AIR DENSITY

Density is... at poles than equator

• Higher
• Lower
• Same

Above 8km density is....at poles than at equator

• Higher
• Lower
• Same

The altitude in ISA at which air density is the same as the observed density is

• Density Altitude
• ISA Density
• Real Density

Density is usually expressed as....

• Kg/sq m
• g/cu m
• N/sq m

Higher density altitude means....density

• Higher
• Lower
• Same

For given pressure and temperature moist air has density

• Higher
• Lower
• Same

Air is less denser in

• High Altitude
• Warm Air
• High humidity
• All these

Density altide may be defined as

• The altitude in ISA at which the prevailing pressure occurs
• The altitude in ISA at which the prevailing density occurs
• The altitude in actual atmosphere at which the prevailing density occurs

Temperature being constant, if pressure increase the density altitude

• increase
• lowers
• remains the same

For every 1*C change in temperature, density altitude differs from pressure altitude by

• 33 ft
• 100 ft
• 120 ft
• 210 ft
