Welcome rurlndum,  (If you would, a name is nice to use for friendliness
- a first name, anyway.)

(I'll let other discuss corrosion detection.  I _will_ strongly
recommend you get a knowledgeable Coupe mechanic who is working for YOU
to do a pre-purchase inspection (preferably an annual inspection) with
no skimping on the corrosion inspection.)


Your experience should serve you well in flying a Coupe.  My PP lessons
were in a 152 and mostly in a 172.  When I got my license and bought my
Coupe, the instructor told me to just go fly it.  I could and did but I
DID study hard, everything written about Coupes and that stood me in
good stead.

We recommend you find a Coupe skilled CFI or a very experienced (or
smart) Coupe owner and get transition time.  There ARE differences in
how you approach certain things.

For example, you ask about the Coupe's famous piano-like glide.  Yeah,
if you glide at a speed near the stall, the sink rate is in the same
ballpark as the other short and thick winged aircraft, notably the Short
Wing Pipers.

With the low aspect ratio, thick wings, the optimum glide speed is
notably higher.  I did some extensive glide testing in my plane.  My
results were confounded by a faulty ASI but I can draw these conclusions
I think are valid:

1.  Glide ratio at a low airspeed is low.  The sink rate is quite high.

2.  The glide ratio at higher airspeeds is in the ballpark of other
aircraft, perhaps in the 10:1 range.

3.  The glide ratio to airspeed curve has a broad top with not much
glide ratio change with airspeed changes on either side of the optimum
speed.

4.  A Coupe that has a minimum airspeed (a stall in any other plane) of
50-55 mph will have its best glide ratio in the 75-85 mph range.
Gliding at 90 won't be much less than at the peak ratio.  Gliding at
lower speeds, like 65 or 60 is something else.

5.  I recommend you do some careful glide testing of your Coupe and find
out what its best glide airspeed IS.

6.  Even at the minimum airspeed with the greatest sink, the plane is
very controllable with full aileron authority and no chance of falling
off into a spin.

7.  If you were to glide down final at minimum airspeed, yoke against
the rear stop, you'd have no energy for a flare.  In that case, you'd
better drop the nose at a couple of hundred feet to gain airspeed/energy
for the flare or you will very likely fold under the nose gear and maybe
something worse.  This is psychologically hard to do as you are already
coming down fairly fast - dropping the nose is counter intuitive - but
it is still a very good idea (as long as you have __enough__ altitude
left).

Summary:  If you fly a zero power final approach at 75-85 mph, you are
in the good glide ratio range and the approach is not excessively steep
and is fully controllable.  This was my normal approach for many years.

We've got some much more extended discussions on the Ercoupe Owners
Club's website.  Here's a link to the FAQ:
