It went into an unstable phugoid oscillation with each dive being

I did not have spoilers or gear out.


I thought certified aircraft were supposed to demonstrate diminishing
phugoids. No?

In all of the above - "certified glider" appears to apply to a JAR22 - EASA
certified glider.

Don't expect an older "certified" design to have the airbrake efficiency, or
pitch stability. Theory is my Cirrus will stay below Vne at 45%, hands off I
would hate to bet my life on it...

The Cirrus' phugoid amplitude seems to increase rather than decrease at the CG
positions I can achieve. Leave it long enough and it might just get exciting.
Might just be specific to my 35 year old mistress, but I think not.
