. The individual actions of aces were widely reported and the image was disseminated of the ace as a chivalrous knight reminiscent of a bygone era. For a brief early period when air-to-air combat was just being invented, the exceptionally skilled pilot could shape the battle in the skies. For most of the war, however, the image of the ace had little to do with the reality of air warfare, in which fighters fought in formation and
air superiority depended heavily on the relative availability of resources. The use of the term ace to describe these pilots began in World War I, when French newspapers described
Adolphe Pégoud, as (the ace) after he became the first pilot to down five German aircraft. The British initially used the term "star-turns" (a show business term).

History
World War I

World War I introduced the systematic use of true single-seat fighter aircraft, with enough speed and agility to catch and maintain contact with targets in the air, coupled with armament sufficiently powerful to destroy the targets. Aerial combat became a prominent feature with the
Fokker Scourge
The Fokker Scourge (Fokker Scare) occurred during the First World War from Kurt Wintgens#First victory using a synchronized gun, July 1915 to early 1916.Franks 2001, p. 1. Imperial German Flying Corps () units, equipped with (Fokker monoplane) ...
, in the last half of 1915. This was also the beginning of a long-standing trend in warfare, showing statistically that approximately five percent of combat pilots account for the majority of air-to-air victories.
As the
German fighter squadrons usually fought well within German lines, it was practicable to establish and maintain very strict guidelines for the official recognition of victory claims by German pilots. Shared victories were either credited to one of the pilots concerned or to the unit as a whole – the destruction of the aircraft had to be physically confirmed by locating its wreckage, or an independent witness to the destruction had to be found. Victories were also counted for aircraft forced down within German lines, as this usually resulted in the death or capture of the enemy aircrew.
Allied fighter pilots fought mostly in German-held airspace and were often not in a position to confirm that an enemy aircraft had crashed, so these victories were frequently claimed as "driven down", "forced to land", or "out of control" (called "probables" in later wars). These victories were usually included in a pilot's totals and citations for decorations.
The British high command considered the praise of fighter pilots to be detrimental to equally brave bombers and reconnaissance aircrew – so that the British air services did not publish official statistics on the successes of individuals. Nonetheless, some pilots did become famous through press coverage,
making the British system for the recognition of successful fighter pilots much more informal and somewhat inconsistent. One pilot,
Arthur Gould Lee, described his own score in a letter to his wife as "Eleven, five by me solo — the rest shared", adding that he was "miles from being an ace". This shows that his
No. 46 Squadron RAF counted shared kills, but separately from "solo" ones—one of a number of factors that seems to have varied from unit to unit. Also evident is that Lee considered a higher figure than five kills to be necessary for "ace" status. Aviation historians credit him as an ace with two enemy aircraft destroyed and five driven down out of control, for a total of seven victories.
Other Allied countries, such as France and Italy, fell somewhere in between the very strict German approach and the relatively casual British one. They usually demanded independent witnessing of the destruction of an aircraft, making confirmation of victories scored in enemy territory very difficult.
[Franks and Bailey 1992, p. 6.] The Belgian crediting system sometimes included "out of control" to be counted as a victory.

adopted French standards for evaluating victories, with two exceptions – during the summer 1918, while flying under the operational control of the British, the
17th Aero Squadron and the 148th Aero Squadron used British standards.
American newsmen, in their correspondence to their papers, decided that five victories were the minimum needed to become an ace.
While "ace" status was generally won only by fighter pilots, bombers and reconnaissance crews on both sides also destroyed some enemy aircraft, typically in defending themselves from attack. The most notable example of a non-pilot ace in World War I is
Charles George Gass with 39 accredited aerial victories.
Between the world wars

A number of factors probably contributed to the very high totals of the top German aces. For a limited period (especially during

s (sometimes well over 1000) than their Allied counterparts. Moreover, they often kept flying combat missions until they were captured, incapacitated, or killed, while successful Allied pilots were usually either promoted to positions involving less combat flying or routinely rotated back to training bases to pass their valuable combat knowledge to younger pilots. An imbalance in the number of targets available also contributed to the apparently lower numbers on the Allied side, since the
number of operational Luftwaffe fighters was normally well below 1,500, with the total aircraft number never exceeding 5,000, and
the total aircraft production of the Allies being nearly triple that of the other side. A difference in tactics might have been a factor as well;
Erich Hartmann, for example, stated "See if there is a straggler or an uncertain pilot among the enemy... Shoot him down", which would have been an efficient and relatively low-risk way of increasing the number of kills. At the same time, the Soviet 1943 "Instruction For Air Combat" stated that the first priority must be the enemy commander, which was a much riskier task, but one giving the highest return in case of a success.

purposes, so most air forces expend considerable effort to ensure accuracy in victory claims. In World War II, the aircraft
gun camera came into general usage by the Luftwaffe as well as the RAF and USAAF, partly in hope of alleviating inaccurate victory claims.
World War I aerial victory accuracy
In World War I the
standards for confirmation of aerial victories were developed. The most strict were the German and French ones which required both the existence of traceable wrecks or observations of independent observers. In contrast to this, the British system also accepted single claims of the pilots and deeds such as enemy planes "out of control", "driven down" and "forced to land".
Aerial victories were also divided among different pilots. This led to vast overclaims on the British and partially on the US American side. Some air forces, such as the USAAF, also included kills on the ground as victories.
The most accurate figures usually belong to the air arm fighting over its own territory, where many wrecks can be located, and even identified, and where shot down enemy aircrews are either killed or captured. It is for this reason that at least 76 of the 80 aircraft credited to
Manfred von Richthofen can be tied to known British losses. The German
Jagdstaffeln flew defensively, on their own side of the lines, in part due to General
Hugh Trenchard's policy of offensive patrol.
