What happens to air density as altitude increases?
✔✔Air density decreases as altitude increases.
How does temperature affect the speed of sound in the air?
✔✔Higher temperatures increase the speed of sound.
What is the primary force that opposes gravity in flight?
✔✔Lift.
How does increasing airspeed affect lift?
✔✔Increasing airspeed increases lift.
What happens to the center of gravity when fuel is burned from tanks located near the tail of an
aircraft?
✔✔The center of gravity moves forward.

,What is the relationship between pressure and volume in a confined gas when temperature
remains constant?
✔✔As pressure increases, volume decreases (Boyle’s Law).
Why does an aircraft require more runway distance to take off at high altitudes?
✔✔Air density is lower, reducing lift and engine performance.
How does humidity affect aircraft performance?
✔✔Higher humidity decreases air density, reducing performance.
What happens to an aircraft’s stall speed as weight increases?
✔✔Stall speed increases with weight.
Why do wings have a curved upper surface?
✔✔To create lower pressure above the wing, generating lift.
What effect does frost on a wing have on lift?
✔✔It disrupts smooth airflow and reduces lift.
2
, What is the term for the force that resists an aircraft’s motion through the air?
✔✔Drag.
What happens to engine performance when operating in high-density altitude conditions?
✔✔Engine performance decreases due to less oxygen available for combustion.
What happens to fuel volume when temperature increases?
✔✔Fuel expands as temperature increases.
Why does airspeed decrease in a climb if power is not adjusted?
✔✔More energy is used to overcome gravity, reducing forward speed.
How does an increase in load factor affect stall speed?
✔✔Stall speed increases as load factor increases.
What happens to pressure inside an aircraft cabin as it climbs if it is not pressurized?
✔✔Pressure decreases with altitude.
