Mooney TLS Bravo

So what is a non smooth landing?
How hard is too hard?

Perhaps 1.5 G plus if you have an accelerometer? In the Navy test trials the T-34 was dead dropped from over ten feet, it blew the tyres but otherwise no airframe or landing gear damage.

Outta Navy but in the civilian and civilized Airbus world:
A hard landing is defined as a landing with a vertical acceleration of more than 2.6 g at the center of gravity or a v/s of more than 600 ft/min.

An overweight landing is defined as a landing at more than the maximum landing weight with a vertical acceleration of more then 1.7 g at center of gravity or a v/s of more then 360 ft/min.

On the A-320 one can print a load report #15, just outta interest. An auto-print of the same would mean trouble, such as tea but no biscuits with the base or chief pilot 🙈

I went through the POH but I couldn’t find a definition unfortunately. I also don’t know what is meant by a smooth landing. I suspect it’s up to the pilot to judge and be honest with himself how soft was the touchdown.

Other than a few Mooney M-18 Mites and M-10 Cadets, aren’t they all M20s? Those in combination are less than 350 planes.

Are those POH figures achievable in real life?

Haven’t been able to test them yet but anyway some of those power settings are inadvisable due to too much wear on the engine, TC and exhaust. Also fuel efficiency at some of higher power settings that are advisable is much worse than what that image says simply because you can’t run those settings at peak TIT. You have to go way richer to keep the temps reasonable.

Perhaps 27"/2200RPM numbers might be doable (65% power). I’ll see when I start flying in a couple of weeks.

27"/2200RPM

AFAIK max allowable Lyco oversquare on normally aspirated is 4", as in 26/2200 or 27/2300…

There are operating diagrams such as this but no concept of “over square”.
