The Rate of Climb of Turbo‐Jet Aircraft: A Method of Analysing Test Data to Establish the Climb Performance of an Aircraft Available to Purchase

CORRECTION of night test climb data to account for departure of the variables from standard or specified conditions presents a major problem owing to the large number of parameters involved. Atmospheric conditions invariably depart from standard I.C.A.N., and seldom do values of aircraft weight, speed and r.p.m. agree with those specified in a theoretical consideration of the problem. This article describes a method used to analyse climb data whereby climb performance of an aircraft may be established for specified conditions, speed for best rate of climb determined and comparison made with theoretical estimates. Rigid flying procedure is not required, and flying time is reduced to a minimum.
