Caravelle Yokes

Sun Jan 17, 2010 10:13 pm

What were those odd looking side-yokes on Caravelles?
A precursor of the side-stick?
Does anyone have good photos?

Quoting Kimon (Thread starter):

Those are the main yokes...same function as in any other yoke-based airplane, just different mounting.

Not really...the motion on the yoke is the same as a conventional between-the-legs yoke.

This is the best one I could find:

Illustrates quite clearly how much DH Comet there was in the pointy end of the Caravelle

The deHavilland Comet and SUD Caravelle designs, although looking very similar at the pointy end, were entirely different, from a systems perspective.
The Caravelle design was very advanced for its time, fully hydraulic powered flight controls, and many redundant systems.
Also, the Caravelle was the first jet transport airplane to perform CATIIIB autolands, using a Lear designed duplex autopilot system.
This design was used (as I recall) by the French Post Office for air mail, however, not for passenger ops.
Passenger ops required a triplex autoflight system, such as the one designed by Smiths and installed on the HS.121 Trident.

Well, the allready old by that time DC-2 had it, so hardly a "first" or some kind of "sidestick precursor" - remember by the time of DC-2 the computers were merely imagination (well, sorta).

Sidesticks do not really require computers, although I guess you need fully powered controls to make them really practical.

The Caravelle was also the first clean-swept wing (commercial aviation) and rear-fuselage mounted engines.

The Caravelle and Comet noses weren't just very similar, Sud Aviation re-used the DH design for the early Caravelle marks. What went inside the structure was clearly entirely different.

The Comet also had fully hydraulic powered flying controls
