I.    Introduction

              Flight tests were conducted on the P-63A-9 airplane, AAF No. 42-69417, at Wright Field, Dayton, Ohio from 21 September 1944 to 31 March 1945. These tests were conducted at the request of the Project Engineer, Capt. E.E. Sands, Fighter Branch, Production Section, Procurement Division in order to obtain war emergency performance in level flight and climb. All tests were flown by Major R.B. Johnston with Capt. N.A. Krause and Lt. J.L. Corkill as Flight Test Engineers.

II.   Summary

              In general, handling characteristics, controllability, and stability of this airplane are satisfactory and comparable to other P-63 model airplanes. No comments or comparison can be made of performance obtained as no guarantees or estimated results have been submitted by the manufacturer at this power.

            The principal results of performance obtained are as follows:

A.High speed (58" and 3000 RPM) 16,000 Ft.400.5 MPH
B.Maximum speed at sea level (75" and 3000 RPM)366    MPH
C.Rate of Climb
1.   Sea Level (75" and 3000 RPM)3600 Ft./Min.
2.   Time to climb to service ceiling31.2 Min.

              All performance data is corrected to standard atmosphere and level flight data is corrected to weight at altitude.
