Does Anyone Land their F or J with No Flaps?

My perception is that I get a better angle of climb for obstacle clearance. Also, I prefer to have more margin against stalling. 

I’d say that both of those are probably more perception than reality.

Angle of climb (AOC) could be a bit more complicated.  AOC = (T-D)/W   Drag is proportional to velocity squared, so reducing climb speed could help AOC.  Looks like I'll be doing some flight testing once my flaps are fixed.

You can reduce speed with pitch. I do not believe climb angle is improved with parasitic drag.

One of the smoothest, and beautiful landings you'll ever have in a short, mid or long body is a no flap landing over the threshold at 90kts.

 

Now takeoffs in a Mid or long body are best with the appropriate TO flaps. Shorts handle fine with some or none. Loaded or not.

When you change wing geometry…

There is a follow-on affect to all the performance numbers…

From most important to not very important…

Stall speed is really important… disaster occurs immediately

Vx is kind of important… you might get seconds before disaster to do something differently…

Vy is not so important… you might be off, causing numbers to the right of the decimal point to shift in your efficiency… or a few minutes before the window fills with mountainous terrain…

 

When you look into newer Mooney’s POHs… you might see Vx and Vy and best glide are very weight dependent… about 10kias?

Looking these up isn’t always easy to find either…

PP thoughts only, based on old fuzzy memory… so, always look these up before use.
