Situation Completely Fluid - Caravelle Jet Transport Hydraulic System, Operation and Maintenance

This paper is a brief review of one airline's experience with a jet transport that uses only hydraulics for flight controls and services. The Sud Caravelle is not a new airplane. But it does embody design concepts that are the forerunners of what we must anticipate in future transport aircraft. Discussion will include:

• Brief review of hydraulic system circuits and the redundancy for complete flight safety back up
• The need for operator concern over system integrity and internal leakage
• The periodic checks and measurements used to monitor and control the system integrity

These contemporary problems and procedures give us some insight into the more sophisticated matters of the future that must concern the operation of a Supersonic Transport.
