Flight components are the parts of an aircraft that make up its structure and enable it to fly. STAIRS (6 letters) is a set of steps leading from one level of a building to another, usually inside the building. Steps (5 letters) are individual pieces of a staircase, usually made of wood or stone. Risers (6 letters) are the vertical boards that form the back of each step in a staircase. Together, these components form the structure of a flight, allowing it to take off and land safely.
