Why was surprise important in World War I fighter tactics?

In the context of World War I air warfare, the element of surprise was a fundamental tactical principle that proved more effective than complex aerial maneuvers. Because a pilot’s only warning system was the naked eye, "jumping" or "bouncing" unsuspecting victims accounted for more aerial kills than the spectacular aerobatics associated with dogfighting.1

To achieve this surprise, attacking fighters utilized specific techniques:
* Positioning: Pilots attempted to approach from the rear or dive out of the sun, where they could not be easily seen by the target.1
* Tactical Advantage: By catching an enemy unaware, the attacker could secure a decisive advantage before the victim had the opportunity to react or engage in defensive maneuvers.1

This emphasis on surprise was a direct result of the limitations of early aviation technology, where effective combat ranges were very short—often no more than 200 yards—and communication was restricted to basic hand signals or flares. Consequently, gaining the upper hand through stealth and positioning was essential for survival and success in the air.1
