INCIDENCE settings

[randy10926 at comcast.net]

More than looks down.  The nose is down in a B-52; even in a climb.  The B-52 wing has a high angle of attack, it is a design feature to help the wing generate enough lift at gross weight.  When the B-52 was designed the knowledge base on how to design a wing of that huge size for the planned gross weight and speed was small.  My guess is Boeing had to use models and wind tunnels to get data to use for the design.  I used to live in the Seattle area in 79 and the model shop was very busy back then.

I remember wheel landing in cubs, champs, chiefs, stinstons, L-4s, L-5s, L-19s, Wacos and etc.  God I must be getting really old.  Ah a flight in a T-34 would be fun; again.

Lets not forget the B52 looks like it is nose down on takeoff.

Remember the Hobie Hawk glider? It flew nose down -- WAY down. It was designed that way. It was not a balance issue at all.


I do remember the Hobie Hawk and how it flew. 

A J-3 Cub on a proper final approach looks nose-down as well, but many pilots won't let it come in that way. As a result, they'll never enjoy a wheel landing on a Cub.

This discussion also tapped into one of my pet peeves: Guy sees an 
airplane flying around with the tail low and announces, "That airplane
is tail heavy". Probably wrong. The incidence relationship between
the wing and the horizontal tail is probably incorrect. The CG has an 
effect, but the condition is usually caused by a bad trim setup. Now I 
feel better.
