Abstract

The uses to which a lift‐coefficient indicator could be put are presented, and it is suggested that a good case could be made for displacing the airspeed‐indicator on the pilot's panel at least. The chief advantages accompanying the use of the lift‐coefficient indicator lie in its contributions to safety and in rationalizing flight conditions at the various flying weights of each aircraft. A type of indicator is considered in detail which utilizes the relationship between aerofoil surface‐pressures and various parameters notably angle of attack and Mach No. It is shown that although complex relationships may exist, it is possible to evolve a simple solution. Reliability in all atmosphere conditions is attained by design‐detail, and accuracy is expected to approach 1 per cent.
