture
More efficient at low-subsonic speeds


Con:


Unstable at transsonic and supersonic speeds (see Mach tuck)


More details about wing sweep (including forward sweep) that should answer your question: Swept wing
