REALISM RATING F-51D-30NA by UP1.8

1 PURPOSE
The purpose of this analysis is to measure how close the performance of the simulated plane matches the performance of the real plane. This measurement is accomplished in several ways. In section 3 the PERFORMANCE COMPARISON provides a direct comparison between the simulated plane data and the real plane data. The error and percent error between the simulated plane data and real plane data is calculated per test type. From either of these two graphs the reader can see how well the simulated plane data matches the real plane data per altitude. Section 4 the REALISM RATING is provided for those readers who may have trouble reading performance data, error and/or percent error graphs. The REALISM RATING section simplifies the results into an easy to read bar graph that that can be used as an overall rating of how well the simulated plane data matches the real plane data.

3 PERFORMANCE COMPARISON
In WWII there were primarily two types of tests done to measure the performance of a plane; One the rate of climb (ROC) and two the top speed per altitude (TSPA). The problem is finding real world data to compare to that applies directly to the simulated plane. In the absence of such data substitutes can be used, if they are close to the simulated plane. This substituted data is typically test data from a variant of the simulated plane. In such cases the real world data may be adjusted to account for differences between the real plane and the simulated plane. Differences like engine horse power, power settings, external stores, gross weight, etc. The process for adjusting the real world data is open to debate and is why any assumptions used and the reasoning behind the adjustments are provided in section 5 for review.
