Another Cirrus 'chute deployment

C,

You continue to say this even though the manual does not. The manual
actually prohibits attempts at normal recovery and requires immediate
deployment of the BRS.


You're right (how's that?!). I apparently had access to an outdated
manual, which said differently.

Also he was close on the operation limits and if he was heavy (overloaded)
he could have easily gone in a stall/spin including heavy turbulence

Why? He was (as has been pointed out in other posts in this thread) almost 3
miles AGL. If he was losing airspeed, point the nose down. Why would he
stall? I've been in a lot of turbulence (I live on the Colorado Front Range)
and it has never caused the airplane to come close to stall speed.

Well, I can't claim to have ever flown in severe turbulence, but my
sense is not that the turbulence causes you to lose airspeed and stall,
but that the correct way to handle this situation is to slow down enough
that you are likely to stall if a gust is severe enough to stress the
airframe. That's not to suggest that you want to end up in a spin, but
it seems preferable to stall and spin at altitude then to have parts of
the plane get ripped off. If I'm in a thunderstorm I'm going to make
sure my airspeed stays below Va.

exactly you're in a climb for some reason and heavy turbulence hits - woops
late response wrong rudder input you could do it.. not likely but i've flown
and climbing at vx or even vy and you hit a gust, stall alarm goes and if
you are THAT high - on a hot day you could get in a stall

(I think anyway)

C,

Sounds an awful lot like "won't recover from a spin and has never
demonstrated recovery from a spin" to me.


Well, that's a world apart from your earlier categorical statement.
Elegant retreat, though.

Javier,

B) It's being spun again for certification overseas.


Where? In Europe, it is now certified with the chute.

C,

Who says I am anti-Cirrus?

ROFL.

The Cirrus manual says the airplane cannot
recover from a spin except by deploying CAPS.


Again: It does in NO WAY say that.

"Spins
The SR22 is not approved for spins, and has not been tested or
certified
for spin recovery characteristics. The only approved and demonstrated
method
of spin recovery is activation of the Cirrus Airframe Parachute System
(See
CAPS Deployment, this section). Because of this, if the aircraft "departs
controlled flight," the CAPS must be deployed."

I figure that's like saying "The maximum demonstrated crosswind is 17 knots.
Because if this, you must not land in crosswinds of greater than 17 knots".

Ok, there's the "must not" bit and the "approved bit" but saying "Don't do
it"
is not the same as saying it can't be done.

There's been a big debate about the spin characteristics of my plane,
the Scottish Aviation Bulldog. It can get into a mode where it is very
difficult to recover using "normal" or "recommended" techniques. It
was found by one of the former British aerobatic champions that
giving a blip of throttle made the plane recover from this type of spin
pretty much immediately. A large outcry followed saying this wasn't
approved technique and non-standard recoveries should not be
attempted, etc. The RAF "thou shalt" if the plane got into this mode
of spin was to jetison the canopy and jump out.

OK, well, from the JAA certification testing:

Results. The aircraft recovered within one turn in all cases examined.
Recovery controls were to reduce power, neutralize ailerons, apply
full rudder opposite to spin, and to apply immediate full forward
(nose down) pitch control. Altitude loss from spin entry to recovery
ranged from 1,200 to 1,800 feet. Detail results can be found in the
above referenced reports.

The "above referenced report" is a largish pdf file you can download
from, among other places, the COPA website.
