Good Morning Mickey,

 

Thanks for that reference, but don't you think it slides rather rapidly  over 

some very important points?

 

It also does not address the problems of using either instrument as the  

prime source of information for recovery following a bout with vertigo.

 

If we are using a turn needle, (T&B) it has nothing about it that even  

suggests a

wing or whether or not the aircraft is level.  All it does is  tell us if the

airplane is yawing.  If it isn't yawing, it isn't  turning.  I think that

indication is MUCH easier for a confused pilot to  accept.



Go out someday in an aircraft equipped with a Turn Coordinator  and do a nice

strong Knife Edge.  Doesn't it seem rather strange to be  flying that knife

edge and also be looking at the turn coordinator that is  showing a "Wings

Level" indication?

 

Very Confusing to my old mind!



Do the same maneuver in an airplane  equipped with a T&B.  The T&B will be

sitting in the center for  the same reason the TC was showing wings level.



No turns and no yaw in a properly flown knife edge.  

 

Isn't it a lot easier for even we experienced aviators to accept that 

the T&B is doing what it should be doing than it is to accept that the 

wings level indication of the TC is proper?



The TC is always  compromised.  There is no way to determine if it is showing

a roll or a  yaw without using supporting information.



If a T&B needle is showing  an indication, the aircraft is yawing.  

 

No yaw, no turn.  

 

No turn, no graveyard spiral.

 

If the aircraft does not turn, it will survive!

 

Until such time as 'Lectric Bob provides us with a full time, low cost,  

autopilot to keep us from making excessive turning maneuvers, I vote for the  T&B.

Bob, I agree with you.  One nice thing about Wikipedia is that

the articles can be fixed right way, by you and me.

I've already made a small change to the wikipedia article on

the T&B: http://en.wikipedia.org/wiki/Turn_and_bank_indicator

They had a picture of a TC, so I just added a picture of a

T&B.  I'd like to update the text.  Feel free to send me any

updates or changes you would like to see in either of these

two articles, and I'll be happy to paste them in.  You can

do it yourself as well if you like, of course.  Takes about

2 minutes to create an account and start editing.

I've read several of your notes on the differences between

the TC and the T&B, and they have helped me a lot.  I think

it would be great to get this information out to a wider

audience, and I believe Wikipedia is a good start.

Thanks,

Mickey

Good Morning Mickey,

 

Thanks for the very kind words. I had no idea about how Wikipedia  works!

 

Very Interesting.  Definitely worthy of further thought.

 

Happy  Skies,
