		  Good Evening Bob,



I do agree that having a wing leveler is a great idea.



I even like the way Mooney hooked it up so that we had to press on a 

button any time we wanted to hand fly the airplane, but I do not believe 

you will find ANY wing leveler that can be installed as cheaply as can a 

venturi powered vacuum T&B.



An electrically powered T&B is even cheaper if you do not count the cost 

of having an electrical system to power it.


	


   But, like all presentations under glass, it depends on the

   integrity of a sensor/display/perception/reaction servo

   loop of which includes a human having to work with the

   reality of a rare but now present failure. N/B/AS is a

   useful but exceedingly lousy alternative to stable gyros.



   I wouldn't own an airplane without a gps aided wing

   leveler just because it makes flying so much more

   relaxed . . . whether the stuff under the glass is

   working or not and a whole lot lower risk when it

   is not.

Good Evening Bob,   

 May I take that to mean that you would want a GPS aided wing leveler in a  Stearman?, Piper Cub?, Luscombe?, Cessna 140? Cessna 172, Beech Musketeer?,  Beech Bonanza? North American AT-6? Twin Beech?

  

 Where would you draw the line? All of the above? None of the above? Some of  the above?

  

 I have never flown any airplane that had a GPS aided wing lever though I  have flown and owned plenty that did have wing levelers.

  

 We all have to make individual decisions on what we feel meets our  individual level of risk, but requiring a GPS aided wing leveler is not real  high on my list of necessities. Interesting that you think such a device is  imperative.

  

 Just goes to show, there is a wide range of desires among us  all. 

  

 Happy  Skies,

That's the difference between a pilot and a cockpit resource manager
