there is no reason for you to have a fugoid.
when you pull off throttle the aircraft simulataneously slows slightly
and enters a glide decent. I've never encountered any phugoid tendency
in that manouver.

I know of one instance where this occurred in real life.
a couple of years ago there was a charter flight out of perth in a
pressurised twin. there was some pressurisation problem and the pilot
wasnt quick enough getting to the mask to stay concious. the end
result was that the aircraft climbed way above unpressurised breathing
altitude and all on board died. the aircraft crossed australia until
somewhere in queensland it ran out of fuel. the aircraft was being
tracked by others and the report is that the aircraft entered a gentle
glide decent and was destroyed in the impact.
there was no report of instability during the last part of the flight.

Any phugoid in pitch and the time line of that Phugoid will be directly
associated with the dynamic stability of that specific aircraft in pitch.

It all depends on the specific aircraft.

Whenever I see the word "phugoid" I think UA 232.

Al Haynes and company. What a magnificent job of flying those guys
pulled off that day. Haynes is one of the TRUE professionals in the
business. And the guys with him that afternoon were no slouches either.

I once had a former chief engineer with Burroughs demonstrate phugoid
oscillation to me by grasping a book by the top in one hand and the
bottom in the other, holding it horizontally, and tossing it into the
air so that it spun on its long axis. Behold, the top and bottom
sides of the book swapped places in mid air.
