ONE-VERSUS-ONE MANEUVERING, DISSIMILAR AIRCRAFT 141<br />

wise stated, to have an equal or better sustained turn rate <strong>and</strong> a tighter<br />

sustained turn radius than its high-wing-loaded opponent.<br />

Energy performance reflects a fighter's Ps under specified flight conditions.<br />

PS at a given airspeed is a function of the ratio of excess thrust to<br />

aircraft weight, as shown by Equation 4 in the Appendix, <strong>and</strong> is a measure<br />

of the aircraft's ability to climb or accelerate under those conditions. A<br />

fighter's T/W is a fairly good indicator of its energy performance. This ratio<br />

is usually stated in terms of static sea-level thrust <strong>and</strong> a representative<br />

combat weight. For piston-engine aircraft a parameter known as "power<br />

loading," the ratio of aircraft weight to brake horsepower (normally maximum<br />

sea-level power), is used rather than T/W. Both these measures may<br />

be misleading, however, since operating conditions of altitude <strong>and</strong> airspeed<br />

can affect two fighters in different ways. For example, a fighter with a<br />

relatively powerful normally aspirated piston engine may have lower<br />

power loading <strong>and</strong> better performance than a turbocharged fighter at low<br />

altitudes; but the turbocharged fighter would retain its power better at<br />

altitude <strong>and</strong> could have superior energy performance at higher levels.<br />

Likewise with jet engines, performance can vary greatly with inlet design,<br />

therefore a fighter may have higher T/W <strong>and</strong> better performance at slow<br />

speeds but be inferior at faster speeds.<br />

A fighter's aerodynamic efficiency, in particular its lift-to-drag ratio, is<br />

also vitally important to energy performance, especially at high G or high<br />

speed. In order to simplify this discussion, however, the term high T/W<br />

infers greater climb rate, faster acceleration, <strong>and</strong> higher maximum speed<br />

capability relative to the opponent.<br />

Obviously fighter performance can be a complex subject, <strong>and</strong> the numbers<br />

alone don't always tell the whole story. Development of effective<br />

tactics against dissimilar aircraft is, however, highly dependent on intimate<br />

knowledge of all aspects of relative fighter performance <strong>and</strong> design,<br />

as well as total familiarity by the pilot with his own aircraft <strong>and</strong> weapons<br />

system. Comparison testing, in which enemy aircraft are flown against<br />

friendly fighters, is undeniably the best method of gathering this crucial<br />

information.<br />

One of our achievements at this period was the "Rosarius Traveling Circus."<br />

This was a flight comprised of all air-worthy captured planes we could find.<br />

They traveled through the West from unit to unit in order to familiarize our<br />

pilots with enemy technique. The leaders could fly these enemy types themselves.<br />

In this way we found out that we had usually overrated their performance.<br />

The circus proved a great success.<br />

Low Wing Loading versus High Thrust-to-Weight<br />

Encounters between a low-wing-loaded fighter <strong>and</strong> an enemy fighter with<br />

greater T/W are quite common. In this case each fighter has performance<br />

advantages <strong>and</strong> disadvantages relative to its opponent. The engagement<br />

strategy is for the pilot to exploit the opponent's most serious weaknesses<br />

while taking full advantage of his own fighter's greatest strengths.<br />

The low-wing-loaded fighter's greatest performance advantages are
