Another AirBus-320 question

Well, let's do the math. The 320 has a best glide speed (max distance) of
about 220 mph while dropping about 1000 fpm at this speed. 220 mph = 3.66
mpm, or about 19,360 fpm. If you go forward 19,360 feet while dropping 1000
feet this is about a 19.36:1 glide ratio. Allowing for other factors not
presented in the data I've seen, 15:1 is eminently reasonable for the A-320.

I have seen reported that the AirBus-320 has a glide ratio of 1:15.
That was what our pilots told us the wings on Cessna 180-182 (L-19)'s
glide ratio was.
It does not seem consistent that a swept, thin airfoil, wing would have
the same glide ratio as the Cessna.
It is correct the AB-320 has a 1:15 glide ratio at zero power?
Those pilots also said a B-52 and a grand piano have identical glide
ratios.
