Front

What are the standard temperature and pressure values for sea level?

Back

15 degrees C and 29.92" Hg.

Front

Knowing the pressure altitude is important to aircraft performance because it can be used as a tool to arrive at _____________.

Back

density altitude

Front

Pressure altitude corrects for the difference between _______ and standard pressure.

Back

barometric pressure

Front

Which factor would tend to increase the density altitude at a given airport?

Back

increase in ambient temperature

Front

Pressure altitude is calculated from (29.92 – 28.92) × 1,000 + 3,500. What information do these numbers give? Options: The barometric pressure is 29.92 ”Hg and the elevation is 1,000 feet; The barometric pressure is 28.92 ”Hg and the elevation is 3,500 feet; The barometric pressure is 29.92 ”Hg and the elevation is 3,500 feet; The barometric pressure is 28.92 ”Hg and the elevation is 1,000 feet.

Back

The barometric pressure is 28.92 ”Hg and the elevation is 3,500 feet.

Front

Which statement is true about an object moving through a fluid?

Back

Fluid friction increases as the object's velocity increases.

Front

Which formula is used for calculating density altitude?
Options: mass + volume, PA+ [120 (OAT - ISA)], (29.92 - Barometric Pressure) 1,000 + Elevation, 15 (21,000 x PA)

Back

PA+ [120 (OAT - ISA)]

Front

Atmospheric pressure is _______ to air density.

Back

directly proportional

Front

The “standard day” serves as a universal baseline for measuring _______. Options: atmospheric pressure, barometric temperature, density altitude, ground roll.

Back

atmospheric pressure

Front

The Magnus Effect occurs because a spinning object drags the air around it. The air being dragged by the object interacts with the surrounding air to create regions of __________.

Back

high and low pressure
