In what year did Gottlieb Daimler develop the power plant for aircraft?

Gottlieb Daimler developed the power plant for aircraft in 1885. This was a significant achievement in the evolution of aviation technology. In this year, Daimler, alongside his partner Wilhelm Maybach, created a lightweight engine that was crucial for powering early aircraft. Their development was foundational to the evolution of internal combustion engines and laid the groundwork for the design of aircraft engines that would follow.

The choice of 1885 is particularly notable because it was during that period that advancements in engine design were starting to show potential for aerial applications, which sparked interest in using engines for flight. Other years listed are either too early or too late, which does not align with Daimler's achievements and contributions to the field of engineering related to flight.
