My ground school handbook for a 172N states on page 52:cyxe wrote:The rear seat is occupied in the spin videos...isn't that a no no for utility category in a 172 ??
Perhaps there some kind of authorization you can get for this a/c to overcome that limitation?Intentional spins are approved in this airplane within certain restricted loadings. Spins with baggage loadings or occupied rear seat(s) are not approved.

hehe good point I didn't even notice that...& yep to my knowledge all 172's have that back seat restrictionNorskman wrote:My ground school handbook for a 172N states on page 52:cyxe wrote:The rear seat is occupied in the spin videos...isn't that a no no for utility category in a 172 ??Perhaps there some kind of authorization you can get for this a/c to overcome that limitation?Intentional spins are approved in this airplane within certain restricted loadings.

Again, from the 172N handbook:bob sacamano wrote:where's capt'sweet'n'juicy now to send this to the authorities. Mind you, the airplane never entered a spin.
So maybe they did, maybe they didn't. I would imagine that they did, since the video is entitled "Harv's Air Pilot Training presents spin training from four camera angles"Application of recovery controls will produce prompt recoveries (within 1/4 turn).

From your last post you said you're still in PPL land. I won't try to teach you on here, but what you saw in that "spin" video is the incipient stage of a spin, that was nowhere near a spin.Norskman wrote:Again, from the 172N handbook:bob sacamano wrote:where's capt'sweet'n'juicy now to send this to the authorities.

Some flight schools also say that once you're done you can fly for air canada, you believe them as well?
From what you quoted and then commented, it seems to me that you missunderstood what the manual was telling you.

The spin constists of 3 stages:
1. Incipient stage
2. Fully developed stage
3. Recovery
The FTM states that the incipient stage can consist of approx. the first 2 turns.
So you are saying that I can enter a spin of up to 2 turns and recover, without actually having done a spin? How can you be in a stage of a spin, without being in the spin?
If I am misunderstanding, I would really like to know.

A stall with Yaw is a spin, doesn't matter how may rotations are involved. The incipient stage is just the first 2 rotations but still a spin.

By the way, to say that 2 rotations is where you get the fully developed stage is wrong, since this varies from one airplane to another.

I am not going into a long disscussion on the aerodynamics of a spin. two rotations is just a approximate number for the A/C to proceed into the fully delevelped stage. If you want the whole briefing I'll have to charge you $65 per hour. 
As for what you said wrong "what you saw in that "spin" video is the incipient stage of a spin, that was nowhere near a spin."
The spin starts as soon as there is a wing drop during a stall.
Read up on a topic before trying to make a educated response on a training forum. The Flight Training Manual will help you achieve a basic knowledge on how an airplane works. You should be able to purchase it at any flight training unit, while your there talk to an instructor and they should be able to explain it in terms you can understand.

Is there a legal definition?Justwannafly wrote:I had a discusion about that with some co-workers this summer & we descided that legaly a spin starts after 180 degree rotation...B4 that its just a wingdropThe spin starts as soon as there is a wing drop during a stall.
Ok lets go with that for a second, How do you recover when the wing drops and rotates you 90 degrees?
If you start the recovery and add power or leave on the power before the rotation stops the yaw from the full power will worsen the rotation, so would you leave/reduce the power off until the dropped wing is levelled? If so this is spin recovery.
I don't/wouldn't mention the term legal to my students when discussing emergency recoveries I don't want them playing with the limits.

Nore do/would I...However we arn't talk'n about teaching spins...just if they enter'd a spin in the video...Personaly I don't know/care BUT all I was saying was that legaly speaking it doesn't start until 180 degree mark. That being said I also said that it was something that we (a group of instructors) descided by looking at various CARs statments....I didn't say that TC agreed with us cuase I don't know...
