WWII U.S. NAVY PILOT TRAINING FILM " THE INVERTED SPIN " STEARMAN BIPLANE 87624

I could just imagine myself learning inverted spin recovery - "sorry sir, I can't tell which direction we're turning because my turn indicator is covered in vomit...".🤮

[@joemueller4738]

What’s crazy is now I don’t think they teach new pilots by actually spinning the aircraft,because it’s so dangerous,especially in a twin engine with one engine out. Think too many pilots got killed just practicing spin recovery,.

[@PorkChopJones]

I got it, I got it! Any plane that was in a spin before but not spinning now, has therefore already been spun within the parameters equal to, but not less than the centrifugal force within it's over all deviation of left foot right foot.A procedure better known by it's top secret name, Tipsy topsy turvy! Or I go, you go, we go! Snap; the stick all the way back until you hear a cracking sound,then kick left next, kick right. Now do the hokey pokey, If that doesn't work, say 3 hail Mary's and kiss your butt good bye!!!

Excellent! Thank you!

I learned to fly in a 150 Cessna in the early 80,s. My instructor taught spin recovery. One day we did what I thought was the normal way but found ourselves in an inverted spin. The instructor asked, what did you do? I replied I don,t know. I applied the normal way of recovery which worked just fine. After that we finally figured out how to do it on purpose and did it quite often.Years later I was told that you don,t have to do anything to recover a 150 or 152 but let go of the controls, never tried it tho.

That's clearly an N3N, not a Stearman.

[@tomarmstrong1281]

I have never spun a Stearman, remember they are all old aeroplanes now. But I am familiar with the Walter Extra which spins beautifully, erect or inverted.

[@dwightl5863]

For you pilots out there: How much altitude do you lose in this type of recovery? Lot a variables I'm sure but an educated guess?

[@puremaga17]

if done correctly the acceptable loss of altitude in a inverted spin recovery is approximately 1500' (From the U.S. NAVY PRIMARY FLIGHT TRAINING MANUAL on the N2S) www.stearman-aero.com/media/text/Stearman/Aerobatic_Flying/Stearman%20Aerobatics%20-%20US%20Navy.pdf

@Big Steve Only about 300 ft in a 1 turn spin in a 152.

[@craigwall9536]

I can tell you that with a Great Lakes it takes abut 100 ft if you start with a power-off _flat_ inverted spin. You just come back on the stick and pull some G as you come around so you don't pick up any speed pointing straight down momentarily. Just neutralize the rudder and ailerons and pull; if you were right side up you'd be tucking under- but since you're inverted, it just pops around fast and easy.

A *stabilised* spin, upright or inverted, is actually a stable manoeuvre. Unfortunately, few are taught even the latter these days outside military flight training. Height loss per rotation is low or rate per minute is far less than you'd think once the spin stabilizes and flattens out to a steady rotational rate , depending upon type characteristics. Note I said once *stabilized* in the spin. A spiral dive or incipient spin entry or recovery is not a spin per se. The critical factor is how near the ground you are relative to time/vertical distance to recover, and competent practical IA familiarity and capability with execution of the recovery procedure. You'd never intentionally initiate a spin in proximity to the ground with questionable or insufficient time to recover. Similarly inverted spins. Although the latter can occur inadvertently, IMV&E that's truly unusual or the exception. One really needs to set up and deliberately enter an inverted spin for the most part, and to stabilise it in the types I've executed them in, deliberately hold in pro spin control.

@Art Bell As of 1984 ,no hardly any flight schools in the US teach spin recovery. I worked for a year at flight school and there I learned the reason was that many flight instructors are afraid to do spins themselves which is certainly a disservice to their students.

no thank you.
