The cockpit layout is excellent, but visibility is poor on the ground and only fair in level flight. The stability about all axes is good and the rate of roll is excellent, however, the radius of turn is fairly large for a fighter. The airplane is very maneuverable with good controllability at indicated speeds to 400 MPH. The rate of climb is good and the high speed in level flight is exceptionally good at all altitudes, from sea level to 40,000 feet. Its long range makes it ideal for escort purposes, and its performance as a fighter aircraft is better or at least equal to that of any enemy fighter that might be encountered. The P-51B is a single engine, low wing, long range fighter. ![]() Memorandum Report on Pursuit Single Engine P-51B-1-NA AAF No. Time to Climb 3,000 r.p.m., oil and coolant flaps wide open.
