Robert,
I suppose you could run out of gas, but I think
the reason for the exercise was to teach the pilot how far the plane would
glide with power off in case he was trying to make a farmers field in a real
emergency.
I think you would be surprised about the
feathered prop. I was trying to change my landing technique the other day
by changing the prop to a coarse setting while in the pattern and locking it in
that setting. I had to give it up because when the plane got into ground
effect, it just glided the entire length of the runway and would not stop
flying! Then when I added power to do a go around, the plane didn’t
want to fly because of the lack of power from the coarse prop.
I was trying this because I didn’t think
I liked the fact that the plane would slow down so fast with the prop in fine
pitch when I pulled the power back. I have now decided that I like it
fine! :>)

Bill,
What you describe is
certainly a possible scenario – actually that sounds like my typical
arrival. With the engine pulled back to 10-12” and a windmilling
prop the decent rate should be similar zero power and a feathered prop.
But how likely is an
engine that fails in the close pattern after a cross-country flight? More
likely something would go afoul enroute, when the pilot could select a landing
spot and arrive 2000 ft above it. If not able to arrive 2000 ft agl –
choose an alternate spot.
Just my couple lira

Robert,
You should try it under conditions that
are more likely to be the case.
Descend to pattern altitude, 1000 ft AGL,
slow to pattern speed, and idle the engine abeam the numbers and see if you can
make it
I recommend you idle the engine and not
kill it, because I would be surprised if you do make it. I also
don’t recommend you coarse pitch the prop since you may need to add power
for the go around.

Bill,
I practiced that
maneuver with a Lancair company pilot flying my ES-P and found it a
non-event.
Overhead upwind at
2000 ft agl and slowing to pattern speed in the turn.
No flaps until over
the fence then deployed everything and aimed for 1/3 down the runway.
I realize the IV
would take different speeds but it should still be do-able with a little
practice.

That seems a scenario where you would be
in better shape with the flaps up. You very well might make the
runway. With flaps down, you likely would not and it would be very
dangerous to try and retract them. With the high wing loading that all
the Lancairs have, they are flying bricks with no power. I think almost
nobody makes the approach to land with no power.
Remember way back in primary training when
the instructor had you remove power abeam the numbers and make the landing
without having to add power? Does anyone practice that maneuver with
their Lancair?
Bill B
Matt, I
agree with the others that w's insults are inexcusable, but I must ask a
question.
What do you do if your low over the
departure end of the runway and the engine quits?
1. Land at high speed flaps up.
2. Lower the flaps and deal
with the big trim and pitch change while making all the other decisions and
actions required in parallel.
