Doug overstates the case a bit. Even without elevator
control it is possible to damp out the phugoid mode.
I tried this on a BFR recently and I encourage the
rest of you to give it a try as well. Since the phugoid
is a function of airspeed/pitching moment coupling,
you can damp it out by applying speedbrakes at the
bottom of the cycle. This take a bit of thinking ahead,
but it can be managed with practice.

The United 232 crew was able to control pitch through
pitch/thrust coupling. They applied collective thrust
to adjust pitch and differential thrust for directional
control. It was crude put effective enough to get to
the runway threshold. Unfortunately, the dug s wing
in on landing. It was not directly a result of the
phugoid mode, though I suspect all the different modes
conspired a bit.

Yes, according to Peter Garrison's 'Aftermath' column
in the November
issue of 'Flying' you don't need to connect your elevator
control! I
quote: 'the NTSB report does not comment on the fact
that a
disconnected elevator does not make an ASW-20, or
for that matter any
other airplane, unflyable. The situation is aerodynamically
no
different from what occurs when the pilot removes
his hand from the
stick.'

I think I'll start leaving the elevators off my ASW-15
now. Imagine
how the reduction in drag will improve the performance!
Not having to
worry about pitch control will certainly cut down
on the cockpit
workload as well. The benefits are endless!

Well, it may be flyable, but not landable! The stick
free phugoid can
get pretty dramatic, even with the mass and friction
of the stick
attached to provide some damping . If you have not
tried this, you
should. Keep hands completely off and keep the wings
level with
rudder. Let the phugoid fully develop--it's a real
roller coaster
ride. Close to the ground, it's a crap shoot whether
you would land or
crash.

There was an accident a few years back in a DG-800
that had a loose
nut on the elevator control. The pilot hit on the down
part of the
phugoid and crashed wings level. He lived, but never
flew again.

The same thing happened to United Flight 232, the DC-10-10,
that
crashed while attempting an emergency landing at the
Sioux City
Gateway Airport, Iowa, in 1989. After losing all hydraulics,
they had
no movable flight controls. They were able to fly the
aircraft with
differential thrust on the two wing engines, but they
could not
control pitch on final approach.

I have not seen the article, but I'm surprised that
a knowledgable
person would suggest that elevator control is optional.
