Volume 1. Aircraft Performance. Chapter 12. Data Reduction and Corrections to Standard Day.
Abstract
An ancient report, from the early days of flying, discussing the crash of a 'Jenny' shortly after takeoff on a hot summer day, concluded that the primary cause was 'there was no lift in the air that day.' The determination of the effects of nonstandard atmospheric conditions on aircraft performance has come a long way since then. These determinations are particularly important in flight test, since performance specifications must be written for some set of 'standard' conditions, and flight tests are not usually conducted on 'standard' days. Modern computer data reduction capabilities have greatly reduced the manual labor required for performance calculations. On the other hand, they tend to hide assumptions and factors which can turn out to be extremely important in performance testing. This section examines how test day performance data may be reduced or related to performance under standard conditions. Emphasis is placed on the relationship between data reduction and available instrumentation. The techniques are those used in the TPS performance data reduction programs, which are similar to those used in AFFTC flight test programs.
