Summary

Performance measurements for turbo-jet and turbo-prop aircraft are most conveniently reduced to standard conditions by the use of graphical methods. The case of rate of climb presents difficulties if readings are taken in the normal way during continuous climbs, because of the variation of weight, temperature, pressure and optimum climbing speed with height.

Since rate of climb is proportional to the product of speed and acceleration in level flight, these quantities could be measured and used to determine the rate of climb at any height.

The advantages of the method are listed and the technique required of the pilot examined. An automatic observer, including a longitudinal accelerometer, reading, in some cases, to within 0.001g, is necessary.
