Key Takeaways Air density affects aircraft performance, including lift, engine power, and propeller effectiveness. Factors influencing air density include altitude, temperature, pressure, and humidity. High-density altitude reduces aircraft performance, requiring flight adjustments. What Is Air Density?

If you add only the given weights (usually weights are defined for pilot, passengers, fuel, and cargo), the total will be far too low and your answer won’t make sense. The important thing to remember with these questions is that density altitude changes inversely with altitude.

higher density altitude), because water molecules (molecular weight = 18) displace either nitrogen or oxygen molecules. static heaviness”), any large cargo that was off-loaded had to be immediately replaced with something of equal weight or the lift gas had to be vented.
