Default Playing around with the pitch phugoid

Last post-- you raise some good points. It is certainly true that the phugoid may either diverge into increasing highs and lows, or damp out into decreasing highs and lows, depending on the glider and the CG position. I'm a light guy and so my CG is usually well aft, making the dynamics on the lively side. Even if the CG is well forward, I think that some mild forward pressure on the stick at this particular point in the oscillation would help the situation.

Thanks for chiming in.

I guess my mindset is that if that if you can apply whatever forward stick pressure is needed to freeze the airspeed, and then slowly ease the airspeed back to trim, that is always better then simply riding along with the oscillation, regardless of whether the oscillation is going to get more severe, or damp out. Obviously the latter situation is much more user-friendly than the former...
