43. Why do pilots calculate density altitude? Pilots calculate density altitude to assess aircraft performance and safety during takeoff, landing, and flight. High density altitude, caused by high altitude and temperature, can reduce aircraft lift and engine performance.
44. Is dry air more dense? Dry air and moist air at the same temperature and pressure have similar densities. However, dry air is slightly denser than moist air because water vapor has a lower molecular weight than dry air.
45. Why is air denser in winter? Air is denser in winter because lower temperatures cause the air molecules to come closer together, resulting in higher air density.
