Glide Chart

[YankeeClipper]

By any chance does the POH cite a glide chart for both engines out?

13.2 ratio? Really?

Thanks, btw.

[YankeeClipper]

Not to belabor the point, but is 13.2 really even roughly correct? This would well exceed the same data for an M20F, and approach mid-to-late century gliders. Given the recent tail of a near double engine failure, this would be good information to have. I understand of course that weight and exterior contour changes can play a large role in the final outcome.

part of the reason twins have a relatively good glide ratio is that the charts assume both props are feathered, which reduces drag considerably.

[YankeeClipper]

But the M20s also feather, and they only advertise something around 11ish. Add to this, fwiw, that the Mooneys earn their living by being just a little more slippery than other aircraft in their class.

Could it be that the small twin booms are that much less drag than a full empennage?

[WebMaster]

Mooney's are advertised as a little more slippery, but they also have much higher wing loadings, hence lower glide ratios

FWIW
Here is the Pressurized H model glide distance

Hi All,

Here is the chart from my 1977 337 G.
