Pilot Meant a Ship's Steersman Long Before Flight
A pilot flies an aircraft or guides a ship. The sea sense is the older one, and it explains pilot schemes and pilot lights.
A pilot flies an aircraft, or guides a ship through difficult water. The sea sense came first by three hundred years: a harbour pilot was a local expert who boarded a vessel to steer it safely into port, and the word probably traces back to Greek *pedon*, a steering oar. Aviation borrowed the title when aircraft appeared. That guiding sense explains the other uses: a *pilot scheme* leads the way for a bigger project, and a *pilot light* is the small flame that lights the larger burner.

Because a pilot goes first to make the way safe for what follows, exactly as a harbour pilot guides a ship in.
Which came first, sea or air?
The sea. Harbour pilots were named centuries before aircraft existed.
