1. What is a practical definition density altitude – one that would clearly explain the concept to a general aviation pilot-in-training?
2. What are the main factors that affect density altitude, and what changes in each of those factors cause the density altitude to increase? What are the hazardous effects of a high-density altitude on aircraft performance?
3. Is density altitude only an issue at high elevation airports? Explain. What season of the year is density altitude generally highest, and what time(s) of day during this season are high-density altitude conditions most critical? Explain.
4. What should be the precautions that are taken, and preparations made, when planning a flight in high-density altitude conditions?
