On the topic of spins...
A spin is a stall that is uncoordinated. The easiest way to become uncoordinated if you're purposely entering a spin is to add rudder. This is the *correct* way to enter a spin. It is possible to enter it by just banking the wings, so long as you don't add rudder to stay coordinated, but the bank alone isn't what causes the plane to "break" into a spin.
As for the inverted business, yes, this is what happens during the entry into a spin. Only momentarily, but you do go upside-down. The descent rate in a spin is very high, about 700' per complete revolution in a light airplane, however you're in a stalled condition (one wing anyway...the outside wing is flying, which creates the rotation...), so you're not putting an excessive load on the plane by descending so fast.
Adding power will flatten the spin out, and using opposite ailerons will increase the spin rate, both of which you don't want. There are several great videos on YouTube on the topic of spin training...search for APS Upset training...great stuff!
To recover from a spin, power idle, ailerons neutral, full opposite rudder, push forward "briskly" (one of those keywords the FAA likes so much, especially on checkrides) to break the stall, and then recover from the dive. When you are in a spin, the aircraft is stalled, but is somewhere around 30-45 degrees nose down. Keep in mind pitch attitude and angle of attack are two different things. Pushing forward is a very unnatural thing to do, but keeping back pressure will only keep you in the stall.
DISCLAIMER
Spins (in real airplanes...do it all you want in the sim
) should only be done with a qualified instructor after proper ground training. Don't go out solo and try it just to see what happens. I did spins in a 152 (loaded in the utility category) as part of my training for my flight instructor certificate two years ago. I did them with a former USAF spin instructor with plenty of safety margin in altitude. Rant over.
Enjoy trying them in FS!
