Paul is right, good practice for when the electrics go out.

I learned to fly in a Schwitzer 2-32 glider.  Spoilers are used to control
rate of decent and sometimes they are not enough. Slips are required at
times,  plus slips are just plain FUN. BTHW I would like to use slips more
often in a C150, but they are not approved with full flaps. Most of the

time

I use full flaps, so no slips most of the time.

Do it anyway Monty at altitude so you can become familiar with how it
behaves. The 172 bucks a bit more with full flaps than the 182. Never
tried it in a 150.

Check the operating manual first.  The 172 has a no slip restriction when
flaps are deployed.  Also, a member of our EAA chapter was killed in a
breezy several years ago.  He loved to slip airplanes on final.  However the
breezy cannot be slipped.  No buddy knows for sure but a slip might have
been what killed him.  Know your plane's capability or, in the case of
Experimental, test it at a safe altitude.

If your engine is dead and you find yourself still a bit too high
over that foot ball field you choose and some how you still got the flaps
all the way down in your 150 it might be nice to know what it
will do as a slip is your only option left. Screw the operating manual.

It is not going to fall out of the sky.

Okay, guys, you got me interested so I got out my manuals for the 150 and the
152.  I looked everywhere for a prohibition against slips with flaps down.  There
aren't any! No not recommended's either. No listing of placards under limitations.

Myth, legend and rumor don't count.

P.S. I did come across something interesting in the 152 POH about leaning. for
maximum economy the engine is to leaned to peak RPM and continue leaning until RPM
drops 15 to 50 RPM!  Variation is whether you have a Lyc O-235 L2C, N2C, or a
Cont. O-200. Sounds remarkably like lean of peak to me.

Peak RPM would be max power. Well rich of peak EGT.
15 to 50 RPM may still be rich of peak EGT.
